Meadows around Brickendon village. At lunchtime I have walking the meadows around Monks Green Farm, keeping an eye out for any Painted Lady that stopped off for refuelling. Today was the day that I spotted one in the small cover crop which is field mustard I think, very popular with insects. Sunshine is lovely but hoping for some decent rain soon.

10 Green Hairstreak in Hounslow. Todays Branch walk covered Hounslow Heath and Feltham Marshalling Yards. The best Green Hairstreak site in our branch area didn’t disappoint with ten individuals seen. The first, a female was ovipositing on broom. Several more were seen on the ground amongst birds foot-trefoil and broom. But the biggest concentration were nectaring on Green Alkanet, something we have not witnessed before and may be linked to the very dry conditions - some areas of grass were already brown and wild flowers desiccated. Other sightings included Common Blues, Small Coppers, Brown Argus, Mother Shipton, Burnet Companion and Cinnabars. Also of note, two Painted Ladies. Adjoining the car park four large bushes had been stripped of all leaves and were shrouded in larval webs. There were many caterpillars still alive, but with no further leaves left to eat - Spindle Ermine moths. [Posted by Malcolm Hull and Pete Gore]

Sightings from Stanwell Moor. I returned to my local patch today after a couple of days out elsewhere. To be honest, it rarely disappoints and today was no exception. I counted over 100 butterflies, and for the first time this year saw 15 species. Both Holly and Common Blues had their best showing so far, but the highlight was the appearance of another Green Hairstreak, in a spot nowhere near either of the other two I've seen here this year. Today's tally: Holly Blue 19, Common Blue 16, Peacock 15, Brown Argus 11, Small Heath 10, GVW 7, Orange Tip 4, Speckled Wood 4, Red Admiral 3, Small Copper 3, Large White 3, Brimstone 3, Small White 2, Comma 1, Green Hairstreak 1.

Sightings from Stanwell Moor. On a grey day with a chilly northeasterly wind blowing, I didn't really expect to see much in the way of butterflies today. However, some sporadic sunshine appeared late in the afternoon, and a brisk local walk was rewarded by three Speckled Woods (3m), three Brown Argus (1f, 1m), two Common Blues (2m), two Orange Tips (1f, 1m) and a very tatty female Large White.

A short journey along the River Colne and the Whippendell Woods Butterfly walk. I was in need of having my car cleaned so dropped the car off at the Tesco's car park cleaning services which gave me an hour to wander along the River Colne, 2 Green- Veined Whites, 1 Speckled Wood, 1 Brimstone and another unidentified flying White. (Only photo I can post of a butterfly today is a Green-veined White from the River Colne.) As for the Spring branch Butterfly Walk in Whippendell Woods the butterfly count was disappointing, with a count of 1 White and although Rick and myself think it was a GV White it was not confirmed! However it was the best turn out for one of our walks ever! A real mixed age group as well. Rick followed up at the rear to make sure none of the attendees got lost and I was kept busy with questions at the front by the 3 youngest sisters who were amazing for their age at asking such questions about butterflies. Real young stars who made my day for what turned out to be a bad role of the dice with the weather after the recent warm spell. Although it was bad for butterflies this time all who came seemed to enjoy the walk. The bluebells were still in flower we stopped at all the butterfly hotspots to point out what is likely to be seen there and when and hopefully we will get to see more butterflies on the Summer Walk. All attendees seemed to enjoy the walk despite the lack of butterflies and those 3 young girls in the photo were keen to come along on our next walk and it would be a delight to have them there with their family too.
