Can someone tell me what this butterfly is? I photographed it in June near Zilnia, Slovakia in Europe. Both photos are of the insect. Thank you.

Dear Jim,
What we could say before doing any research is that your butterfly is a Gossamer Winged Butterfly in the family Lycaenidae and the subfamily Polyommatinae.  Now that we have a brand new computer, our internet research is so much faster.  We quickly tentatively identified your butterfly as a Silver Studded Blue, Plebejus (Plebeius) argus, on the Butterflies of Europe and North Africa website.  The bright blue coloration indicates a male.  Sadly, we cannot link directly to the image on the previous site, but the Butterflies of Norway site has mounted specimens.  They are not as pretty as the living specimens.

    Common Blue (male ) – Polyommatus icarus

    The black borders on a SS Blue are much thicker, and on the underside hindwings, there are round iridescent spots (hence the name ‘Silver-studded’).
