The answer to What Is It Wednesday’s mystery pest is:
Scientific Name: Stenopelmatus fuscus
Common Name: Jerusalem Cricket
Usually referred to as “potato bugs,” even though they do not prefer potatoes and are technically not bugs, they are also called “niña de la tierra” (child-of-the-earth), stone cricket or chaco. Believed by some to be fierce and poisonous, this nocturnal cricket is actually non-aggressive and possesses no poison glands, although its jaws can inflict a painful bite.
