Ostoma pippingskoeldi, Sierra Nevada, California If you peel back the bark of an old stump in the forests of western North America, there's a good chance you'll find some of these attractive tank-like insects. This is Ostoma pippingskoeldi, a predatory beetle in the family Trogossitidae. They lurk about under bark searching for soft-bodied prey, including the larvae of other beetles. All legs and antennae tucked safely away. Photo details (top): Canon mp-e 65mm 1-5x macro lens on a Canon EOS D60 ISO 100, f13, 1/200 sec, diffused flash (bottom): Nikon coolpix 995, ambient light
