Life Cycle
Larvae live in dry tree holes and logs (including southern live oak, Quercus virginiana(1)) and are seldom found. They are also debris-carriers.(5) They overwinter in a cocoon. Female adults continue to feed after ovipositing and thus keep developing eggs.(1)
Adults often come to lights.
