Grylloblatta campodeiformis(Grylloblattodea: Grylloblattidae) uses saproxylic habitats in subalpine forests of western Alberta, Canada: implications for conservation

Abstract

AbstractGrylloblatta campodeiformis campodeiformisWalker (Grylloblattodea: Grylloblattidae) was commonly collected during summer from trees killed by the mountain pine beetle,Dendroctonus ponderosaeHopkins (Coleoptera: Curculionidae), in subalpine forests of Alberta, Canada. Gut content analysis revealed that the grylloblattids fed on subcortical invertebrates. This newly reported habitat association shows that this species is not limited to strictly alpine habitats and glacial margins, and thus may be more widespread and common than suggested by earlier reports.
