TILLAMOOK, Ore. (AP) - Tillamook County trees will look less verdant this summer as tent caterpillars, larval moths that live in gauzy tents stretched between tree branches, are eating their leaves.

The Oregonian reports (https://is.gd/kR65H1 ) that state forestry officials said Monday that the native Pacific Northwestern moth has descended on the county, feasting on the leaves of broadleaf trees and shrubs.

Officials say the hungry caterpillars are unlikely to kill most trees, but they strip trees bare of foliage, making them appear dead or diseased. Young or unhealthy trees could be at risk. The caterpillars enter their cocoons in midsummer, allowing most trees to recover.

Insecticides are not necessary to combat the insects. Removing tents from trees by pruning infested branches or blasting them with water is an effective way to minimize outbreaks.
