The caterpillar is a serious pest that attacks more than 30 crops. The larva bores into the trunk or branches about 15–25 cm deep. The tunnel created is empty in the day time, but is filled with caterpillar during the night. It damages the bark of the tree resulting in dieback of the stem. Frass is visible in affected areas. [4]
The caterpillars live from August to May in feeding tunnels and round chambers under the bark of tree trunks. The infestation can be recognized by the light brown caterpillar droppings, which appear in bark cracks. Preference is given to old trees and those weakened by annual tree pruning.
The caterpillars are mostly found in oak trees or on the ground under them in late spring and early summer, and do not live on fences, walls, etc. as other caterpillars do. They have very long, white hairs contrasting markedly with shorter hairs. [1] The caterpillars of several other species may be mistaken for the oak processionary. [3]
The caterpillar's head is slightly notched in the middle, possibly due to evolutionary pressures to resemble twigs in appearance. [6] The larvae are found from spring to fall feed on a variety of deciduous trees including oak (Quercus spp.), elm (Ulmus spp.), hazel (Corylus avellana), aspen (Populus tremula) and alder (Alnus glutinosa).

Adult Archips semiferanus moths lay masses of 40 to 50 eggs on oak tree branches and rough bark in July; these overwinter and hatch the next spring. The larvae eat tree buds and young leaves, then roll leaves together with silk (hence the name). They nest and eat inside the rolled leaves, then pupate in the leaves or crevices in June. After a ...
