emerald ash borers at wasp nest
The predatory wasp Cerceris fumipennis, which some call the smoky-winged beetle bandit, collects adults in the Buprestidae family (metallic wood-boring or jewel beetles) to feed to its young. Among such beetles is the emerald ash borer (Agrilus planipennis), two of which are shown here abandoned near a wasp’s nest entrance. (Photo by Claire Rutledge, Ph.D.)
