Despite four recent visits this is the first Small Blue I have seen on this site, however another visitor I met said he had seen one earlier today on another part of the site Roger Millard
21 May I have seen only one Large White this year but I was amazed to find 3 clusters of yellow eggs 1-2 metres high on railings (facing east) surrounding a kissing gate by the Aston End Brook, south-east of Ridlins Wood, Stevenage. Are they really Large White eggs? I can't think what else they can be but I am happy to be corrected! Peter Clarke
21 May Hounslow. Mostly sunny with a good selection of butterflies although Whites seem to be fairly poor at present: Holly Blue: 12, Peacock: 4, Speckled Wood: 4, Green-veined White: 1, Orange-tip: 3, Common Blue: 3, Small Copper: 4, Brown Argus: 4, Small Heath: 4, Small White: 1, Green Hairstreak: 3, Brimstone: 1 Peter Gore

20 May While out on my local patch at Stanwell Moor, I found my first Large Skipper of 2019 Dave Miller
20 May A single Speckled Wood in Cutthroat Wood, Hillingdon, looking back over the last couple of years, I am seeing less Speckled Woods this Spring at the usual woodland sites in Hillingdon, hopefully it will improve Paul Busby
20 May 1 Holly Blue - St Faiths Close, Hitchin David Inward
20 May Hounslow. After a blank day yesterday a little more sun today and the following were seen: Holly Blue: 5, Orange-tip: 6, Peacock: 7, Speckled Wood: 2, Brimstone: 1, Common Blue: 1, Small Copper: 1 Peter Gore

19 May We were joined by David Kirk, chairman of the Box Moor Trust and three other branch members for the walk around the lovely Bovingdon Brickworks managed by the Box Moor Trust. Overnight rain meant everything was a bit damp, and despite the forecast saying there would be some sunshine on arrival there was not. However, this proved a great bonus as it meant the resident Dingy Skippers were still roosting and a pre-walk search located several for everyone to see and take photos. A total of 6 were found in the meadow adjacent to the car park. As we set off it became apparent that the sun was trying to shine, which it did relatively weakly for the remainder of the walk. This meant that the Dingy Skippers were beginning to come off their overnight roosting seed heads but were as a result not flying very strongly or simply basking on the bare ground. A further 9 were found including a pair having quite a battle in the bottom of one of the pits. Also recorded were 3 Brown Argus, 3 Orange-tip, 2 Common Blue, and 2 Cinnabar moths. It was lovely to hear a cuckoo calling nearby and one more distant. Although the butterfly count was quite poor, everyone went home quite content with what they had seen.
Earlier we had made a visit to the A41 Bourne End slip road but were unsuccessful in finding any roosting Small Blue, however we did see 2 roosting Brown Argus and 2 Small Yellow Underwings. The Kidney Vetch though appears to be doing very well although not in flower yet

19 May Visited Coppetts Wood in Barnet between 9.45 and 10.30 in rather overcast conditions, only sighting were two Speckled Wood and 1 Holly Blue.
Walked along Tunnel Gardens from 11.00 till 1.00 photographing the flowers, some well camouflaged dock bugs on dock leaves and in the process I saw 5 Holly Blues, 3 Speckled Wood, three Green-veined White and was lucky enough to find a male Orange-tip who posed nicely on wild carrot and garlic mustard

19 May Small Tortoiseshell caterpillars spotted on the nettles on my St Albans Allotment. Most were in a series of clusters, with a few larger individuals beginning to disperse. Attempted a count, which was not easy and got to 300 individuals, which is more than I see at this spot most years. See video on Malcolm's twitter Malcolm Hull
18 May Off transect records for Minet Country Park, Hayes (TQ109800) - male Common Blue, Brown Argus, two female and one male Orange-tip and a Holly Blue Paul Busby
18 May 1 Small White near Allotments at Vicarage Farm, Enfield at 12:21 hrs, 2 Mother Shipton and 1 Common Carpet at Vicarage Farm, Enfield (TQ 3097) - the latter a first for the year, 1 Green-veined White at Parkside Farm, Enfield (TQ 2998), also here 1 female Orange-tip and 1 Small Tortoiseshell, 1 Silver Y at Parkside Farm - my first for the year, 1 Speckled Wood at Park Farm, Enfield, also here 1 Peacock and 1 Green-veined White, 1 Small Copper near Ride Wood, Trent Park at 14:37 hrs, 4 Brown Argus, 1 Small Copper and 5 Small Heath at Vicarage Farm, Enfield near Shaws Wood (TQ 2997) Robert Callf
17 May Of interest the micro moth that we couldn't identify on our visit to Hexton on 15 May proved to be a serious rarity, thanks to Ben Sale for confirming its identity. It was Anania fuscalis. See Ben's moth blog for records in 2015 and 2017 Liz Goodyear

16 May I visited the northern part of Bedfont Lakes Country Park, and saw the following: Holly Blue 8, Brown Argus 6, Green-veined White 3, Common Blue 3, Green Hairstreak 3, Brimstone 2, Peacock 2, Orange-tip 2, Small Heath 1, Speckled Wood 1.
The Green Hairstreaks were widely separated, with the one shown in the photo being within sight of the visitor centre. The Common Blues included a beautiful blue female, more silver than blue

16 May This afternoon we were walking round the Halsey Field in Gadebridge, Hemel Hempstead (TL042088) with some friends, when we had a really good view of a Green Hairstreak fluttering around, then landing on a Dogwood bush near the southern perimeter fence. Sightings of a Green Hairstreak were made this time last year on the site, so it looks very possible that the species is now breeding on the field. I didn't manage to get a good photo of the hairstreak as it was high in the bush, but I did manage a somewhat out of focus photo of the Small Yellow Underwing which I saw on Sunday 12th May at the bottom of the slope on Halsey field, as I was walking the transect Christine Ridley
16 May 1 Holly Blue female - St Faiths Close, Hitchin David Inward
16 May Hounslow. Cloud and breeziness reduced numbers a little but still plenty to see: Peacock: 5, Speckled Wood: 2, Green-veined White: 3, Common Blue: 1, Large White: 1, Orange-tip: 3, Holly Blue: 5, Small Heath: 4, Brimstone: 3, Small Tortoiseshell: 1, Brown Argus: 2, Small Copper: 1 Peter Gore
16 May 1 Holly Blue at Enfield Chase Station (TQ 321 966) at 11:21 hrs, 1 Holly Blue at Whitewebbs Park (TQ 321 998) at 12:54 hrs, 3 Speckled Wood at Whitewebbs Park (TQ 329 997), 1 Speckled Wood, 1 male Brimstone and 1 male Orange-tip at Archers Wood, Enfield (TQ 333 992), 1 female Holly Blue at Forty Hall CP, Enfield (TQ 336 991) at 14:35 hrs, 1 female Orange-tip and 1 Speckled Wood at Forty Hall CP (TQ 337 984). 1 Small Dusty Wave at Gordon Hill Station this morning - my first of the year Robert Callf
16 May The first Common Blue of the year - a female - was in the north west corner of the cricket pitches at Alexandra Palace (TQ300899) this morning, along with Brown Argus and Small Copper. Elsewhere on the Palace there were Brimstone, Holly Blue, Small White, Orange-tip and Peacock Gerry Rawcliffe
15 May At Water Lane , Watford found Orange-tip x 4, Brimstone x 2, Common Blue x 1, Common Carpet moth x 1. At Fishers Field afterwards seeing Brimstone x 3, Peacock x 2, Holly Blue x 1, Common Blue x 1 David Gower
15 May We went north and first visited Hexton Chalk Pit, arriving mid-morning so with the glorious sunshine everything was seriously on the wing! Immediately a small pyralid moth got our interest but we have yet to identify it. As we walked through the pit, it became obvious that there were serious numbers of Dingy Skipper flying - in some places one per square metre! It was impossible to get an accurate count but we reckon a minimum of 50 were seen. As we walked through the pit, we encountered a Green Hairstreak on the ground and then watching the various sycamore trees at the top end of the site we watched numerous duels and chases and at times they were interacting with the Holly Blue in the same area. Again they were hard to count but we think we probably saw about 9. Also seen during our visit were a single Small Heath, several Brimstones and on the adjacent field an Orange-tip. Day-flying moths included Small Purple Barred, Small Yellow Underwing, Pyrausta nigrata and aurata, and Burnet Companion.
We then went to Hillbrow at Letchworth but no Small Blue were encountered despite the Kidney Vetch appearing to be doing very well although nowhere near flowering. The majority of butterflies seen were either Orange-tip or Brimstones but we did see 2 Brown Argus as well as Holly Blues. Day-flying moths included Latticed Heath, Burnet Companion, Mother Shipton (photo), Cinnabar and Small Yellow Underwing.
Finally we visited a field opposite the entrance to the Wilbury Hill Carpark. Here butterflies were far more numerous with Brown Argus, Small Heath, Small Copper, Brimstones and Orange-tips flying. Day-flying moths included Latticed Heath and Small Yellow Underwing

15 May 1 Brimstone male, 1 Holly Blue, 1 Orange-tip male - St Faiths Close, Hitchin David Inward
15 May Oakwood Park (15:20 - 16:00 hrs) - 1 male Brimstone, 3 Holly Blue and 1 Small Copper and 10+ Mother Shipton were very active & restless. 1 Small White and 1 Holly Blue at Prince George Ave., N14 (TQ 299 956) at 16:05 hrs and 1 Peacock settled at Boxer's Lake, Enfield at 16:15 hrs Robert Callf
15 May Hounslow. Two Small Heaths completed our local list of spring butterfly species (17) on another sunny day. One other highlight and one oddity: a Green Hairstreak on one of the burnt areas moved purposefully from one little patch of regenerating Bramble to another.I didn't manage to spot any eggs or actual laying but it did look as though that was what the butterfly had in mind. What two butterflies seen shortly after had in mind was something else altogether, a Small Tortoiseshell and a Peacock spent quite a bit of time together in a manner most unlike these two species. Although never actually mating, at one point they were both on my left foot -a double first for my left foot there and a little later the presumed male Small Tortoiseshell was resting at right angles on the closed wings of the Peacock. I left them to it, whatever 'it' was! Here are the full details of sightings: Holly Blue: 9, Speckled Wood: 1, Green-veined White: 2, Small Copper: 5, Brimstone: 5, Common Blue: 1, Comma: 1, Red Admiral: 1, Orange-tip: 9, Peacock: 5, Green Hairstreak: 2, Small Heath: 2, Brown Argus: 1, Small Tortoiseshell: 1, Large White: 1 Peter Gore
14 May Seen in Bushey garden: Holly Blue x 5, Peacock x 1, Comma x 1 David Gower
14 May This afternoon in my St Albans garden - Orange-tip, Green-veined White, Brimstone, Holly Blue, Mint moth and longhorn moth Malcolm Hull
14 May A probable Large Tortoiseshell or Scarce Tortoiseshell just N of Bovingdon at lunchtime. I flushed the butterfly next to a footpath and was struck by its size (similar to Painted Lady) and colour (pale orange-brown); when I very briefly glimpsed the markings it was obviously a tortoiseshell but the flight was very different - strong with frequent glides, like a large fritillary. It was also very skittish and I could not relocate it once it had flown off into an adjacent field. The location was the footpath between Duckhall Farm and Bourne End Lane near the karting track, where the path changes from a NE to NNW direction and a grassy field opens out on the east side, about 20 metres N of the end of the hedgerow, at grid reference TL 01418 04468. I'd welcome any attempts by other observers to re-find it. Nearby there was a Small Copper at the entrance to Little Hay Golf Course (TL 0192 0465) Colin Everett
14 May Alexandra Palace's (TQ303898) first Brown Argus of the year was found in the south east corner of the park, somewhat away from where it was expected! Also Small Copper, Orange-tip, Brimstone, Speckled Wood, Holly Blue, Peacock, Small White and Green-veined White seen but surprisingly no Small Heath which have been a feature in recent days Gerry Rawcliffe
14 May 1 Brimstone - St Faiths Close, Hitchin David Inward
14 May Hounslow. A very good sunny walk with four species seen for the first time this year.

Miles Attenborough
11 May Spring Meadow Farm, White Hill Lane, Whelpley Hill, near Bovingdon - 4 Dingy Skippers in this 8 acre wildflower meadow, created from a former potato field. The Dingy Skippers were in two courting couples, which spent ages flying close together twiddling round each other. Luckily one eventually landed for a photo. Also in the meadow were Orange-tips, Green-veined Whites, Peacocks, a Brimstone and a Small Tortoiseshell. Lindsay McRae also saw a Small Copper.
This farm straddles the Herts/Bucks border and while the buildings are all in Bucks, the 8 acre wildflower meadow is all in Herts. Note it is a private site, the landowner will allow access by prior arrangement, contact me for details.
A41 Bourne End junction - stopped at this Small Blue site on the way home, but no sign that they have yet emerged at this location

10 May A couple of Red Admirals, and it occurred to me I haven't seen many this year. Also saw a Small Copper, Brimstones, a Green-veined White and many Small Whites, and Speckled Woods on my new transect walk in Alexandra Park Dee Cullen
9 May 1 male Orange-tip at Parkside Farm/Res., Enfield (TQ2998) at 11:25 hrs and 1 Speckled Wood at Ash Wood, Enfield Chase Robert Callf
8 May This was our first opportunity to look for Grizzled Skippers and the 'damp' weather didn't deter us, even the thunder and lightning didn't stop us although a very soggy notebook was a bit of a nuisance.
We started at Frogmore just after 10.30, it was raining and the temperature didn't go much above 10 °C. In total we found exactly 10 roosting Grizzled Skipper distributed throughout the site. We believe 7 were male and 3 female with a choice of seed head being Perforate St. John's Wort (3), Knapweed (4), Bramble (2) and one unidentified stem! We looked at the hawthorn and flowering Forget-me-not but there really was too much to check. No eggs were found but with the wet weather and rain drops looking like eggs it wasn't the right day to start looking. Also found roosting were 8 Brown Argus, 1 Small Copper and 1 Toadflax Brocade moth. We finished just after 12.30.
We then went to Rickneys Quarry and started walking around the site at 1.20 and although there were moments of brightness which made at least one Grizzled Skipper open its wings, the majority of the afternoon was spent walking around in the rain. Just at the end the sun came out and some of the Grizzled Skippers became active but we couldn't count these. We left around 4.30 just before a torrential downpour. Totals here were 12 Grizzled Skipper, with we believe 7 males and 3 females and the remainder not confirmed. Here the seed-heads being used were Carline Thistle (4), Bramble (4), Perforate St. John's Wort (3) and one further individual on the move. Also recorded were 6 Cinnabar Moths, 1 Latticed Heath moth, 2 Small Copper and 21 Brown Argus. Also noted was a Pyrausta species of moth. We did not record any roosting Small Heath which we expected to do.
We also looked at one of our favourite elm trees with really low easy to check branches. On inspection and only during a matter of minutes and below head-height we counted at least 13 White-letter Hairstreak caterpillars, all now on the leaves and only one more mature with one also we thought was predated. There were several other caterpillars and a lot of larval damage on the elm. We hope to identify the caterpillars in due course

1 May This morning, I visited Bedfont Lakes Country Park. I started at the southern, less well-known section, and in within a few yards of entering the main part of the park I had seen my first Green Hairstreak down on the grass. By the time I left, I had seen seven altogether: four in this area, one close to the railway, and two more on the far side of the lake. They must be spread across the whole site. Also seen: Holly Blues (9), Speckled Woods (8), and Peacocks (2).
There being no link between the two sections, I drove round to the northern part of the park, and found two more Green Hairstreaks close to the railway. The sun was getting very hazy, and the only other sightings were: Holly Blue (1), Peacock (2), and Green-veined White (4).
Returning home, with the sunshine getting stronger again, I walked my usual circuit at Stanwell Moor. Holly Blues were everywhere, as they have been for a while now - 23 seen. There were also Orange-tips (8), Brimstones (4), Peacocks (2), Green-veined White (7), and Small White (1). I also found a shiny new Small Copper (my second here this year), and more of a surprise, a new male Brown Argus. This was my first of the year anywhere

29 Mar Two separate male Orange-tips: one at Aldbury Nowers (SP 957 135) and one at Berkhamsted Common (TL 005 093). For comparison, back in 1995 a male I saw on 3rd April was the earliest ever for the county in what was then a remarkably early spring; multiple March sightings (as this year) would have been unthinkable even a few years ago.

29 Mar St Albans - 80% of the Small Tortoiseshells which were hibernating in my shed have now left. 67% of the Peacocks are now in hibernation. One of the ST's had not gone far and was found flying around inside my car parked close by. Another was found dead, shrouded in spiders web. Later in Greenwood Park there were many Peacocks, Small Tortoiseshells and Brimstone in flight. Finalised arrangements for the construction of the chalk bank, hopefully we will see Small Blues in this location within a few years Malcolm Hull
28 Mar At Northaw Great Wood this afternoon - 2 Orange/Light Orange Undwering including one disturbed from the ground at 13:11 hrs and another in flight at 13:45 hrs, 3 Peacock and 1 Comma. Male Brimstone seen from train window just N of Crews Hill Station (TL308004) at 12:05 hrs Robert Callf

25 Mar A male Orange-tip in my Rickmansworth garden Anna Marett
25 Mar Hounslow: Smaller numbers today with the male Brimstones vanished again, perhaps on a quest for the still missing females. 5 Peacocks and 1 Comma were the only sightings Peter Gore
25 Mar I walked my WCBS in Northaw Great Wood early afternoon and saw three Commas. Two were scuffling high up and eventually landed to sunbathe. The third in a different area was basking in a sunny spot Dee Cullen
25 Mar On another tour of my local patch at Stanwell Moor at near enough the same time as on the 24th and in similar conditions, my first two sightings were of new species for the year. First came a Holly Blue flying around ivy near the River Colne, followed immediately by an Orange-tip sunning itself near the river bank. This was disturbed by a Red Admiral, which then basked on the bridge over the river. Overall, in addition I saw another Holly Blue, plus four Small Tortoiseshells and eight Peacocks, including a pair courting high up in a flowering prunus Dave Miller
25 Mar 1 Small Tortoiseshell resting on stinging nettles by the Colne Rebecca Palmer
25 Mar At Trent Park - 2 Peacock (1 edge of Moat Wood, 1 'Old Golf Course') and 1 Comma edge of Moat Wood Robert Callf

24 Mar I saw a Camberwell Beauty in Muswell Hill, London N10. It landed on my friend's back so I was able to look at it for a couple of minutes before it flew away. What a beautiful butterfly! (Very close to the other 2 sightings in north London. Peter C) Jean Burrow

24 Mar In Bengeo garden: Brimstone male, Comma, Holly Blue & Peacock Simon Knott
24 Mar Brimstones common on the Ashridge Estate today, with 1-km grid square totals as follows (but probably some duplication of wandering individuals): 4 in SP 9612 (including 2 simultaneously); 3 in SP 9712; 1 in SP 9711 and 1 in SP 9611. All were males and were seen between 10:20 and 14:20 hours Colin Everett
24 Mar A warmer than forecast, sunny Spring day and decided to visit Hillingdon transects, where I saw 20+ butterflies, Peacocks accounted for half of them with some Small Tortoiseshells, Commas, male Brimstones and my first Holly Blue of the year in the small copse at Lake Farm Country Park. I think it shows the value of starting the transect early if conditions are within limits Paul Busby
24 Mar 1 Brimstone - Meadowbank, Hitchin (TL196300), 1 Brimstone - Railway Station, Hitchin (TL194297) (possibly the same individual) David Inward
24 Mar An early afternoon walk in Fairlands Valley Park and the surrounding woods resulted in 36 butterflies: 11 Brimstone, 15 Peacock, 6 Comma, 2 Small Tortoiseshell and 2 Small White. The Peacocks and Small Whites were my firsts of the year Peter Clarke
24 Mar Hounslow: Ideal spring weather for butterflies so not surprising to find numbers of sightings well into double figures. These included our first Orange-tip of the year, one day earlier than 2017's early sighting. Here are the details: Brimstone: 8 Comma: 4 Peacock: 6 Orange-tip: 1 Small Tortoiseshell: 1. All the Brimstones above were males Peter Gore
24 Mar 1 male Brimstone near Hadley Road at Vicarage Farm, Enfield (TQ 30 97) at 11:51 hrs, 1 Peacock edge of Duncan's Wood, Enfield Chase (TQ 287 985) at 12:38 hrs, 1 Peacock at Plumridge Farm, Enfield near Ash Wood (TQ 283 985) and another nearby at Park Farm, Enfield, 1 male Brimstone edge of Moat Wood, Trent Park (TQ 287 978) at 13:17 hrs and 1 Peacock here also, 2 Comma together edge of Ride Wood, Trent Park (TQ 289 976) at 13:26 hrs Robert Callf

One of the remaining Tortoiseshells in a completely different position, possibly having left the shed and then returned? The positions of the other 8 are unchanged Malcolm Hull
21 Mar A Peacock at Otterspool near Aldenham, grid ref TQ 1290 9909 Colin Everett
21 Mar Pleased to find a Small Copper larva survived the winter in my Stevenage garden Peter Clarke

19 Mar This morning I saw 2 male Brimstones on my way back from Stevenage Old Town, one along Walkern Road, just before the cemetery and the other along the cycle path between Grace Way and Lonsdale Road, Stevenage on the climb up towards Hampson Park Don Gregory
19 Mar On the Ashridge side of Berkhamsted Common I observed a mating pair of Orange Underwing moths. Photographs and a film are on my Facebook page Colin Everett
19 Mar Whilst tidying up one of the borders in my Bishop's Stortford garden I found a Lesser Broad-bordered Yellow Underwing(?) caterpillar on the ground. (Photo on right - can anyone confirm or otherwise the id? Peter C.) Bob Clift
19 Mar At Whitewebbs Park (TQ 323 991) along Cuffley Brook this afternoon 12:20 - 12:22 hrs - 1 male Brimstone, 1 Peacock and 1 Comma Robert Callf

17 Mar I found quite a few Purple Hairstreak eggs on Oak buds in Northaw Great Wood (TL2804). I saw adults last summer there while doing the WCBS count so figured it was worth having a look Dee Cullen
9 Mar A single pristine Comma around mid-day in our Pinner garden in bright but blustery conditions Tony Porter
9 Mar First time I have ever seen a Camberwell Beauty - at Winchmore Hill Station at 1205. (Filomena Jones reported a sighting at Finchley Central N3 in February - unsure of exact date. Could it be the same specimen being about 5 miles away? Peter C) Robert Bourton
9 Mar 1 Orange/Light Orange Underwing seen in flight at Oakwood Park (TQ 300 952) this afternoon at 14:35 hrs Robert Callf
2 Mar Just one Red Admiral at the weekend in Bushey. Spotted from the kitchen window at lunchtime! Rebecca Palmer
1 Mar St Albans Shed - Pleased to report that today's shed transect produced a full complement of 13 Small Tortoiseshells and 3 Peacocks. None have been seduced out of hibernation by the warm February weather. Judging by the miserable forecasts for the next two weeks, they have been wise to stay asleep indoors Malcolm Hull

One of the Red Admirals was egg-laying close to the River Colne Dave Miller

25 Feb Brimstone at Waterfields Playground, Watford. Small Tortoiseshell and Red Admiral in Park Avenue, Bushey Rebecca Palmer
25 Feb Hounslow: More sunshine and more Brimstones. I've slightly reduced the number of actual sightings to allow for the possibility of highly active males (which they all are) getting counted twice so it's Brimstone: 7 Small Tortoiseshell: 1 Peter Gore
25 Feb Hertfordshire County Offices car park adjacent to Grand Union Canal at Apsley (TL066047) - 3 Brimstone Robert Harris
25 Feb A female Brimstone, a Comma and at least two Red Admiral and two Small Tortoiseshell seen at Alexandra Park (TQ302902) Gerry Rawcliffe
25 Feb One male Brimstone in my south Harpenden garden David Hunt
25 Feb Another wander round my local patch at Stanwell Moor a bit earlier in the day. Three Small Tortoiseshells, only one of which was one of those seen yesterday. Only a couple of Brimstones (delayed by the overnight low temperatures I suspect), but today's new arrival was a newly-emerged male Small White. This is the earliest I have seen one Dave Miller
24 Feb Brimstone in Ruislip (TQ097867) Catherine Hookway
24 Feb 1 Small Tortoiseshell basking in sun near The Bourne entrance to Grovelands Park at 13:28 - 13:30 hrs Robert Callf

24 Feb Folly Lane St Albans - My first sightings of Small Tortoiseshells in flight this year. I saw one courting couple, a third nectaring and a fourth sunbathing. At this site, the hibernators usually rely on Dandelions as their main nectar source after emergence. At present there's not a single Dandelion flowering on the whole site and very little alternative nectar sources, which is a source of concern. One male Brimstone also and reports of a female seen on the same site earlier. Worth mentioning also that I saw a Small White flying yesterday on a visit to South London - outside our Branch area, but worth keeping an eye out for an early emergence of white species over the coming week Malcolm Hull
24 Feb Brimstone at St Paul's Walden (TL192222) and at Rookery Wood, King's Walden (TL166232). Small Tortoiseshell at Chalkleys Wood, St Paul's Walden (TL185226) Martin Ketcher
24 Feb Was out in the early afternoon and though I saw half a dozen Brimstones, they had all disappeared by two o'clock. However, this was compensated by the presence of three Commas and three Small Tortoiseshells.
On top of this was the very unusual sighting of a Hummingbird Hawk-Moth. I see few of these here even in the summer, so one in February was a real surprise. I assume it to have been a migrant from southern Europe
Dave Miller
24 Feb Hounslow: Another sunny day with 3 male Brimstones and 2 Small Tortoiseshells spread out across the walk Peter Gore
24 Feb 4 Brimstones in my Great Ashby, Stevenage garden (2 singles and a pair, all males) Steven Lane

20 Feb We returned to the meadows at Ickenham and managed to fill in a few more hedge line gaps across the site. The eggs are without doubt scattered across a large area and in total 16 Brown Hairstreak eggs were found. We found two stems of blackthorn that had two eggs close together but again some eggs were really high up with one being found at least 7 feet up in the blackthorn Liz Goodyear

Date Description Recorder
30 Jan Andrew and I decided to return to Ickenham and visit the fields first to the south of the site. We started just before 9.30 and finished searching at 3.40 - so about 6 hours x 2 = 12 hours!
We first visited the field where Andrew found the 2 Brown Hairstreak eggs last summer and found 2 more but one was 5 feet up on a twig. Another egg later in the day was 6 feet up. We couldn't re-find the summer eggs and it looked like they might have been cut down as there was a lot of brash on the ground where the mower had been in quite close. Having found 2 eggs we didn't search too much of the blackthorn. We walked up the track and then found an egg in the corner but didn't find any more eggs along that particular hedge line. We crossed the fields and walked to the other side where there are some oaks. We found an egg in a small area of scrubbed up grassland close to the railway. We then retraced back to the main fields and followed the hedge line towards our other adult sightings last summer where we found a further 21 (twenty one) eggs. Making a total of 25 in total and 12 Blue-bordered Carpet moths and a cluster of 16-spot ladybirds. One twig had 2 eggs together - a first for us!

22 Jan 1 Red Admiral feeding on Viburnum in the sunshine, this lunchtime in Harlington Andrew Wood
18 Jan In spite of the very cold morning I found one Red Admiral butterfly in my Chorleywood garden. It had its wings closed and was very chilly so I brought it indoors and within 10 minutes it had thawed out and alive enough to set free. It escaped over the rooftops hopefully to live another day Irene Oulsnam
16 Jan Neither Andrew or myself had ever visited Horsenden Hill so despite two egg searches there this year, we couldn't resist visiting. We didn't pick a very nice day and got pretty wet.
We parked opposite the Ballot Box Pub just before 11 and walked the fields close to the road - the blackthorn is seriously impressive and in some places very good but a lot had reddish stems. In our searches today we found 19 Blue-bordered Carpet eggs which always pleases us.
As it got damper and after about 2 ¼ hrs searching (x 2) we started walking towards the infamous Paradise Fields not far from the Canal walk, there was some 'black stemmed' blackthorn. The blackthorn was close to some oak and two slightly greenish Brown Hairstreak eggs were found close together on a single twig. No more eggs were found (nor BBC eggs) but it was getting even wetter and enthusiasm was waning. We did look at Paradise Fields but all the blackthorn was red stemmed. We got back to the car around 2.30
