The beetles discovered in the wooden trunks of artificial Christmas trees last week (see previous ISW post) have been named: the brown fir longhorn beetle (Callidiellum villosulum) and the Japanese cedar longhorn beetle (Callidiellum rufipenne). I'm not sure if they actually found both species or are just unable to confirm ID beyond the genus - read the USDA APHIS note here. Also, the St. Louis Post-Dispatch has published an informative article about the unpublicized recall of trees, including an interview with the woman in Michigan who first discovered the beetles.
