Arctic Weevil
A small, dark, flightless weevil with a short broad snout and rough-textured elytra. Adults are nocturnal and hide under stones during the day. Larvae feed on plant roots in tundra soil.
Did You Know?
Being flightless, this weevil relies entirely on walking to disperse, which means isolated Arctic populations can be genetically distinct.
Western Corn Rootworm
One of the most economically damaging corn pests in North America. Larvae feed on corn roots, causing plants to lodge and reducing yields.
Did You Know?
This beetle costs U.S. farmers over one billion dollars annually in crop losses and control expenses.
