Polyommatine Blue

thank you dotun55

Very nice

Thanks for the ventral shot Stanislav! This was necessary to get the genus. I agree with bayucca's final diagnosis.

thanks for all the help, bayucca!

It is either Plebejus idas, Plebejus argus or Plebejus argyrognomon. You only can separate Argus from the two others by a closer look of the tibia. And all three only by genital dissection. I it is a Plebejus sp.
@Caleb: You were not so far away, but not close enough to be 100% sure ;-)...
These European Blues are really very tricky to ID!

i added photo to gallery

Yes, underside, sorry...

ohhh ...ventral view , wrong translation for me ...

No sorry about your english, for me it's fine!
But from the butterfly itself, you do not have any other picture??

photo is take much later than photo with butterfly , but at the same spot where butterfly :)
Butterfly was spotted in that area (sorry about english )

Where is the butterfly?? ;-)...

i am not sure if you want view like this ?

Is there any chance to get a ventral view??

Hmm, you have the wrong altitude! At least for my candidate ;-)...
There are Eros from lower altitude (350 m), but that subspecies is probably found more in the Balkan area, not so far in the north...
OK, let's continue...

345m above sea level

There is a Polyommatinae eros boisduvalii from exactly your area. Habitat: dry grassy places, woodland clearings and glades. Univoltine from mid June to mid August. Would the habitat fit?

Altitude?

bayucca , definitely not in a city , i know the exact location , edditing right now

That was after all my comment some time ago ;-)...
I would also not bet my ranch on any of the candidates...

Thanks bayucca. Caleb, I am personally unable to identify this butterfly at Genus level, with the criteria that I am familiar with. For this reason, I am not making a formal suggestion. The ID so far with Polyommatinae is at least correct.

Could be Plebeius argus, but the dark spots seems to be much smaller in Stan's. My closest guess would Polyommatus eros, without being that sure and I do not have the time for a discussion, sorry. And I am not that sure, that I dare to make a suggestion.

My main concern about Eros is the habitat and range. It might be more in the mountane areas.
Please, Stan, can you check your location again. Is it really found in the middle of a city? What altitude you were?

danielle, i am fairly certain it is a silver-studded blue. If you think otherwise, you could make a suggestion and we can discuss it.

Caleb, are there any specific reasons you are now making this suggestion? Making formal suggestions is more than just guessing. In the sub-family Polyommatinae and the genus Plebejus, there are many European butterflies that look similar from the top; they are typically identified looking at ventral patterns, which are not available on this spotting. Often you also need to examine their genitalia to be sure.

Caleb, as indicated by its name and clearly shown in the pictures and descriptions in your link, the Short-tailed Blue has two short tails. This butterfly has no tails.

check this link. It could be a few of these, although my best guess is a short-tailed blue
