Coleoptera of Great Smoky Mountains National Park Species Pages

Family Cerambycidae

            Subfamily Lepturinae

 Anthophylax attenuatus Haldeman

Description and Taxonomy

Length 12-17 mm. Of four species in the genus, this is the only one that is not metallic. The dense tufts of white hairs on the reddish-brown elytra make it easy to recognize. Females are more robust than males. The generic key and description in Linsley and Chemsak (1972) and characters described and illustrated by Yanega (1996) are the best published references for identification. 

Life History

Little seems to be published on the biology of this species and its congeners. According to Linsley and Chemsak (1972) larvae occur in "very moist, decaying hardwood logs, making large irregular galleries loosely packed with fibrous frass." They pupate in soil. Recorded hosts include maple, beech, poplars, and wood of other hardwood trees. Those authors also report a flower record from "male flowers of pine." Specimens from GSMNP were collected at various elevations in malaise traps and Lindgren funnels.


This is predominantly a northern species recorded from Virginia to Maine, and west to Minnesota. Specimens from GSMNP were all collected in the eastern half of the park, and these records may represent the southern limit of the species.

Conservation Concerns

The species is not known to be under threat.
