This species is very similar to the Bath White, but is considered to be biologically distinct. Biochemical differences between the two species are thought to be sufficient to prevent interbreeding.
It is found in NW France, eastern France, central and south-east Europe, Iraq, Iran and central and east Asia.
Favoured habitata are hot, dry, often barren stony places. It is common on disturbed ground where the LHP grows.
This species is polyvoltine, with adults being on the wing between March and October according to locality.
Larvae feed on plants in the Resedaceae family, principally White Mignonette (Reseda alba). It will also use crucifers.
A very fast flier with nomadic tendencies.
