scientific name    Chrysobothris scabripennis    

Conifer forests.


This is another difficult species to distinguish. The beetles look very similar to C. trinervia. Differences in the structure of the male's fore tibia help to identify the species (see key). On the few specimens examined, beetles of scabripennis appear more coppery in colour on the elytra, the callosity on the frons is larger and joins the longitudinal ridge coming down from between the eyes. Beetles of trinervia have a more greenish cast on the elytra, and the callosity on the frons is more disrupted by the coarse punctures and does not touch the longitudinal ridge.

life history


diet info
These beetles are known from a variety of pines and spruce (Fisher 1942, Bright 1987). In Alberta the species is associated with white spruce.

Most specimens have been recorded east of the Rocky Mountains to New Brunswick in Canada, with one record from south-eastern British Columbia. In the United States, these beetles are reported from Oregon and Colorado in the west to West Virginia in the east (Fisher 1942, Bright 1987).
