The Silver-studded Blue Butterfly.
The heathlands of Southern England is the likely place you will find the Silver-studded.
The Isle of Portland is a stronghold of this species and where I shot these images in a disused Quarry.
The average wing span of this very small species is (29mm) for the male and (31mm) for the female.
The flight time is usually July to August. These are quite early this year.
The image below shows the scale of the Silver-studded against grass.
The Silver-studded lives in small colonies and never travels farther than about 50 yards in its lifetime.

Below is Yellow Wort flower which I observed at the same location as the Butterfly.
The flower below is the Common Centaury, also observed at the location.
To identify the Silver-studded look out for the little silver marks within the larger black round marks on the underside of the wing.
