The link below is not actually a bee, but a type of wasp. It is large, has yellow and black backside, brownish-orange wings. It stings a cicada and buries it in the ground, paralized but alive and plants its eggs with it, where they hatch and have something to eat. Yuck. I think that the females can sting but usually use their "stinger" for ova-positioning. Males just buzz you to defend the territory. Thought this might be what you have seen. hortster |
