Philanthus gibbosus

This is quite the striking wasp with its pitted black and yellow abdomen. It hardly sits still for a second
and I chased this one around for quite awhile.  They are called beewolves because they prey on bees.
I saw these wasps more than any others in the Jordanelle wetlands this day.  © Carol Davis, 8-21-2011

According to, adult beewolves feed on nectar but the larvae feast on bees
 (given to them by their mother).  Also, according to this article, the mother also
cultivates a bacteria in her antennae that she applies to brood cells to keep
out harmful bacteria.  © Carol Davis, 8-26-07,
