Sightings from Stanwell Moor. Increasingly warm sunshine today, and I counted 13 species on my local patch again. However, Brown Argus didn't appear this time, but the gap was filled by my first Common Blues of 2025. The other 12 species were the same selection, and included these two mating pairs - GVW and Large White. [Posted by Dave Miller]

Green Hairstreak on Hounslow Heath & Marshalling Yards. News from Pete Gore "On yesterday's walk in the sun I saw 5 Green Hairstreaks on the part of the marshalling yards where we saw them last year, the first I've seen there despite frequent walks in ideal conditions earlier. One more was seen above the culvert and one in the strongest area of the heath where I didn't get as lucky with the sun particularly on the afternoon return journey. This grand total of 7 would in some past years have been a whole season's worth so I'm assuming that we have a thriving butterfly species with probably emerging and active females, and that it should be well worth a visit to both sites on May 11th - weather currently looking good." Join Pete and I on Sunday May 11th to see Green Hairstreaks at their best site in the Branch area - details on Events page [Posted by Peter Gore & Malcolm Hull]

Bentley Priory nature reserve. A warm but mostly overcast afternoon kept the butterfly sightings down. With 3 Peacock, 2 Orange-tip, 1 Green-veined White and 6+ unidentified flying whites. [Posted by Peter Fewell]


Sightings from Staines Moor. I popped down to Staines Moor this afternoon to see if any Small Coppers had emerged there, following my sightings of the species earlier in the day near Stanwell Moor a couple of km to the north. I drew a blank with this, but I did find a nest of around 100 Small Tortoiseshell caterpillars - a heartening sight considering the scarcity of the species these days. There was also a single Red Admiral caterpillar tucked into a nettle leaf in amongst the Tortoiseshells. On the adult butterfly front, there were a few Peacocks, GVW and Orange Tips, plus a Red Admiral. [Posted by Dave Miller]

Waterford Heath. A lunchtime walk around Waterford Heath with the family, was warm but not hot with gentle sun and partial cloud. Dotted around I saw 5 Grizzled Skippers in the North Heath and 4 in the South including a mating pair, 1 pristine Brown Argus (first seen by the missus, sadly flew away as I was getting my phone out to photograph) seen on the path between the central bench and gate to the silt pit in the South Heath. Also seen Cinnabar moth and one UFM, possibly a Mother Shipton which also gave me the slip. Regrettably the amount of dog poo around is an absolute disgrace, some people have no shame or respect.

Starting from Rickmansworth Road and taking the right hand path down where I saw: Holly blue x 4, Peacock x 3, Speckled wood x 2 and 5 x unknown whites. I then went into the Nature Reserve where I saw, Orange tip x 5+, and 6 unknown whites, Red admiral x 1, and Brimstone x 3. crossing the river I went along the other side (where the Small tortoiseshells used to be), Peacock x 2, Brimstone x 1, Orange tip x 1, and another two unknown whites. Heading back up the other side of the Park, a Peacock and Green-veined white on the way, to the Green Gym/Peace Garden where I saw another Peacock, Speckled wood and another two whites (wish they'd stay still for an ID). One Comma by the Croquet Club, and then home to a Holly blue in the garden. [Posted by Rick Vickers]
