Life Cycle Edit
A rock crawler's metamorphosis is incomplete, meaning they only have 2 major stages until maturity. Mating can last up to about 4 hours and the female may not lay the eggs for many months. The eggs are laid in rotten wood, moss, rock crevices, and sometimes soil. Nymphal development possibly can take more than five years. Depending on the species, there could be as many as 9 nymphal stages.
Rock crawlers can be found in parts of Asia and North America in deciduos forests, mountains, and caves.
A rock crawler will feed on other insects and will sometimes eat dead or decaying organic matter. Most rock crawlers are nocturnal and daytime hunters.
