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 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 pupate within the feeding tunnels, but adult caterpillars have also been found on dried leaves, which indicates that they also leave the feeding ...
The oak beauty caterpillar is brown, marbled with white, and has two small red lumps on the back of its eighth, ninth and twelfth segments and a small lump on the belly on the seventh, eighth and ninth segments. The caterpillar's head is slightly notched in the middle, possibly due to evolutionary pressures to resemble twigs in appearance.
The Entomology and Nematology department of the University of Florida writes that the caterpillar is found "from New Jersey to Florida and west to Arkansas and Texas (Covell 2005). It is common in ...
The caterpillars may be found feeding on an extremely wide variety of trees, both deciduous and coniferous, including apple, birch, black locust, cherry, elm, fir, hackberry, hemlock, hickory, larch, oak, rose, spruce, chestnut, and willow. [2] Defoliating outbreaks are occasionally reported especially on Manitoba maple and elm in urban areas. [4]
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 ...
The caterpillars are gray or greenish with dull brownish yellow or rosy stripes. There are scales on each segment and two long spines on the mesothorax. [3] The caterpillars pupate for a short time. [4] They feed on the foliage of oak trees, maples, birches, and hazels. The caterpillar overwinters in the soil as a pupa.
