    Jerusalem Cricket - (Stenopelmatus fuscus)

    The Jerusalem cricket is a North American camel cricket that leaves an impression on observers as well as a depression in the soil.

    Staff Writer (10/9/2017): This slow-moving, humpbacked insect is often taken for a spider until one counts the number of legs. They are very slow in spring during their mating season.

    They are members of the Camel Cricket family, though they are not technically a cricket. The humpback is striped and the large head is round and dense. They do not have wings. Their hind legs have 2 rows of spines and seem short for a cricket. They are not aggressive, but can bite, painfully, if mistreated or mishandled.

    They are found under rocks or on gravel in valleys or on hillsides, preferring drier climes and loose soil. The tracks they leave behind are unique, created by dragging their large abdomens across the fine particles of soil. They can make a scratching noise. Many new species have been found in California, but their range travels as far east as Nebraska.

    Females often eat their mates. They lay their eggs in soil after making a shallow hole. Nymphs (juveniles) are equally slow-moving.

    Adults and nymphs eat plant roots, other insects, decaying plant matter and potatoes. Sources say it is nocturnal.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
