Flightless Fly

What’s This Australian Soldier Fly doing in England???

Dear Kelly,
For now, we are calling this by the oxymoronic name of flightless Fly.  We are certain it is in the order Diptera, but beyond that, we cannot say at this time.  It does not appear to be the flightless Crane Fly Epidapus venaticus that we found pictured on the Earth Life Web Fly Page as the antennae are quite different from the linked drawing.
  We are going to seek some other opinions.

Chen Young provides some information
Hi Daniel,
Your doubt has its merit, this is not a crane fly and I don’t know off hand who she is.  I will need to ask my colleague about this one.  Could you provide me with the information as where this lady is from?  Please double check with your source, my friend does not believe that this fly has an European origin.

Hi Daniel,
My colleague Dr. Martin Hauser from California Department of Food and Agriculture has identified your wingless fly as a primitive soldier fly Boreoides subulatus  (family  Stratiomyidae) from Australia, and they are found only in Australia.  Perhaps your source did not understand the importance of locality of the bugs when come to identification.
I have done a little more checking around and noticed that you had a webpage about this wingless fly.  They might look slight different but I think it is caused by the camera angle and lighting effect.

Thanks so much for the response Chen.  We will try to get some verification from Kelly regarding the location of the sighting, and also if anyone in the area recently returned from Australia.

I looked this up online myself and came to the same conclusion as Martin Hauser, but did not reply because of the locality being the UK rather than Australia.
