Small White

Pieris rapae (Linnaeus, 1758)

Status

Description

A medium white butterfly, with black tips to the forewing upperside, and with pale yellow hindwing underside. The male and female are similar, the male has one black spot and the female two black spots on the forewing upperside. Both have two black spots on the forewing underside. The first brood markings can be faint. The black apical patch on the forewing upperside, which is more along the costa (leading edge) of the wing, than along the margin, enables separation from other members of the genius which it can be easily confused with. 

Habitat Requirements

Ubiquitous - found everywhere.

Larval Foodplants

Arabis Arabis collina (flowers white to purplish-pink), Arabis Arabis turrita (flowers pale yellow), Arabis Arabis verna (flowers white to pale violet), Mustard Brassica cretica, Black Mustard Brassica nigra, Turnip or Field Mustard Brassica rapa (cultivated & naturalised), Swine-cress Lepidium coronopus, Lesser Swinecress Lepidium didymum, Hoary Cress Lepidium draba, White Mustard Sinapis alba (yellow flowers), Hedge Mustard Sisymbrium officinale, Wild Mignonette Reseda lutea, Nasturtium Tropaeolum majus - introduced.

Observations

Whilst this highly migratory species clearly breeds on Corfu, population numbers must be massively inflated by migration events. Its use of Brassicas and Nasturtiums as host plants makes it widely considered a pest.
