The Mormon cricket shows a marked preference for forbs, but grasses and shrubs such as sagebrush are also consumed. [9] Mormon crickets also eat insects, including other Mormon crickets, especially individuals that have been killed or injured by automobiles or insecticides. Cannibalistic behavior may be a result of protein and salt deficiency.
Jerusalem crickets seem unable to hiss by forcing air through their spiracles, as some beetles and cockroaches do. Instead, the few Jerusalem crickets that do make sound rub their hind legs against the sides of the abdomen, producing a rasping, hissing noise. [6] This hiss may serve to deter predators rather than to communicate with other crickets.

They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs.

[3] The damage to the crops in 1848 was due to frost, crickets, and drought, and the gulls only had a minor impact on one of those ...
Insects reproduce at a faster rate than beef animals. A female cricket can lay from 1,200 to 1,500 eggs in three to four weeks, while for beef the ratio is four breeding animals for each market animal produced. This gives house crickets a true food conversion efficiency almost 20 times higher than beef. [28]
