The over-winteringlarvse burrow into the tender shoots in early spring, causethem to die and give the tree the appearance of havingbeen scorched by fire; the summer generations likewise burrowin the new growth but also attack the fruit, particularly oflate varieties. The insect hibernates as a small larva, about -^ inch inlength, in a silk-lined cavity just beneath the outer bark, usuallyin the crotch at the base of the new growth. The location ofthe hibernating cavities is indicated by the small, reddish-brownmounds of bits of bark webbed together with silk
