The oak processionary (OPM) (Thaumetopoea processionea) is a moth whose caterpillars can be found in oak forests, where they feed on oak leaves, causing significant damage. They travel in nose-to-tail processions (hence their name), often arrow-headed, with a leader followed by rows of several caterpillars abreast. [ 1 ]
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 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]

As a consequence, a colony of caterpillars produces large quantities of frass. This is particularly noticeable during outbreaks of the forest tent caterpillar. Frass dropping from treetops in which the caterpillars are feeding create the auditory illusion of rainfall. Tent caterpillars typically have five to six larval instars. It is estimated ...
