Saperda inornata
Poplar-gall Saperda
Saperda inornata is a longhorned beetle (Cerambycidae) native to North America, closely associated with trembling aspen (Populus tremuloides) throughout its life cycle. Larvae develop within living aspen trees, tunneling through wood and inner bark, while adults feed on bark and other tree tissues. The species was described by Thomas Say in 1824 and occurs across Canada and the United States. It has been observed in Manitoba, New Brunswick, Nova Scotia, and Ontario in Canada, as well as the northern United States.
