Oak Leaf Caterpillars

Mealy Bug

Oak leaf caterpillars start off as non-feeding larvae that are cocooned on the ground. It emerges as a moth the following spring. Female moth lays 500 eggs on leaves of the trees. Hatched larvae feed on leaves, then drop to the ground and pupate. Emerging as adults they start this viscous cycle all over again. These caterpillars defoliate the trees. Full grown larvae are 1 to 1 ½ inches long. They are greenish yellow in color and have a narrow white stripe down the center of the back. Their heads are brown and curved with white and black bands.
