Common diet items include crickets, locusts, beetles, earwigs, cicadas, ant lions, bugs and ants.
Like most other earwigs, the females care for their young during development, and the larva go through five instars before becoming adults.
Like most earwigs, they are omnivores, and their diet consists of the larvae of leaf-mining insects, as well as certain types of vegetation.
The abdomen of the earwig is flexible and muscular.
Earwigs are among the few non-social insect species that show maternal care.
Black earwigs are active at all times of the day, and prefer wet habitats.
Interaction with earwigs at this time results in a defensive free-fall to the ground followed by a scramble to a nearby cleft or crevice.
Multipurpose insecticides for control of earwigs, grasshoppers, sowbugs and other insects are more common.
