I found one of these bugs crawling in my home. I just so happens found a the pic u poste on the web while trying to figure out what it is. Have u ever identified it? I live in the California foot hills.



I am making your question public because this creature is a recurring "mystery bug" and my answer may help lots of other people, too.

The insect in the image is plenty familiar to me:  it is a "Jerusalem Cricket," genus Stenopelmatus .  It is not a true cricket, but related to them.  Their nearest living relatives are "king crickets" and "wetas" in the Old World.  Here's more:

Be careful where you get your information on these insects!  Jerusalem crickets are steeped in myth, superstition, and urban legend.  They are also called "potato bugs" and "Child of the Earth" owing to their subterranean habits and enormous, "bald" head.

These insects are harmless, though I do not recommend handling them.  They have strong jaws and can bite hard if mishandled.  Otherwise, they are of no consequence to people.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
