Date Description Recorder
18 Jun Harpenden Common on a rather hot and sunny afternoon: 20+ Meadow Brown (all males as far as I could see); 20+ Small Heath with many clashing males, usually in twos but also in threes and fours; 10+ Marbled White (all males); 6 Ringlet; 10+ Common Blue ; 1 Speckled Wood; 1 Six-spot Burnet; and many Crambus pascuella. Small Heath seem to be having an exceptionally good year and I have never seen so many on the Common. Of note, one of the Small Heath lacked the eye-spot on the underside of the forewing, possibly referable to ab. caeca David Hunt

I disturbed a lot of Meadow Browns and Speckled Woods when walking along the main ride but I did not count them. Sadly no White Admirals or Silver-washed Fritillaries as too cloudy Miles Attenborough

15 Jun We were delighted to find a White Admiral on Bricket Wood Common this afternoon. We initially disturbed it feeding on bramble in the clearing. It flew off into the wood and the sun went in but we waited for the next sunny interval and it duly returned, again feeding on bramble.

11 Jun I went to Symonshyde Great Wood to check on whether any Silver-washed Fritillary had emerged. Alas not. But plenty of Speckled Wood (20+), 2 Meadow Brown, 1 Large Skipper and a couple of interesting small butterflies fluttering about the upper branches of an elm and periodically landing on the leaves. I eventually managed to get my optics on them and, to my surprise, found that they were both Small Heath.

I have seen Small Heaths here before but they are hardly abundant, and not necessarily egg-laying/breeding in the vicinity. Having said that, this year the grazing (courtesy of a mixture of cows and horses) has been lighter than usual which has probably helped them to survive/spread. Also Yellow Shell moth Jeremy Soane

3 Jun Hounslow: Sunshine throughout a morning walk, the highlights were two 2 "old" species rather than new ones. I spent a ridiculous amount of time following what I was sure was a Green-veined White and was duly rewarded, when it settled, as perhaps I should be in these circumstances, by the sight of a rather faded female Orange-tip dragging her species into June. My pleasure at this fairly mundane experience was all the more exaggerated because moments earlier I'd been watching a Green Hairstreak. This individual I at first saw as a female Common Blue, then some unknown species and only finally as what it was. Virtually all the colouring had gone from its wings with only a thin band of green visible nearest its body. The remains of the "hairstreaks" were just about apparent if you looked close enough but it was the characteristic closed wings and movement from Broom-tips to Broom-tips that left no doubt.
Here are the full details: Hounslow Heath: Speckled Wood: 3 Orange-tip: 1 Green-veined White: 1 Small White: 1 Heath--ex-Golf Course: Speckled Wood: 1 Small Heath: 4 Common Blue: 1 River Crane: Common Blue: 3 Marshalling Yards: Speckled Wood: 4 Brown Argus: 1 Common Blue: 17 Green-veined White: 1 Small Heath: 4 Pevensey: Comma: 1 Speckled Wood: 2 Small Heath: 1 Heath/Heather/Railway: Small Heath: 3 Common Blue: 1 Green Hairstreak: 1 Speckled Wood: 1 plus 3 Cinnabar, 3 Burnet Companion, 2 Silver Y and 1 Mother Shipton moths across the site

30 May We visited Frogmore in the hope of finding some Grizzled Skippers roosting but despite searching all the areas accessible we found none. Recent rain meant that water levels had risen so getting around the site was even more difficult in places. We then decided to look for Grizzled Skipper eggs, and to our amazement we found 41 scattered across the site, some in areas we have previously never seen Grizzled Skipper. All bar 3 were on Agrimony with 3 eggs found on the top of the leaves, and 3 were found on Wild Strawberry. We don't doubt that eggs are laid on Strawberry and Cinquefoil as observed at other sites but Agrimony is by far the easiest to search. Of these 41 eggs, 7 had hatched - we found two minute caterpillars on two leaves where they were beginning to form tents and one where the caterpillar was already in a tent. At the beginning most other butterflies and moths were roosting but gradually by about 3.30 the day was brightening up and 3 adult Grizzled Skipper were seen near the entrance. Also Common Blue and Brown Argus became active and combined with the roost counts we recorded 14 Brown Argus, 14 Common Blue, 6 Small Heath, 1 Small Copper, 4 Silver Y, 1 Light Emerald moth, 11 Cinnabar and 2 Treble-bars roosting together and a Mullein moth caterpillar Liz Goodyear

23 May Today, we held an intensive survey of both north and south pits at Waterford Heath to try and understand how the Grizzled Skipper 'ticks' at these two sites.
We started at the north pit just after 8.30 in cloudy, windy and poor conditions. Starting at the cliff face under the Sacombe Road we quickly found several roosting Grizzled Skippers but numbers started to decrease as we walked towards the north end of the pit and around to the railway line. Some brightness allowed some Grizzled Skippers to probably come off their roosts. Checking the sex of the individuals found, the majority on the north pit were male! We also found 1 egg on Common Agrimony. Counts on the north pit were 24 Grizzled Skipper plus 1 dead on a seed head, 28 Brown Argus, 5 Common Blue, 11 Cinnabar and 2 Silver Y moths.
We then went to the South Pit where most butterflies were now flying in the afternoon sun. A thorough search of key areas found 27 Grizzled Skipper including 1 female roosting at the end of the survey near the entrance! We also followed several female Grizzled Skippers including 1 that laid eggs on both Agrimony and Creeping Cinquefoil. 3 other eggs were found on Agrimony. Also seen were 49 Brown Argus, 37 Common Blue, 12 Small Heath, 4 Small Copper, 1 Small White, 1 Peacock, 5 Holly Blue (including at least one egg laying on Goat's Rue), 1 Comma, 1 Brimstone, 1 Orange-tip, 1 Large White, 1 Green-veined White, 9 Cinnabar, 4 Burnet Companion, 1 Silver Y and 1 Diamond-back moth.(Finishing at 4.25)

Also seen were several Large White, Green-veined White, Holly Blue and Speckled Wood plus a single Small Tortoiseshell.

16 May I met Andrew at 8.30 and we first walked Rickneys in cool, cloudy and windy conditions. Initially all this produced was one Grizzled Skipper roosting on Forget-me-not at the bottom of the 'key bank'. We then walked across the bottom of the pit and saw nothing but returning via the edge of Bardon Clumps we found two more Grizzled Skippers roosting on St John's Wort. Returning up the 'bank' it appeared we had missed a further SIX all also roosting on Forget-me-not at the bottom. We then drove to our meeting point with Network Rail for our annual escorted trackside visit north of Hertford - earlier I had been rung, "did I want to go ahead as it wasn't sunny?". "Yes I said!!!". Having signed all our safety forms, we set off (in hard hats, and high viz gear) just before 10 am and the conditions were still cool, cloudy and very windy and quickly we had found 13 roosting Grizzled Skippers all on St John's Wort seed heads but then the sun tried to come out, not much but enough to disturb the Grizzled Skippers from their slumber and the next one seen was in flight. Further down the track, one further Grizzled Skipper was found half basking and then roosting on Forget-me-not (this in an area we rarely find them) and on the other side of the track one more Grizzled Skipper was found roosting on St John's Wort. It was disappointing as the count was less than last year but the problem was that the sun had also tried to shine and we feel that a few Grizzled Skipper had come off roost. Also seen were 5 Cinnabar moths, 1 Brown Argus and a Small Heath as well as 2 Toadflax Brocade and 2 Pale Tussock moths roosting. We didn't walk the area north of this key area towards the cutting, as the habitat has deteriorated and for safety reasons we aren't allowed to walk too close to the trackside. We then went to Welwyn North Station and looked very thoroughly at the area between the two tunnels but no butterflies were recorded. We would like to thank Network Rail for their continued support in allowing us to survey these key areas. Finally we went to Frogmore and despite searching for two hours our final count was 4 roosting Grizzled Skipper all on Forget-me-not! Liz Goodyear

13 May After yesterday's dismal weather and an uninspiring forecast for today it was no surprise that the Hounslow Heath Field Trip was attended by just Paul Busby and myself. Many thanks Paul! We had a pleasant walk in slowly improving weather but butterflies were limited to the three smaller whites (with Green-veined White dominating) and Speckled Wood. The highlight was not a butterfly but something I think new to me - if I had to guess I'd say female Broad-bodied Chaser. It looked a bit like a Hornet but I didn't get a very good view and could well be far off in this guess. With Paul we completed the Hairstreak walk (3 actual species and a fantasy Brown) and he then departed whilst I went back to my normal walk. Much of this, including the Marshalling Yards and Pevensey was similar to the earlier walk but by the time I had returned through the tunnel it was much warmer and sunny. Whilst identifying a Small White I spotted my first Green Hairstreak of the day perched on a Bramble leaf next to the river. This inspired me to return home via the exact same stretch Paul and I had walked earlier and almost immediately two Green Hairstreaks fluttered amongst the Broom. I lost sight of one but the other perched on the tip of a shoot probably laying but I'm never very sure I can sort leaf buds from eggs and don't like to poke around for fear of damaging an egg. There was one further sighting in the vicinity of these two which I haven't added to the count but much further along the path a third Green Hairstreak was seen, again on Broom. Here are the full stats omitting the initial walk with Paul: Marshalling Yards: Speckled Wood: 1 Green-veined White: 4 Holly Blue: 1 Pevensey: Green-veined White: 1 Small White: 1 River Crane: Small White: 2 Green Hairstreak: 1 ex-Golf Course--Heath: Orange-Tip: 2 Green-veined White: 1 Heath/Heather/Railway: Small White: 1 Green Hairstreak: 3 and back home in my garden Holly Blue: 1 Peter Gore

11 May At Stanwell Moor, a similar sort of day as 10th, but the intermittent sunshine made the Orange Tips more amenable to photography.

We walked the west side of Waterford Heath north towards the railway slopes and on this side recorded 12 Grizzled Skipper, and a Silver Y moth. We then crossed the road and entered Waterford Heath south at 14:20. This was much slower and nothing was seen in the old filter beds but across the main pit and Sacombe Road slope we counted 10 Grizzled Skipper and our first Latticed Heath. Returning to the North Pit at 16:00 we saw 2 more Silver Y. Throughout the day we saw several Large White and wondered if there had been a migrant movement of Large White and Silver Y? The east side of the north pit was also slow until we found a mating pair and then under the conifers near the north entrance 4 more were seen in the brambles. The total for the North Pit was 17! We had also seen on both pits incidents of chases and clashes but no egg laying females. We then decided we would visit Frogmore arriving at 17:30 although the reading in the car was 20 C things were slowing down and as the pit is still very flooded - access to some key areas impossible. The count here was a poor 3! 2 individuals were found roosting one on hawthorn, the other on Forget-me-not. Also recorded was a Latticed Heath. In total 8 hours by 2 people searching = 16 hours! Total for day = 56! Liz Goodyear

5 May Hounslow: Sunshine throughout this afternoon and two highlights: a Cinnabar moth on the Marshalling Yards was my first of the year and at last we have a Green Hairstreak on the Heath where we want them particularly. This contrary individual was spotted in a nettle patch but clearly focused on the Brambles behind so now it looks as though between now and the field trip on the 13th I need to check out every Bramble patch on the Heath as well as the usual Gorse and Broom. Suspect I might be busy next week. Here are the full details: 1 Holly Blue in my garden 1 on Whitton Road TW3 2EH 1 On Argyle Road TW3 2BE and 6 on the Holly hedge in St. Stephens Road TW3 2BW. Hounslow Heath: Comma: 2 Holly Blue: 3 Small Tortoiseshell: 4 Brimstone: 3 Peacock: 1 Orange-tip: 6 Green Hairstreak: 1 Green-veined White: 3 Small White: 1 Heath--Ex Golf Course: Peacock: 1 Comma: 2 Green-veined White: 1 Speckled Wood: 1 River Crane: Orange-tip: 1 Holly Blue: 2 Brimstone: 1 Marshalling Yards: Peacock: 2 Holly Blue: 3 Orange-tip: 8 Green Hairstreak: 4 Pevensey: Holly Blue: 6 Orange-tip: 3 Brimstone: 5 Speckled Wood: 1 Small Tortoiseshell: 1 Heath/Heather/Railway: Peacock: 1 Large White: 1 Brimstone: 1 Peter Gore

4 May This morning I went again to Rickneys looking for Grizzled Skippers without success but I saw a Latticed Heath moth, but there were plenty of Orange-tips and Green-veined Whites. On the south heath no Grizzled Skipper but as well as Orange-tips and whites several Peacocks and a Comma. However on the north heath I found a Grizzled Skipper over the fence on the railway side Steve Kiln
4 May Hounslow: Sunny on the outward stretch but mostly cloudy returning. Two quite high totals could reasonably be much higher: 8 Holly Blues on the Holly hedge in St.Stephens Road is undoubtedly lower than true numbers flying there today and at the start of the Heath walk numbers of Green-veined Whites were very high. I haven't included any I couldn't get close enough to for a definite identification but Small White and female Orange-tip are quite low. Nearly every white butterfly I look at is a Green-veined White. Details as follows: St.Stephen's Road TW3 2BW: Large White: 1 Holly Blue: 9 Hanworth Road TW4 5LQ: Brimstone: 1 Hounslow Heath: Holly Blue: 1 Green-veined White: 10 Orange-tip: 3 Brimstone: 1 Heath-ex Golf Course: Brimstone: 1 Holly Blue: 2 Orange-tip: 3 Peacock: 2 Speckled Wood: 5 Green-Veined White: 1 River Crane: Holly Blue: 1 Orange-tip: 1 Brimstone: 1 Marshalling Yards: Speckled Wood: 5 Orange-tip: 1 Green Hairstreak: 3 Green-veined White: 4 Peacock: 1 Pevensey: Green-veined White: 2 Small White: 1 Comma: 2 Holly Blue: 4 Speckled Wood: 1 Peacock: 1 Brimstone: 1 Heath/Heather/Railway: Peacock: 1 Comma: 2 Orange-tip: 1 and finally coming home 1 Holly Blue on Argyle Road TW3 2BE and slightly unusual an Orange-tip on Whitton Road TW3 2EG Peter Gore

Robert Callf
3 May I visited both parts of Bedfont Lakes CP. Nothing unusual on the north side, though there were good numbers of Brimstone (15+) and Green-veined White (15+), plus a few Speckled Woods, Orange-tips and both Large and Small Whites. I then moved to the south side of the railway, which is less manicured, more wooded and also less visited. At the gate, I was greeted by a Holly Blue sucking up minerals from the damp path, and then just inside the park entrance proper, I disturbed a female Green Hairstreak from the lush trefoil plants in the grass. Unfortunately the butterfly was soon lost in amongst the foliage. I walked to the railway and back, during which I saw at least 10 Holly Blues and a similar number of Green-veined Whites, plus Brimstones and Orange Tips. However, on the return leg, I spotted another Green Hairstreak. It was settled on a dogwood bush, and no amount of disturbance from me waving a camera could keep it away! I realised that it was laying eggs, and after a bit of searching I discovered some of the blue-green ova nestled in the flower buds Dave Miller
3 May 1 Brimstone - St Faiths Close, Hitchin TL19873030 David Inward
3 May Harpenden Common: 3 Orange-tip (all males); 2 Small Tortoiseshell; 2 Peacock (both rather worn); 3 Small White; and 3 Green-veined White. In my south Harpenden garden: 2 Orange-tip (1 male, 1 female); 1 Holly Blue; and 1 Small White David Hunt

3 May Hounslow: A very pleasant walk from mid-morning, mostly in sunshine,began with a Holly Blue in my back garden followed by a second one, a female, which flew from Privet to Rose bush as soon as I opened my front door. There was 1 Holly Blue on Whitton Road TW3 2EJ, 1 on Argyle Road TW3 2BE and 1 on St.Stephens Road TW3 2BH.

2 May Despite pretty horrible conditions at times, we found 1 Grizzled Skipper roosting at Rickneys close to the central foot path on a seed head but nothing at either Waterford North or South Pit over a four hour period - there are an awful lot of seed heads to check! Liz Goodyear

2 May At Grovelands Park near Church Hill entrance - 1 male Orange-tip and 1 Green-veined White at 14:42 hrs Robert Callf
1 May After nearly a week of cold grey and sometimes wet gloom, the sun shone this morning, and I had a lengthy look round my local patch at Sandwell Moor.

The overall tally was: Holly Blue - 20+; Green-veined White - 15+; Orange-tip - 10; Comma - 4; Large White - 3; Small White - 3; Speckled Wood - 3; Brimstone - 2; Peacock - 1 Dave Miller

Also seen were Green-veined White, Small White and a very brief visit by a Comma Liz Goodyear
1 May Hounslow: A Holly Blue in my garden this morning got the month off to an early start, with the following seen in a mix of cloud, sunshine, breeziness and rain: Hounslow Heath: Speckled Wood: 1 Green-veined White: 1 River Crane: Brimstone: 1 Marshalling Yards: Green-veined White: 2 Pevensey: Orange-tip: 2 Comma: 2 Heath/Heather/Railway: Orange-tip: 1 Peter Gore

25 Apr Speckled Wood at Stocking Pelham Andy Brown
25 Apr Hounslow: April showers today, leading to an odd-looking distribution of sightings and several species conspicuous by their absence. No doubt at all though that Speckled Woods are currently increasing. At the start of the walk the only butterfly seen was a Speckled Wood on the stretch of heath alongside the golf-course then: River Crane: Speckled Wood: 1 Orange-tip: 1 Green-veined White: 1 Marshalling Yards: Orange-tip: 6 Holly Blue: 1 Speckled Wood: 10 Pevensey: Green-veined White: 1 Speckled Wood: 4 Holly Blue: 2 Orange-tip: 1 Small White: 1 Heath/Heather/Railway: Speckled Wood: 1 Holly Blue: 1 and 1 final Holly Blue for today on Argyle Road TW3 2BE.

24 Apr 1 Holly Blue in my garden and 1 on Whitton Road TW3 2EG Peter Gore
24 Apr I found an Orange-tip roosting on honesty this evening in my Hertford garden Jenny Sherwen
23 Apr I went out locally in Stanwell Moor, and despite relative cloudiness and much cooler weather there were still a few things to be found, principally grounded Green-veined Whites: Green-veined White - 8; Small White - 2; Orange-tip - 3; Holly Blue - 4; Speckled Wood - 2 Dave Miller
23 Apr Hounslow: Cloudier this afternoon, Speckled Woods happy enough, Holly Blue not so much: Hounslow Heath: Green-veined White : 2 Orange-tip: 1 Peacock: 1 Marshalling Yards: Speckled Wood: 7 Orange-tip: 2 Small White: 1 Green-veined White: 1 Pevensey: Speckled Wood: 2 Peacock: 1 Holly Blue: 1 Orange-tip: 2 Green-veined White: 2 Comma: 2 Peter Gore

22 Apr A good selection of butterflies seen while pottering around at Nicholls Farm, Redbourn, including Orange-tip, Peacock, Comma, Small Tortoiseshell, Green-veined White, Small White and Large White. Lots of whites in particular enjoying the sunshine Peter Tallantire
22 Apr At Stanwell Moor: Brimstone 6; Small/GVW 14; Large White 4; Orange-tip 8; Holly Blue 30+; Peacock 6; Comma 5; Small Tortoiseshell 1; Red Admiral 2; Speckled Wood 8. Cooler again. After overnight rain, the paths were damp first thing, and the Holly Blues were down taking minerals in several spots. Their numbers continue to increase, and they were everywhere: seeing five or six at a time was quite common. One individual became quite tame and happily sucked sweat from my finger. I saw the first Large Whites of the year: a female appeared and was almost immediately set upon by a male and the pair coupled in very short order. I also came across a fairly new-looking Red Admiral, possibly a recent immigrant or maybe locally hatched Dave Miller

22 Apr Hounslow: Overnight rain meant a high river and a few more puddles but sunshine all morning led to a further increase in numbers although less variety. Holly Blues lead the way: 2 in my garden, 3 on Whitton Road TW3 2EG, 2 on Argyle Road TW3 2BE and 2 on the Holly hedge in St.Stephens Road TW3 2BW then Hounslow Heath: Speckled Wood: 2 Brimstone: 3 Small Tortoiseshell: 2 Orange-tip: 2 Heath-- Ex Golf Course: Comma: 2 Orange-tip: 2 Brimstone: 1 Holly Blue: 1 Large White: 1 Green-veined White: 1 River Crane: Orange-tip: 2 Marshalling Yards: Peacock: 3 Orange-tip: 6 Speckled Wood: 5 Holly Blue: 2 Small Tortoiseshell: 1 Brimstone: 1 Green-veined White: 2 Pevensey: Small White: 1 Holly Blue: 7 Orange-tip: 3 Brimstone: 2 Heath/Heather/Railway: Holly Blue: 2 Brimstone: 1.

21 Apr Hounslow: Good morning sunshine today and good butterflies with two firsts: my first Green Hairstreak of the year lived up to its scientific name settling on Bramble, a second one later was in a more usual setting on Broom, both on the Marshalling Yards. As I was heading for the tunnel on the way back a Painted Lady surprised me although on reflection it occurred to me I've been seeing Large Whites (and probably understating their numbers slightly) and Red Admirals over these last few days so perhaps we have a few migrants here or passing through. Here are the full details: Argyle Road TW3 2BE Holly Blue: 2 Hounslow Heath: Orange-tip: 2 Small White: 2 Holly Blue: 1 Large White: 1 Speckled Wood: 1 Red Admiral: 1 Green-Veined White: 3 Small Tortoiseshell: 3 Brimstone: 1 Heath--Golf Course: Holly Blue: 2 Orange-tip: 2 Brimstone: 1 Speckled Wood: 1 River Crane: Orange-tip: 1 Comma: 1 Holly Blue: 2 Marshalling Yards: Peacock: 2 Comma: 3 Holly Blue: 3 Speckled Wood: 3 Orange-tip: 4 Green Hairstreak: 2 Painted Lady: 1 Pevensey: Small Tortoiseshell: 1 Orange-tip: 3 Green-Veined White: 1 Holly Blue: 4 Small White: 1 Speckled Wood: 1 Comma: 1 Heath/Heather/Railway: Brimstone: 1 Peter Gore

18 Apr First sightings in our garden of Orange-tip(female) and Holly Blue (male) at Bernards Heath, St Albans David Utting
18 Apr On a long walk today from Ivinghoe Aston to Ivinghoe Beacon, Ashridge Visitor Centre, Norcott Hill, Dudswell, along the Grand Union to Bulbourne then down the Wendover Arm to Wilstone and back, I saw Holly Blues (my first of the year), an Orange-tip (ditto), Small and/or Green-veined Whites (ditto), Brimstones, Peacocks, Small Tortoiseshells, Commas and (80% certain it was on the other side of the canal) a Red Admiral. All were seen in Herts but only Brimstones, Peacocks, Small Torts and Commas in Bucks, probably because of timings (start and end of the walk). Now I am cream crackered, but it was worth it Rikki Harrington
18 Apr On a glorious warm and sunny day at Stanwell Moor, I went out and about early before the butterflies became too energetic and I became the opposite! Brimstones were the most numerous species again, with well over a dozen seen overall. Today was also a big day for Holly Blues, and I came across around ten in various spots, including several sucking up minerals from damp patches on the path. I also saw several Commas laying eggs on the the young nettle plants.
A rough tally of species: Brimstone - 15+; Holly Blue - 10+; Small/GV White - 10+; Peacock - 10+; Orange Tip - 7; Comma - 5; Small Tortoiseshell - 1

18 Apr Female Emperor moth (Saturnia pavonia) at Therfield heath (Church Hill) today Chris Benton
18 Apr Female Brimstone nectaring on Bluebells in my Hatfield garden today John Moss
18 Apr In a country lane not far from Flaunden, Flaunden Lane at least two Peacock butterflies along the Nettles and hedges in late afternoon sun Elizabeth Debenham
18 Apr Harpenden Common: 10+ Small Tortoiseshell, most still in the nettle bed area but others dispersed across the common; 1 male Brimstone; and swarms of Grey Gorse Piercer (Cydia ulicetana) around (where else) the gorse bushes. The Comma and Peacock butterflies from yesterday were nowhere to be seen and had presumably dispersed with the warmer and less windy conditions David Hunt
18 Apr 1 Brimstone - St Faiths Close, Hitchin TL19873030 David Inward
18 Apr Despite the warm weather, saw relatively few butterflies on the London Borough Hillingdon & Harrow transects. Did see my first Speckled Woods at Roxbourne Rough and Lake Farm and my first Green-veined Whites at Minet Country Park, all a couple of weeks late this year Paul Busby
18 Apr There were good numbers of Brimstone on the wing today at Purwell Ninesprings and our first Holly Blue of the year! Jenny Sherwen
18 Apr Hounslow: Warmer and sunnier, inevitably with lots of butterflies including 4 year firsts: Hounslow Heath: Holly Blue (1st): 1 Peacock: 2 Small Tortoiseshell: 1 Heath--ex-Golf Course: Comma: 1 Orange-Tip: 1 Green-Veined White (1st): 2 Peacock: 1 River Crane: Red Admiral (1st since February): 1 Holly Blue: 1 Comma: 1 Small Tortoiseshell: 1 Marshalling Yards: Comma: 1 Orange-Tip (1st): 3 Brimstone: 3 Peacock: 4 Pevensey: Comma: 4 Brimstone: 5 Holly Blue: 2 Small White (1st): 1 Heath-Heather/Railway: Small Tortoiseshell: 1.
The highlight involved the Green-veined Whites. I first saw a male Orange-Tip which promptly got into an aerial duel with a white butterfly. This soon ended with the white flying on in front of me quickly joined by another white, both dropping out of sight. As I drew next to them - five yards at most - they rose again, now a mating pair of Green-Veined Whites, the female towing the male in the usual fashion to plants at eye-level. 'Courtship' acceptance and mating commencement all in a matter of seconds it seemed. Both looked very fresh with conspicuous veining

18 Apr My first butterfly of 2018, in warm, sunny, Kings Langley this lunchtime was a Holly Blue!! Elizabeth Debenham
17 Apr Sunshine arrived in the middle of the day, and so did the butterflies. A walk around my usual route at Stanwell Moor showed that the Orange Tips in particular are well underway. Overall, I saw seven, plus seven Brimstones, five Peacocks, five Commas, a Small Tortoiseshell and several Whites, including my first Green-veined White of the year. There was at least one other, plus three Small Whites as well. Right at the end of the walk I spotted another new species for the year - a Holly Blue flying around a large Holly tree Dave Miller

16 Apr Hounslow: Cloudy conditions today with few butterflies and I had to wait until the Pevensey loop before I felt myself rewarded with my first Speckled Wood of the year, a very fresh looking individual. A Comma was the only other butterfly identified. With future Hairstreaks in mind I'm looking for both Elm and Blackthorn. Not so good for the former but far more of the latter than I'd remembered even effectively on my walk as well as elsewhere on the heath and golf course. I foresee quite a lot of peering at twigs in the autumn and winter! Peter Gore
16 Apr 1 Adela reaumurella SW edge of Rough Lot, Trent Park (TQ 284975) this afternoon at 12:50 BST - my first of the year! 1 Double-striped Pug at ASDA Southgate Robert Callf

A walk around my local patch at Stanwell Moor in glorious warm sunshine was blessed with good numbers of butterflies. The highlights were the three Orange Tips, the first of the year. Totals for a couple of hours gentle ambling: Brimstone 9 (including 3 females), Small Tortoiseshell 8, Peacock 5, Comma 4, Small White 3, Orange Tip 3 Dave Miller

Baldock Road Recreation Ground, Letchworth - 1 Brimstone at TL23113261 David Inward
14 Apr Hounslow: More sunshine at last and although I failed to get close enough to several whites, given glimpses of black wing-tips it's likely that at least one of the two smaller whites (three with female Orange-Tip) is now flying here. Here are the butterflies I could identify: Hounslow Heath: Peacock: 2 Small Tortoiseshell: 4 Brimstone (f):1 Heath--Golf Course: Peacock: 2 Marshalling Yards: Comma: 4 Brimstone (m): 3 Peacock: 2 Pevensey: Comma: 1 Peacock: 1 Heath-Heather, Railway: Peacock: 1.

March

Date Description Recorder
26 Mar I was just beginning to give up hope of seeing a butterfly in March when at last a male Brimstone put in an appearance flying along the top of the bushes that shield Argyle Road (TW3 2BE) Hounslow from the railway. There were two more sightings of unidentifiable dark butterflies probably Red Admirals,one on the Marshalling Yards,one on the Pevensey Loop; this representing a doubling of that category to date. The earlier one last week I thought more likely a Peacock. Moths have been about the same with three separate sightings of single likely Orange Underwings flying near the tops of Silver Birches, also on the Marshalling Yards mid March to March 22nd Peter Gore
26 Mar A male Brimstone and 2 Small Tortoiseshell in Fieldfare way Royston today Laurence Drummond
26 Mar 2 male Brimstones today: One at Little Mole wood, Bengeo and one at Goldings, Waterford Chris Benton
26 Mar A lovely sunny morning and a walk around my local patch near Heathrow started with a Small Tortoiseshell right outside the front door. An hour or so of walking produced four Peacocks, a Brimstone and a Comma to add to the total. Finally, on the way back, I found a freshly emerged male Small White nectaring on a pussy willow - see photo on right. Eight butterflies of five species - not bad considering the season is only just underway Dave Miller

February

Date Description Recorder
26 Feb On a cool grey day, I saw a Small Tortoiseshell flying around the roof of a house in Aldbury Charlie Jackson
18 Feb I saw 1 Red Admiral today near Bramfield (TL282164) Jenny Sherwen
18 Feb St Albans: My first transect of the year, looking for butterflies hibernating in my shed. I recorded a total of 19 Small Tortoiseshells, all fast asleep. The numbers were down by three compared to my last visit in October. I doubt that any have yet flown so the fall in numbers is most likely due to predation by spiders. Another possible cause is the butterflies changing position - they tend to shuffle around over time, gravitating towards the darker recesses. This can make them harder to spot, even with the aid of a torch. Also recorded on the same site, one Large White pupa, which I found inside my house over Christmas and moved to a cooler spot so that it doesn't hatch too early Malcolm Hull
17 Feb 1 Red Admiral (briefly) in my Ware garden this morning Liz Goodyear
12 Feb Hounslow: Ice on puddles across the site and temperatures in single figures but some sunshine and my second Red Admiral of the year. This was on the Heath at the junction of the three tetrads and managed at least a few moments in each of them flying quite energetically for a coldish day in February Pete Gore
12 Feb Red Admiral in garden NW Bishop's Stortford. 12:30 pm Jim Fish
2 Feb A Red Admiral under the eaves outside our St Albans house at 9:30 am - it was awake early! Mandy Floyd

January

Date Description Recorder
31 Jan 1 Common Quaker at Oakwood Station above stairwell - spring is on the way!? Robert Callf
25 Jan Report from Butterfly Conservation: A Speckled Wood flew across Bow Creek. Wasn't a very early emergence, as it looked really tatty. It must have been one of last year's that had somehow hung on  
25 Jan Although temperatures were still quite low, bright afternoon sunshine was perhaps sufficient to encourage a Red Admiral to fly on the Marshalling Yards during today's walk Pete Gore
25 Jan First butterfly sighting of 2018 for me, Red Admiral on Muswell Hill Broadway reported on facebook Dee Cullen
19 Jan I know it's sunny today but it's still badly cold and there's a bit of northerly in the west wind. So I was surprised, though pleasantly so, to see a pristine Red Admiral sunning itself on one of our south-facing window sills in Stepney at 12.30 Keir Mottram
18 Jan A Red Admiral flying and basking at 11:30 hours in a front garden in Brent, NW9, grid ref TQ 207 867. Also in NW9, 450 metres away at the end of the same road, an unidentified Nymphalid glimpsed in flight at 13:15 hours at the Welsh Harp Environmental Education Centre, grid ref TQ 208 871 Colin Everett
17 Jan A Nymphalid flew across the road at the entrance to Shingle Hall, Trimms Green near Sawbridgeworth at 12.40, most likely a Small Tortoiseshell Laurence Drummond
17 Jan White-letter Hairstreak eggs are waiting to be found at the moment! A visit to SW London today found eggs on elm in the London Boroughs of Ealing (TQ28); Hounslow (TQ17); Richmond and by the Thames in Sunbury (Spelthorne DC) (TQ12) at 6 sites! Liz Goodyear
Andrew Middleton
10 Jan Whilst walking along the Grand Union Canal Wendover Arm today I saw a fine male Brimstone (SP912130). It was bright sunshine and 8 deg. C., well below the normal flight threshold. Anyway, a wonderful early 'spring' moment amongst the gloomy days, even though it may be two months before I see another. I have been recording firsts since 1988 and my previous earliest was 13th Feb (1998) Richard Harrington
2 Jan Report from Butterfly Conservation HQ - at 10 am, outside the vets I work in Connaught Street, London W2, a Red Admiral fluttering around. Couldn't believe it! Catherine Beazley
