Beetle that mimics appearance and movement of yellow jacket…

July 2014 was perhaps the most intense yellow jacket season we’ve ever experienced at Angelo. On July 17, 2014, Casey Huckins and Mary Power spotted a “yellow jacket” in a funnel web’s spider web on the road cut banks along the east side of Wilderness Lodge Road, between Skunk Creek and Elder Creek.

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. The closest match I (Mary) could find was Typocerus zebra, Zebra longhorn beetle, Cerambycidae, subfamily Lepturinae. 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
