Lampides boeticus


Lampides boeticus is a butterfly of the family Lycaenidae on the island of Crete, Greece.

Scientific name

Lampides boeticus (Linnaeus, 1767)

Common name

Long-tailed Blue, Pea Blue


Family: Lycaenidae > Subfamily: Polyommatinae > Tribus: Polyommatini > Genus: Lampides


Male to female: 30-35 mm

On the upper side of the wings, the males have a blue-purple color with a very thin dark brown band in the submarginal area, while the females appear to be light brown colored with blue shades in basal and discal areas.
The underside of the wings is light brown and adorned with several small white bands and a larger white submarginal streak. Beside each tail, on each hindwing, there is a pair of small half-black half-green blue eye-spots and small orange marginal spots at the anal angle.
Both sexes have the same appearance on the underside of the wings.

The antennae-like “tails" on the hindwings, along with the colorful eye-spots at the anal angle, create the impression of a false head and divert the attention of birds away from the body. It has a quick flight.


Lampides boeticus in Crete is present in various habitats such as gardens with legumes, meadows, ruderal areas or hot scrub, riverbanks, and mountain fields.

Food plant

The larva feeds on Fabaceae (Medicago sativa, Spartium junceum) plants.

Flight Period

The butterfly flies in at least 2 generations per year.

Long-tailed Blue could be possibly confused with Lang’s short-tailed blue (Leptotes pirithous), but there are significant differences in fingerprint patterns on the underside of the wings. Additionally, Lampides boeticus is larger than Leptotes pirithous.
