BEHAVIORS
This species lives statewide in woodlands with native grasses. In the southern one-half of the state, the larvae eat inland oats (Chasmanthium latifolium). In the northern one-half of the state, the larvae eat other species of native grasses. The adults feed on tree sap, dead animals, rotten fruit and the solid wastes of animals. Two generations are produced per year. The larval stage overwinters.
