Appearance: Small (1.2-1.8 cm wingspan), white/grey wings with scattered dark scales, often with indistinct lines and a dotted border on the wing edge.
Habitat: Common near coasts in maquis shrubland, cultivated fields, and walls in SW Europe & NW Africa.
Larval Diet: Feeds on herbs near the ground, including Oxalis in the Azores.
