Female has 16-18 serrated segments. Other eastern Prionus have 12-13 antennal segments (1).

Range

Central and eastern United States, southern Canada.

Habitat

Deciduous forests and adjacent areas

Season

April to November (Northeast). May-July (North Carolina)

Life Cycle

Female lays 100-200 eggs around the base of various trees, vines, herbs. (These include oak, grape, pear, and maize.) Larvae feed on bark and roots. Larval stage lasts three years or more. Strongly attracted to lights.

Remarks

On mid-summer nights, these hit lighted windows so hard at my house in Durham, North Carolina, that I fear the glass will break. Seems that mostly males come to lights.
