Saproxylic habits.

Larvae and adults prey upon bark beetles, woodboring beetles, and twig nesting wasps in small dead branches of hardwood trees and shrubs (Böving and Champlain 1920; Knull 1932; Foster and Barr 1972); larvae additionally occur within woodier stem galls of cynipid wasps on oak, although food sources in this microhabitat are uncertain (e. g., Eliason and Potter 2000).
