Brown fir longhorned beetle
Brown fir longhorned beetle (Callidiellum villosulum) is an insect pest of certain cedar and fir species. It is a native of China and was first detected in Pennsylvania in 2016.
It has been intercepted in several states in the Midwestern U.S. on artificial Christmas tree imported from China containing centerposts or bases made from Chinese fir, Cunninghamia lanceolata. Its known host range is narrow and it is not clear if it can adapt to North American host trees.
