Leptotes pirithous is a butterfly of the family Lycaenidae on the island of Crete, Greece.
Leptotes pirithous (Linnaeus, 1767)
Lang’s Short-tailed Blue
Family: Lycaenidae > Subfamily: Polyommatinae > Tribus: Polyommatini > Genus: Leptotes
Male to female: 20-25 mm
It has a fast flight, low to the ground.
Leptotes pirithous in Crete live in open land, wetlands, groups of trees with Fabaceae, dry riverbeds with ruderal vegetation, and agricultural land, seaside, and riverbanks.
The larva feeds on Fabaceae (e.g. Medicago sativa, Spartium junceum) plants.
The butterfly flies in at least 2 generations per year.
Lang’s short-tailed Blue could be possibly confused with Long-tailed Blue (Lampides boeticus), but there are significant differences in fingerprint patterns on the underside of the wings. Additionally, Lampides boeticus is larger than Leptodes pirithous.
