My back yard is overrun with tenebrionid beetles (genus Eleodes), aka stink beetles. This is in Southern California, early May 2010. My wife Kathy is behind the camera making comments from the peanut gallery.

Here is a picture of a larger version I took a couple years ago:

This was a good sized female who was a little worse for wear (note the dent in her elytron/back). She was ovipositing in a dirt road.
