Plebeius blue

Thank you bayucca

Tricky one. In my eyes it is a Plebeius sp. Unfortunately there is a full complex of Plebeius which cannot safely distinguished from only the ventral view and without genital dissection. Candidates are P. argus, P. idas and Plebeius argyrognomon. P. argus in addition has a very tiny thorn at the anterior tibia, which is missing in the other two species. If you have a dorsal view we might get a little bit closer, however, most of the time this not really helps much. Many IDs you will find are anyway questionable based on my previously mentioned criteria.
