Life history and bionomics of Glycobius speciosus (Coleoptera: Cerambycidae: Cerambycinae: Clytini).

Glycobius speciosus (Say) was studied in New York State to elucidate poorly known aspects of its biology. Head capsule size from excavated larvae coupled with gallery lengths measured at the time of excavation was used to characterize larval development. Partial life tables indicated nearly 20% of G.
