The Green Hairstreak Butterfly (Callophrys rubi)
Yesterday - was the earliest date that I have found the Green Hairstreak in the season.
With a wingspan of 33mm (15mm closed), green in colour on the underside (wings always closed when at rest) and favouring the green leaves and white flowers of the Hawthorn bush, its not the easiest species to find. Fortunately I always check a certain location where it is known that in the past they colonise provides some advantage. This species is the most widely distributed Hairstreak in the UK, that said it is not found everywhere, mostly in Southern England and Wales.
If you can find one pitched then they can been observed, but if disturbed they are so difficult to follow and involves some luck in keeping up with.
Interestingly it is a very dull brown on the upper wings, but you never see it and you would be very fortunate to get a good shot of it. My latest blurred effort is at the foot of this post.
