UK's smallest butterfly

[A.P.K.Torry]

I've beaten the small blue (Cupido minimus), as record holder, into 
submission with an astonishing specimen (wild caught) of Silver-Studded Blue 
(Plebejus Argus).
It is a bright blue male with a wingspan of 6mm!

The smallest small blue I have ever seen measured a whopping 8.5mm!

Anyone else noticed that the Silver-Studded Blue is smaller than the small blue.
