Oberea schaumii
Oberea schaumii is a cerambycid beetle that develops as larvae in trembling aspen (Populus tremuloides). The species has a variable life cycle duration: most individuals require three years to develop, though some complete development in two years and others require four. Adults emerge from late June through July. The beetle occurs in the crowns of large aspen trees and shows competitive interactions with Saperda inornata.
