Dark Jerusalem Crickets are a slow-moving, wingless species of cricket common in the southwestern U.S. and Mexico. They are rather large for a cricket and have a bulbous, round head. The most easily identifiable feature of this insect is its humpbacked abdomen featuring black and yellowish striped lines. This type of cricket has large jaws and can deliver a painful bite if mishandled, but it has also been kept as a 'pet'. This critter can be found hiding under logs, rocks and sometimes in homes.
The Jerusalem Cricket has earned itself several playful nicknames including "Potato Bug" (not to be confused with the Potato Beetle which is also called that name), "Earth Baby" and "Nino de la Tierra" (meaning "Child of the Earth").
Mating season occurs in the spring. Females will dig a shallow hole in loose soil and lay her eggs. Nymphs look like small versions of the adult and are equally as slow-moving. Their abdomens are large and heavy, often dragged on the ground, which leaves unique tracks as the Dark Jerusalem Cricket walks. This also produces a scratching noise.
Adults and nymphs eat other insects, potatoes, roots of various plants and decaying plant matter. They are active both day and night, searching for food.
