Natural History: Bøving & Champlain (1920) reported that adults are nocturnal predators of Scolytus quadrispinosus Say infesting hickory ( Carya ), who lay eggs in the entrances to S. quadrispinosus galleries. Upon hatching, the larvae prey on large quantities of this scolytine as they move through their galleries where they overwinter as larvae. An adult was also observed preying on an adult Saperda discoidea F. ( Cerambycidae ) as it was ovipositing ( Bøving & Champlain 1920). Knull (1951) reported it as a predator of the native elm bark beetle ( Hylurgopinus rufipes (Eichhoff)) infesting elm. It was frequently found feeding on pink bollworm ( Pectinophora gossypiella Saunders ) larvae in cotton ( Gossypium ) blooms ( Noble, 1969). It has been collected from mesquite ( Prosopis ) and multiple hardwoods and conifers and from the galleries of the buprestid Chrysobothris sp. in mesquite ( Ward et al. 1977). It has also been collected from Acacia ( Rifkind 1997) .
