Hi, my name is Annie. On November 28, 2013 , at 3.50 pm, I noticed this bug on my plant. I have never seen it before and some research work came up with nothing similar at all. I posted a photo on Instagram in the hope someone could tell me, but so far no one does, even though several people have joint me in the research, lol! The back part of its body is bright yellow and black, and it appears to have some water blisters on it’s back., not rain drops as it was a dry and sunny day. The front part of its body is a reddish-dark brown and shiny, it has hairs all over its legs and upper body, and it reared up as in self-defence when I came closer. This bug was found in my garden in Tootgarook on the Mornington Peninsula, Victoria, Australia . The photo I included is taken with a zoom lens, and is pretty much enlarged to its full capacity. Hope it is still good enough for you to identify this bug, lol! Thank you so much for your willingness to look into this kind of things, it is quite fascinating to get to know bugs better!
Kind regards: Annie.

Flightless Female Flower Wasp:  Thynnus species

Flightless Female Flower Wasp: Thynnus species

Dear Annie,
We have several similar images in our archives very similar to this creature, and in 2010, we did significant research and we thought we had identified a photo as a Flightless Female Flower Wasp,
Thynnus apterus.  We are not entirely certain the species is correct, but we are relatively confident with the genus.  Today we found a photo of a mounted pair of Thynnus brenchleyi on the Agriculture of Western Australia website that confirms the genus, if not the species.  There is no female Thynnus apterus pictured on Agriculture of Western Australia.

Dear Daniel.
Thank you so very much for this quick reply! I think the two compare well, although I have to admit that the one I photographed has more and also brighter yellow on the top of its back, but that could possibly have to do with age and/or variety, and quality of the photo!
I am very happy to be able to let this student in America know and tell him your website and the one of Agriculture of Western Australia, so he can have a look for himself.
Again, thank you so very much for your help, it is much appreciated,
With kind regards: Annie j Den Boer.

    This is a species of Catocheilus and most likely undescribed. Thynnus apterus is a very old name and is a Sydney species. Most species now in Catocheilus were in Hemithynnus.
