Black-Veined White Butterfly

 

(Aporia crataegi), a butterfly of the family Pieridae. The wingspan is up to 65 mm, and the wings are white with black veins. The caterpillar is up to 45 mm long, grayish-brown with stripes on the back. The butterfly inhabits temperate and sometimes northern parts of Eurasia and North America. It is harmful to fruit trees. The butterflies fly out in June, laying eggs in small heaps of 30–150 on leaves. The caterpillars appear at the end of summer and skeletonize the leaves. They winter in nests in trees; in spring they crawl out of the nests and eat away buds, leaves, flower buds, and flowers. Control measures include collecting and burning the winter nests and spraying crops with insecticides.
