Nope these things are the most aggressive things I've ever seen. right out of a horror movie in aggressiveness but thankfully not venomous like yellow jackets. If yellow flies and hornets got mixed the place would be simply uninhabitable. http://entomology.ifas.ufl.edu/creatures/livestock/yellow_fly.htm
Why's this in P&R? Or, are these code words for the likes of larger pests like Obama, Romney, Santorum, Gingrich???
