Euchloe ausonia is a butterfly of the family Pieridae on the island of Crete, Greece.
Euchloe ausonia (Hübner, 1804)
Eastern Dappled White
Family: Pieridae > Subfamily: Pierinae > Tribus: Anthocharini > Genus: Euchloe
Male to female: 45-55 mm
The forewings are white with black tips and a black spot at the end of cell. The underside of the hindwing is characterized by black and yellow scales, which create a greenish-white variable pattern. The female is generally darker.
It is often seen at roadsides and in areas of cultivation in the early spring. It has a fast and strong flight.
Euchloe ausonia in Crete lives in dry-warm, usually semi-open habitats such as bushy rocky slopes, clear olive groves, forest edges, or dry ruderal terrain.
The larva feeds on Brassicaceae (Cruciferae) plants.
The butterfly flies in 2 generations per year.
The butterfly could be confused with another Pieridae present on the island, Pontia edusa. Here are some useful tips to spot the difference:
- On the underside of the hindwing, the white marks of Euchloe Ausonia appear to be round white and can be distinguished from Pontia edusa, where these marks are irregularly shaped.
- The black discoidal spot is a thin black bar, and not as large as in Pontia edusa.
- There is a white mark near the apex on the upper side of the forewing that is absent in Pontia edusa.
