Range: Eastern North America: Quebec south to Florida, west to Texas, Minnesota
Habitat: Deciduous forests
Season: May-October (Northeast). June-August (North Carolina). July-August (Kansas)
Life Cycle: Two-year life cycle. Eggs are laid beneath the scales of the bark on living oak (or sometimes maple) trees. Larvae feed beneath the bark for the first year, then migrate to heartwood for second year. They overwinter as larvae and pupate in spring, emerge in spring and summer. * Can be abundant enough to cause substantial damage at times.
