Brown Fir Longhorned Beetle

Callidiellum villosulum

Origin: China

Impact: Attacks trees in the Taxodiaceae. North American examples include the sequoia, redwood, and bald cypress. Due to the geographic isolation of some species, especially the sequoias, an infestation of these beetles could be especially dangerous. The Brown Fir longhorned beetle has been found in wood trunks of artificial Christmas trees imported from China. Between 1999 and 2001, more than 20 interceptions of this species were recorded.
