Thymelicus acteon could have been mixed in, but I don't think so.

Papilio alexanor
Leptidea sinapis
Aporia crataegi
Pieris krueperi - I did try, but without results
Euchloe ausonia
Anthocharis cardamines
Gonepteryx farinosa - the few that stopped were not these
Satyrium spini
Satyrium acaciae
Callophrys rubi
Lycaena alciphron
Leptotes pirithous
Pseudophilotes vicrama - plenty of unconfirmed small blues, but the ones I did ID were small P. icaruses.
Glaucopsyche alexis
Danaus chrysippus
Pararge aegeria - quite surprising to miss this
Hyponephele lupinus - possibly seen, but no way to make sure
Maniola megala - possibly in aestivation

Melitaea telona
If someone else is going there I can heartily recommend the walk from Argennos to Vigla. For the circular route (done CW) the first part of descent can be difficult with no or almost no path and steep descent, but there is no reason to make it circular. The best parts were on ascent and that was on tracks.
Starting from the village you descent to the main road ... and the fun begins immediately with quite lush vegetation at the roadside. Then follows a drier section of track and a bit of field and then you are inside the woods. When you continue up, you encounter clearings and streams and the forest gradually changes to drier and the trees to pine, but there are plenty of butterflies everywhere. Finally the trees disappear and the top is open ground with rocks and some green in-between.
The rest of the trip was drier and much less interesting, so a return trip can be even better than circular.
