ICE BUG

any insect of the small order Grylloblattodea (about 15 species). This rare and primitive insect is found in the mountains of Japan, western North America, and eastern Siberia. A pale, wingless creature between 15 and 30 mm (0.6 and 1.2 inches) long, it has biting mouthparts, long antennae, and small compound eyes. Grylloblattids usually live beneath rocks near mountain snow lines or beneath rotten logs at lower altitudes. They feed on other insects.
