Found near river banks and adjacent higher ground, this beetle's larvae attack poplar trees (Populus). Eggs are laid on the bark in fall and the larvae tunnel into the wood. They overwinter and proceed to eat the tree for two or three years, working their way deeper inside. They pupate in chambers just below the bark and then emerge July-September.
