Submission of records

Please include grid reference (6 digits preferred but 4 digits will do) or post code for your sightings. If you have the what3words app you can supply me with the 3 words denoting the site. Grid reference can be obtained using the Gridreferencefinder or Streetmap. If you need any guidance let me know. Most, if not all, sightings listed here with sufficient detail given, will be added to the branch database but see note below. Some sightings if deemed 'trivial' may not be posted here but will still be included on the database.

Wherever possible please use the iRecord website or app to submit your butterfly (not moth) records to reduce the possibility of transcription errors - please read the General Recording page for details. If you are using a spreadsheet please enter your records in the correct format - see following example; this will ease the amount of work for the county recorder.

For moths however, the much preferred method is to submit your moth records on a spreadsheet, if you can, in the format shown here. More information can be found on the Moths - Introduction page.

NOTE: To avoid any duplication, if you are submitting records via a spreadsheet to the Branch Recorder (Andrew Wood) and also have emailed me for the sightings page please let Andrew or me know. Records entered on the iRecord and iNaturalist databases, for example, will be picked up and verified by Andrew.

Photos are welcome and a selection will be posted on this webpage but please keep these to a reasonably small size. Provide a link if your photo is on an external application like Flickr. Alternatively post your photo on , or

Please email Peter Clarke (peter.clarke4@ntlworld.com) to send in your news.

19 Feb Following on from recent Brown Hairstreak egg finds in the Stanmore area I decided to revisit an area of blackthorn off Old Redding near the Harrow View point first seen in January 2022. It is a public footpath with prunus along the hedge line – in total I found 8 Brown Hairstreak eggs but to my surprise I looked at two probable Cherry Plum bushes that were already flowering and found 2 eggs despite the flowers! Another blackthorn twig had 3 eggs very close to each other

16 Feb One Brown Hairstreak egg found at Moat Mount Open Space, near Barnet
Rohan Harris
15 Feb Having visited Totteridge now four times, the last on Tuesday when it rained - I could only find 4 more Brown Hairstreak eggs but all in slightly different areas, I decided to go somewhere new! I started from Quinta Park in Barnet and followed the Folly Brook Loop walk to Totteridge Fields. Over a 3½ hour period I found 3 Brown Hairstreak eggs which would be a new 2k so although only 3 its 3 more than had been found there!!! I was hopeful that Totteridge Fields LWT Reserve would come up trumps but the blackthorn is not the type of blackthorn I like and a lot had been cut so a wasted walk! However the fields between Totteridge Common and Barnet (Mays Lane) are lined with blackthorn and there must be more eggs to be found? Be warned the mud is dreadful in places!

15 Feb Hounslow. The butterfly year here began early with a male Brimstone on the heath near the railway. It was shortly followed, albeit in the next tetrad along, by what was probably a Comma and then much later a likely Peacock was seen to fly on the far side of Pevensey Road meadows. This could well have emerged from someone's garden shed in the back gardens and it certainly showed more interest in matters the other side of the fences there than in the wide open spaces of the meadows, thus making it impossible for me to confirm that guess either. Nothing else seen so just one definite so far but clearly likely that the hibernating species are around in small numbers for now.
Still working on doing things differently. This was the normal walk of just over 12 miles modified to include extra time on the Marshalling Yard (which is now officially labelled as such and as a nature reserve - good news for sure even if I wasn't rewarded by the butterflies.

15 Feb Tricia Gibbons saw first Brimstone butterfly of 2024 in St Albans garden - so beautiful
(Malcolm Hull)
15 Feb I just had a Brimstone in my St Albans garden. I think that’s the earliest for me
Chris Hocking
12 Feb I returned to Totteridge - it was far too sunny to see eggs properly and terribly muddy! I ended up with a total of 10 Brown Hairstreak eggs, 6 in the same area as Wednesday's eggs finds near Folly Brook but also 3 in different areas of the scrub and a 4th close to where the very first egg in 2020 was found in the main area

11 Feb Red Admiral in my Northaw garden

8 Feb One Brown Hairstreak egg found at Hampstead Heath

7 Feb I have spent the last two days searching the main fields at Totteridge and found 20 Brown Hairstreak eggs in total. Yesterday it was a matter of finding 4 quite quickly and then waiting for at least another 1½ hours before the next eggs were found, today it was a bit easier. However, the more interesting was that today I finished by crossing the Folly Brook where in previous years much searching for eggs has been conducted with no success and 3 Brown Hairstreak eggs were found quite quickly – I will need to return as there is still a lot of blackthorn to check here!
Liz Goodyear
6 Feb Six Brown Hairstreak eggs found at Brockley Hill
Rohan Harris
5 Feb One Brown Hairstreak egg found at Composers Park, Elstree

4 Feb Ian Watts and myself decided to look at Merry Hill in Bushey following on from our close but not close enough Brown Hairstreak egg find last week. There is a lot of blackthorn although some looked unsuitable - some areas ticked all the right boxes, oak, ash, bramble and nectar! In the end we found 14 Brown Hairstreak eggs although nothing for the last hour!!! We think the site, or at least where the eggs were found is about 1½ km inside the Hertfordshire border so we now wonder where else they can be found!

2 Feb So close but so far!! Following on from Rohan Harris’ recent very successful Brown Hairstreak egg finds at Stanmore Country Park, Ian Watts and myself decided to try and find an egg in Hertfordshire today so we followed the London Loop from Aldenham Country Park towards Stanmore Common. Needless to say the first decent blackthorn we found was where a ditch forms the boundary between Greater London and Hertfordshire. We found two Brown Hairstreak eggs one was 25 yards from the county border and the second was even closer at 10 yards! After that on our very muddy route back via Elstree, there was more blackthorn along the London Loop (which we didn't search) but after we turned off back towards Elstree we found very little!

(Peter Clarke)
25 Jan Took a walk around my local fields in Ware this morning and finally found a White-letter Hairstreak egg on the elms by the playing field (usually much easier to find). Of note was that some of the elm flower buds were starting to burst. On blackthorn 5 Blue-bordered Carpet along Wood Lane and a further egg along the hedge near Hollycross Road. Had an odd egg which was on an oak leaf bud, where a Purple Hairstreak egg would be found – but it was ridged. Looked like a Green-brindled Crescent but wrong larval food plant and laying location???

14 Jan Branch Event
Brown Hairstreak egg search at Stafford Road Open Space, Ruislip

Volunteers joined a small handful of regulars at the Stafford Road Open Space in Ruislip to help with the annual egg survey for the Brown Hairstreak. Postponed from the original date because of potential snow, the new date proved to be a very fine day to be out searching. Most of the volunteers were new to the task but it took barely a minute to find the first egg and show exactly what it was that we were looking for. In fact, the first Blackthorn bush that was searched contained 10 eggs and, spreading out, the volunteers soon got into their stride with egg finds coming thick and fast. In the public Open Space area, it seemed that almost all of the Blackthorn contained at least an egg or two and every attendee had success finding eggs.
In only a couple of hours or so of searching, a total of 103 Brown Hairstreak eggs (plus one Purple Hairstreak egg) were found, an excellent result that is consistent with the record number of adult sightings last summer. The Ruislip site seems to be going from strength to strength.
Alongside the volunteer egg search, Malcolm Hull, Liz Goodyear and Nick Furtek met with Ricky, an enthusiastic representative of TfL, to search for eggs on the adjacent TfL owned land that is not accessible to the general public. A total of 15 Brown Hairstreak eggs were found, reinforcing how much this beautiful butterfly species is now part of the wider Ickenham and Ruislip landscape.
