Aporia crataegi
"It is the only large white butterfly with all the veins lined black and lacks any other marks. Only the Clouded Apollo, Parnassius mnemosyne, is similar but this has two large black spots on the forewing. See illustration above."
"Meadows with scrub or cultivated areas with fruit trees. Larvae feed on various fruit tree species (Prunus) and Blackthorn plus Hawthorns (Crataegus) and a few other bushes."
