Chalkhill Blues on the wing , so I went to check them out . I found a handful of males , all hunkered down in the grass , only moving when disturbed . One of the largest Blues , almost the 
size of a Gatekeeper , and the last of the Blues to emerge , being found only where their sole food plant , Horseshoe Vetch , grows .Growing too , at the moment , large numbers of Devilsbit Scabious-Succisa pratensis . Hopefully
they will flower this year , after being demolished by the large Rabbit population last year . 
Colour on the slopes came from Wild Basil-Clinopodium vulgare , and the vibrant Yellow-wort-
Blackstonia perfoliata .

Great photos and info as always. If we manage to get to Watlington Hill again this time I hope to see the Chalkhill Blue. I hadn't realised it was that big! It is a large area though and finding the Horseshoe Vetch will be the challenge.
