What's That Bug? does not endorse extermination

Black bodied, blue winged wasp like bug
Hey bug people,
I’ve found lots of bugs on your site but this one has got me so far. Lots of these fly around our tomatoes here in Australia. I’ve had tomatoes before but never saw these before. They seemed too big to be a black flower wasp (that and they leave our regular flowers alone). They have bright blue wings and eyes with black bodies. They constantly move so this was a clear a shot as I could get. Thanks
Peter

Hi Peter,
We suspect these are Blue Flower Wasps or Hairy Flower Wasps, Discolia soror, based on images posted to the Geocities Website. They are in the family SCOLIIDAE Scoliidae. Adult Blue Flower Wasps are nectar feeders and the larvae feed on Scarab Beetle Grubs. The female wasp locates the beetle grubs in the soil, digs down and lays an egg on the grub. The Csiro Website (which refers to this species as the Black Flower Wasp) indicates: “Black flower wasps are solitary and do not make communal nests. However, in mid to late summer, they often form small swarms flying low over an area of turf, a compost heap or around a shrub. The adults can also be seen taking nectar from flowers.”

    Pretty sure I killed one of these in Wisconsin. Are they like the yellow and black wasps? Do they sting? Where can I find out more information about these?

      The Blue Flower Wasp is native to Australia, and to the best of our knowledge, they have not been reported from Wisconsin. Additional information on the Blue Flower Wasp is available on Csiro. You may also follow the links on our posting.
