Tent caterpillars are on the crawl

RICHMOND — You may have noticed the ugly webbing nestled in the base of branches against the trunks of trees. It is a sure sign the Eastern Tent Caterpillars (ETC) have emerged.

This caterpillar eats the leaves off of trees, especially on wild cherry, apple and crabapple, although it can also be found on hawthorn, maple, cherry, peach, pear and plum as well.

The ETC overwinters as an egg sac on the branches of trees. They begin to hatch at bud break in early March.

The caterpillar is hairy and black with white stripes down their backs and brown and yellow lines along their sides. The adult moth is reddish-brown with two pale stripes running diagonally across each front wing.

The ETC are social insects and congregate together in a silken tent they spin in the crotch of the tree. The caterpillars feed mostly in the morning or at night, defoliating the tree that holds their silk nest.

As the caterpillars grow, so does the nest.

The easiest way to control this insect is to get rid of its nest. If the webbing is low enough, just clean it out by hand. The caterpillars will not hurt you if you do this bare handed, however if you feel squeamish about it, put a plastic bag over your hand and rake out the nest. After removing the webbing, destroy it.

As the nest grows, so does the difficulty of control. If the nest is large, you may need to have to prune it out of the tree. Often people will attempt to burn the nest while it is in the tree. This is not recommended since it will damage the tree.
