This pretty ~5 mm fly is perched on a thistle (Cirsium sp). It was photographed June 28 2009 in the Metro Vancouver area of British Columbia, Canada. Surrounding habitat was open meadow/wetland near a small freshwater lake. I wonder if it is Urophora stylata. It was introduced to this area in 1973 as described in this link. www.for.gov.bc.ca...tylata.htm Colin M attached the following image:  [81.3Kb] |

Certainly looks like it, but then again I do not know if there were similar native species.

Yes it is. Certainly Urophora stylata. No other native or introduced species in the New World looking like this. Cirsium certainly must be C. arvense.

Thank you, very interesting. Cirsium could be vulgare, as the fly was introduced to control that species, but I'm afraid I was so intent on the fly that I did not confirm the thistle. In any case, we have plenty of those two thistles around here. |
