Description

Papilio alexanor is similar to Papilio machaon, however, the basal third of the forewing is not entirely black, but bordered basally and distally by a broad black band. The bands are continued across the hindwing, bordering also here the yellow basal area.

The larva is similar to that of P. machaon but more variegated, the red dots larger and brighter; it is easy to find, since the stalks of the plants on which it feeds become white, the epidermis being gnawed. Pupa are stone grey, very flat, with carinate sides and uneven surface; fastened on stones and resembling a small stone splinter.
