A common species throughout Belgium.
Eggs are pale yellowish when freshly laid, turning pale greenish later. The eggs are laid singly on the underside of the leaves of the larval foodplant.
The larva resembles Pieris rapae but lacks the yellow dorsal line. The lateral stigmata have yellow spots like in P. rapae but these lack in the second and third thoracal segment.
An overview of the bionomics of this species can be found on the the Butterflies in the Benelux website
The adults fly in at least three generations per year, almost continuously from mid April till September.
The larva lives on Cardamine, Nasturtium, Lepidium, Lunaria, Hesperia, Arabis etc.
There is overlap in use of foodplants with Anthocharis cardamines but larvae of that species are specialised in eating the seedbuts of the plants and this species eats the leaves so there is no niche overlap.
Widespread and common throughout, often in more natural and more damp habitats than Pieris rapae.
