Pontia edusa is a small to medium-sized migrant butterfly, with a wingspan reaching about 45 mm. The upperside of the wings is white, with black stains on the top of the forewing and hindwing. The hindwing undersides have greenish-grey spots. The butterfly is nearly identical to Pontia daplidice. Investigations of the genitals are the only way to distinguish between these two types.Script error: No such module "Unsubst".
The adults fly from March to October[1][2] with two to four generations depending on the latitude. The eggs are laid singly and have an incubation period of seven days. The caterpillars are present from May. They are greyish-greenish, with black dots and broad yellow stripes, quite similar to the larva of the cabbage butterfly (Pieris brassicae). The larvae feed on Resedaceae species. Pontia edusa hibernates in the chrysalis stage.
