| | | dog fly
boring I know, but does anyone have any idea what type of fly this is, with a canine/fox face on its back, and very pretty patterns on its wings? |

Hi,
it looks like one of the Tephritidae fruit flies. I don't know what species it is though.

Evening DKP, and welcome to WAB! 
It looks like a female Chaetorellia jaceae, or similar. Boring? I love Tephs!
Take care, Jason  |

boring only in the sense that one should find out for oneself instead of relying on the amazing depth of knowledge available through WAB. I have looked more closely at some other photos and the eyes are indeed a vivid green. The fly was in a meadow full of knapweed, and further research shows that it is now used as a biological control agent for knapweed and related species where they have become invasive. For anyone interested there is a set of close up photos of Tephritidae at this blog by John Smit ( Picasa Web Albums - John T. Smit) |

Glad to hear the fly is being used ( though wasn't too aware of Knapweed being a problem) - the fly is locally-distributed, so it'll be good if they introduce it into new areas. A few other Tephs could do with that sort of help - some are quite scarce, and I'd have thought equally useful in affecting KW/others.

dkp - was looking up more on this fly and found your blog - or rather Spot's blog and his profile - what a clever animal 
I see it's on your WAB profile too if anyone else wants to read it... |

knapweed is an invasive problem apparently in some parts of the USA apparently. By the way presumably the "face " on the back of the fly is part of the mimicry defence ?

I think it's Chaetostomella cylindrica female. Less spots on the thorax.

well I'll try and bear your pet grievances in mind in future
by the way I agree it does look very like Chaetostomella cylindrica. What a fog of knowledge we have encountered (we = Spot and me for the record)
(or Spot and I )
