Best time to see: mid Apr to early Jul
Key facts
Unmistakable white butterfly with bright orange wingtips (although no orange on females)
Habitat: where the caterpillar's food plant is abundant crucifers such as lady's smock or garlic mustard
Common throughout England, Wales and Ireland
Recognition
Male's orange wing tips are distinctive; both sexes have a mottled pattern under the hindwing, looking rather like lichen
A mobile butterfly, males often seen flitting slowly between white objects looking for females
Female can be confused with Small or Green-veined White, but neither has a central black spot on the forewing nor the mottled u/s
Lifecycle
White eggs, turning bright orange, laid singly on tall crucifers in late May and June
Dark green caterpillars lie along the seedpods of food plants in June and July, leaving these to pupate in dense vegetation
Adults emerge from April onwards to begin the search for partners
