What kind of bug is this?
The insect in your photo is called a Jerusalem cricket, in the genus Stenopelmatus and family Stenopelmatidae. There are several different species that occur in southern California, all of which look very similar, and I am unable to determine the species from just your photo. Jerusalem crickets are distantly related to grasshoppers and crickets, but they never have wings, don't jump and are different enough to be placed in their own family. These strange looking insects with large heads live in the drier habitats of the western US. They feed mostly on decaying plant matter, usually remaining hidden under rocks or logs during the day and venturing out at night to feed. They are generally harmless, but have large mandibles or jaws that could inflict a painful bite if they are carelessly handled. I have included some links below to websites with more information about these unique insects.
Thank you so much, you're awesome!!
