The oak processionary moth, Thaumetopoea processionea, is established in Europe and feeds primarily on deciduous oak (Quercus) species. The insect has one generation per year and overwinters as eggs laid on branches of oak trees. After emergence, the larvae feed gregariously and from the 5 instar form a communal silken nest on the tree from which they typically migrate in procession to feed. Feeding may result in partial or complete tree defoliation. From the third instar, the larvae produce urticating hairs which may cause allergic reactions in humans and animals.
