Eastern Dappled White

Euchloe ausonia (Hübner, [1804])



A medium sized white butterfly with broken black tips to the forewing upperside, and a marbled green hindwing underside. They have yellow-green eyes, a characteristic of the genius. The white spots in the black tip of the forewing distinguish it from female Anthocharis cardamines. The round white spots on the hindwing underside distinguish it from Pontia edusa, where the white marks are irregularly shaped. Also the black discoidal spot is a thin black bar, and not as large as in P. edusa. The female is similar to the male, but with a slight yellowish cast. It has two overlapping broods a year, flying over hot open ground.

Habitat Requirements

This species occupies very similar habitats to the Orange Tip and perhaps this is for many of the same reasons.

Larval Foodplants

Burnt Candytuft Aethionema saxatile subsp. graecum, Aurinia saxatilis, Buckler Mustard  Biscutella didyma (yellow flowers), Mustard Brassica cretica, Turnip or Field Mustard Brassica rapa (cultivated & naturalised), Southern Warty Cabbage Bunias erucago, White Mustard Sinapis alba (yellow flowers), Charlock Sinapis arvensis.

In Corfu, Anne Sordinas has observed oviposition on Field Mustard Brassica rapa.


A common butterfly in the early spring and on the wing its strong and faster, purposeful flight distinguishes it from the female of A.cardamines.
