I have collected a single specimen of Physiphora demandata from Shropshire in the United Kingdom. The only reference I can find to it is in Colyer & Hammond's Flies of the British Isles, where it states that the species is "rarely recorded". I have certainly never encountered it before. Can anyone advise what the likely status of this fly is in the UK?

If it is anywhere similar to the Netherlands, then it probably can be described as uncommon but widespread. I think the main thing is that it is rarely collected. My gut feeling says it is probably not as uncommon as it a ppears from recorded material because it is underrecorded.

Thanks Paul, I think you could be right. It breeds in manure, which there is no shortage of, so there is no apparent reason for it to be rare. It is a difficult fly to see, it seems to merge into what ever it is resting on. I just happened to notice this one resting on a fence post, when I was searching for hole nesting aculeates on the post.

Just to substantiate my point a little: This afternoon a fished a dead female of Physophora alceae (the current name of the species) from our daughter's children's pool in the garden. I live at the edge of a reasonably sized city in the northwest of the Netherlands without any remarkable nature reserves in the very close vicinity. In a 2 km radius we have city, parks, some industrial estates and agricultural areas. Paul - - - - Paul Beuk on https://diptera.info |

Well, like it turns out, sometimes you do not even have to seek to find it...
