Celastrina argiolus is a butterfly of the family Lycaenidae on the island of Crete, Greece.
Celastrina argiolus (Linnaeus, 1758)
Family: Lycaenidae > Subfamily: Polyommatinae > Tribus: Polyommatini > Genus: Celastrina
Male to female: 30-35 mm
It is a small blue butterfly when seen with open wings and pale grey-blue, or silver-blue with small black spots underwing.
The female differs from the male; it has both wings broadly black-bordered, and the margin of the hindwing is bearing vestiges of ocelli.
The butterfly flies very fast and rarely opens the wings when still. It is usually observed to fly high rather than low to the ground.
Celastrina argiolus in Crete can be found in olive groves, vineyards, small clearings, mixed forests, and scrub.
The larva feeds on Ericaceae, Rhamnaceae, and Rosaceae (Rubus sanctus).
The butterfly flies in at least 2 generations per year.
The butterfly has a unique appearance in Crete and can’t be confused with other Lycaenidae species of the island.
