Went to Martin Down yesterday and as I saw clouds of Chalkhill Blues there thought I would try Badbury early this morning, 12/07/2025 and eventually found a solitary one on its overnight roost.

Two photos sent in by Mark telling us:
Spent a few hours at Badbury Rings this morning, 04/08/2024 and despite the overcast conditions Chalk Hill Blues were in abundance, but not a great deal else except for a handful of fresh Common Blues which were very welcome.
Editor’s Note: It took a considerable amount of research by Mark to enable him to identify this aberrant female Chalkhill Blue for which we thank him.

Penny tells us
Perryfields on Portland was teeming with Blues today (12 August) – lots of Common Blues, and lots of Chalkhills. I love Chalkhills, and love a Carline Thistle, so I’m pleased to combine the two! (Also lots of Blues and Chalkhills at High Angle Battery today.)

Scott sent in these two photos telling us:
I visited the Isle of Portland on 17/07/2024 where I did the big butterfly count. After finishing I saw my target species, a single Chalkhill Blue – these photos of the upper and underside are both are of the same individual taken at around midday near to the Olympic rings.
