Abstract
Larvae of the Scolytidae predator Medetera aldrichii Wheeler pupate in the spring in silk-lined cells constructed in bark galleries of the prey (Bedard 19332). Unlike larvae of the associated predator Enoclerus sphegus (F.) (Coleoptera: Cleridae), or adults of the parasite Cocloides brunneri Viereck (Hymcnoptera: Braconidae), which bore through the bark to emerge (Cowan and Nagel 1965, Ryan and Rudinsky 1962), M. aldrichii lacks structures enabling bark penetration and escapes from prey galleries only through preformed gallery exits (Johnsey 19643).Keywords
