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.

Sightings from Stanwell Moor. A early start for a local walk today ahead of the forecast hot afternoon. 14 species seen today, including another new one for the year (making 17 for my local patch so far in 2025). No.17 was the Green Hairstreak. One popped up out of nowhere in a new location, but the second (the pic attached) turned up precisely where I saw one last year. The behaviour was the same as well - chasing Holly Blues. Overall, numbers were subdued in the heat, with only Orange Tips and Holly Blues making it to double figures. One other highlight of the morning was a very new female Brown Argus nectaring on the caterpillar foodplant. [Posted by Dave Miller]
