Following Mark Pike’s comment that Compton Down was awash with butterflies, I went up there yesterday morning (24.05). I got there early, so watched the Down come alive as it warmed up.

The Adonis Blues were too numerous to count, there must have been well over 100!

I saw at least 8 mating pairs, and saw males flying while mating, so the females (with wings closed) were towed around backwards behind them!

The Small Blues are just out. Mark spotted this one at Compton Down (North Dorset) on 07/05/2019. They have also been seen at Fontmell Down, not far from Compton Down, and 16 were counted on the Weymouth Relief Road cutting.

They are tiny butterflies, appearing a silver-grey colour in flight. They are quite rare, but became more widespread in Dorset between 2010 and 2014. Nationally, they have reduced in abundance.

Dave says: “Considering Holly Blues were quite scarce last summer its great to see them almost everywhere around North Dorset . This pair were seen at Compton Down [on 19/04/2017] along with several Green Hairstreak and plenty of Speckled Wood. However across the valley on Fontmell Down it appears worryingly lifeless within the boundaries of the fencing. Only a few Grizzled Skippers seen and hardly any nectar sources plus cattle grazing still going on ! Outside the boundaries plenty of cowslip, daisy and hawkweeds . Hope it rapidly improves “.
