Grylloblatta campodeiformis

Rock crawlers are insects that somewhat resemble large ants with an earwigs body. Rock crawlers do, indeed, crawl around rocks. They belong to one order: Grylloblattodea, and one family: Grylloblattidae. Only 25 species of rock crawler have been identified. Rock crawlers are small and wingless that weren't discovered in the Canadian Rockies until 1906.

Appearance Edit

These insects come in colors of pale brown, yellow-brown or grey. The body is covered with short hairs. They have relatively slender cerci with a small head and long, pale antennae. Their eyes are small, but depending on the species, eyes could be absent. Most of these insects are between 1/2- 1 1/4 inches (1.2- 3 centimeters).

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.

Occurence Edit

Rock crawlers can be found in parts of Asia and North America in deciduos forests, mountains, and caves.

Feeding Edit

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.
