On closer inspection, the insect turned out to be a beetle–it had hard wing covers (elytra). This mimic looked and moved very much like a yellow jacket, close enough to fool us, almost.

I’m not sure whether they’re native here or not; the species in the photos occur in Tennessee and Texas. Joyce Gross was interested in whether this genus is expanding into

northwestern California, or has been introduced. Next time you see a solitary yellow jacket, look for the split of the elytra down the back.  If anyone knows more about this beetle, we’d be interested.   If you see a bunch of yellow jackets, though, run! (or rather, walk away, quickly) as you may have disturbed a nest.  Always smart to carry benadryl tablets (sold at Geigers in Laytonville), and an Epipen if you think you may be allergic~mep
