(Euproctis chrysorrhoea), a moth of the family Lymantriidae, a dangerous pest of fruit crops and of many forest deciduous species. The moth has a wingspan of 35 mm and is white, sometimes with black spots on the fore wings. The tip of the abdomen has a tuft of golden hairs (hence the name). The moth is found in Europe, Asia Minor, northern Africa, and North America; in the USSR it is distributed in the central zone and, especially, the southern, fruit-growing zone. The young caterpillars hibernate in groups of 200–300 in nests made of leaves woven together with a web and securely fastened in the forks of thin branches. In years of massive reproduction the caterpillars can destroy all the buds and leaves on a tree and cause the loss of an entire harvest. Protective measures include treating trees with insecticides to kill the caterpillars and collecting and burning the winter nests.
