The Jerusalem cricket (Stenopelmatus spp.) — also called a potato bug, skull insect, or child of the earth — is not a true cricket but is commonly grouped with them due to superficial similarities. It is one of Arizona's most distinctive and frequently misidentified insects. Adults have a large, round, bald head with prominent mandibles, a striped abdomen, and powerful legs built for digging. They are entirely subterranean, spending most of their lives underground where they feed on decaying plant matter, tubers, and other insects. Jerusalem crickets are nocturnal and are most often encountered when they surface after rain or during landscaping work. Despite their fearsome appearance, they are not venomous and rarely bite unless handled roughly — though their mandibles are strong enough to break skin.
