I've found this species
in Greece and in Slovakia and now Romania. It is local but common in these countries. It
seems to like clearings and roadside verges in forests at moderate
altitudes. It flies in several broods during the spring summer and
It is one of Europe's three Short Tailed Blues. It
has the most restricted range being confined to the east of the region.
The three species are distinguished as follows:
Short Tailed Blue, E. argiades -
the only one with distinct orange marks on the underside hindwing.
Larger than the other two species. Most widespread. Central Europe and N
Spain. Violet blue upperside in the male.
Provençal Short Tailed Blue, E.
alcetas - smaller, no orange markings, patchy distribution from N
Spain and across southern Europe, upperside forewing without black cell
spot. Truer blue upperside in the male.
Eastern Short Tailed Blue, E.
decoloratus - as E. alcetas but eastern distribution and

distinct upperside forewing black cell spot in the male. Violet blue
upperside in the male. Tail is very short, apparently not present in
