Mark ran his first trap of 2023 on what was another very cool night in Motcombe, 25/05/23. The results were rather disappointing he says but he did have this impressive Poplar Hawkmoth as well as a new species for his garden, a  micro  moth, Tachystola acroxantha.

Matt took these photos at Compton Down on 24/05/2023 and sent them in to us with a degree of uncertainty about the ID of the Brown Argus.  The photo was referred to one of our “verifiers” for confirmation of the ID and he has made the following comments:

This was a super tough challenge as Brown Argus and female Common Blue can be very hard to tell apart – underwing photo is always the best way to tell them apart. Anyway, I’m fairly certain that this is a very worn male Brown Argus mainly based on body shape, the now yellow spots rather than orange more like Brown Argus and very restricted amount of blue. I’d put this out as very probable male Brown Argus and see if anyone else has any other thoughts.

Please send us any thoughts or comments you may have about this ID in the “Leave a Reply” box at the end of this posting.

Yesterday 25/05/2023 my wife and I met up with friends at Badbury Rings to look for butterflies hoping to see Grizzled Skippers. We saw several, and also recorded Dingy Skipper, Brimstone, Small Blue, Common Blue, Speckled Wood and Red Admiral. It was a beautiful sunny day, ideal for a picnic with some butterfly spotting.

First day of seeing the Common Blues at Corfe Mullen Meadows today, 24/05/2023.  I spent a good amount of time watching three dancing away – they also posed beautifully when they landed.

Just sharing this photo of one of eleven Marsh Fritillaries I saw today, 24/05/2023 at Lankham Bottom in a 15-min Count. I actually saw several more after I finished the count! So good numbers considering the season. All seemed fairly fresh. They were all recorded on the north-west facing slope in the gully at the southern end of the site. I didn’t see any on the south-facing slope at the northern end where you also usually see them.

Two photos from Matt sent in telling us:

After reading of the Glanville Fritillary at Compton Down I decided to pay a visit yesterday, 24/05/2023 as did several others.  I wasn’t disappointed, seeing the Glanvilles for the first time, a large number of Adonis Blues and my first Dingy Skipper, Green Hairstreak and Comma of the year.

Kevin sent in this photo telling us:

An excellent Dorset Butterfly Conservation guided walk led by Nigel Spring at Telegraph Hill last Sunday, 21/05/2023 recorded 10 species of butterfly with the highlight being 21 Duke of Burgundy. In addition dragonflies, damselflies, moths, bees, hornets, and a rather confident roebuck were also seen. Towards the end of the walk we were fortunate to observe a female Two-coloured Mason Bee Osmia bicolor carrying dried grass stems to camouflage her snail shell nest.

Paul saw this female Common Blue when he visited Fontmell Down on 23/05/2023 – the females of this species are usually brown with a touch of deep violet-blue near the wing-base which sometimes spreads over most of the upperwing.
