Golden Stonefly
A large predatory stonefly with a golden-brown body found in western North American rivers. Its nymphs are active hunters on the streambed.
Did You Know?
Golden stonefly nymphs are apex predators of the streambed, hunting mayfly and caddisfly larvae among the cobbles.
Round-bodied Scydmaenine
A minute, convex rove beetle of the subfamily Scydmaeninae with a distinctively constricted waist between thorax and abdomen. It is a specialized predator of armored mites in forest soil.
