Rock-crawlers are important research animals for scientists studying how animals survive in cold temperatures. The distribution of rock-crawlers may also provide clues about where ancient animals lived during the Ice Ages over the past two million years.
ONE OF NATURE'S CHIMERAS
In Greek mythology the Chimera (ki-MER-a) was a fire-breathing monster, part lion, part goat, and part snake. When first discovered high in the mountains of Canada in 1914, rock-crawlers were recognized as the chimeras of the insect world. The first-known species, Grylloblatta campodeiformis, was named after three other kinds of insects: crickets, cockroaches, and diplurans. It was not until 1932 that these puzzling animals were placed in their very own order, the Grylloblattodea.
