Micropezidae - Stilt-legged Fly? - Micropeza corrigiolata - female

Micropezidae - Stilt-legged Fly? - Micropeza corrigiolata - Female
Stratford, Queens County, Prince Edward Island, Canada
July 3, 2009
I believe I may have submitted this to ID Request in 2009. If so, it has been overlooked; if not, here it is. (Maybe it was frassed.)

On browsing thru the flies, I came upon the Micropezidae - Stilt-legged Flies, and this fits the bill. It was on shoreline vegetation beside a river, opposite the City of Charlottetown, PEI.

More widespread than this
John Klymko, co-ordinator of the Maritimes Butterfly Atlas, made the following comment:

Saw the thread on BNB [Birding New Brunswick] about the micropezid you found for PEI, nice record!. That species is common here in Sackville [in southern NB near the border with NS] in vegetable gardens where they seem to take to the beans and peas. When I first encountered them last year I didn't know what sort of micropezid they were so I sent Morgan Jackson, with whom I did my MSc, some specimens and he concluded they were the introduced species. The species must also be present in NS, and is probably in Maine as well.

Micropezidae
Hi Chris, you're correct, this is a micropezid. It's a European species (Micropeza corrigiolata) which was only recorded from New Brunswick as far as I know, so this is an important record. This species is considered a minor pest of peas.

 
Non-native
Morgan: can you please tell us a little more about this species and how this image was IDed? I want to add it to List of non-natives. Thanks.
Chris, if you have other images, it may worth adding them.

 
Micropeza corrigiolata (L.)
This is the only Micropeza species known to occur in eastern Canada, and is morphologically distinct from North American native species (male lacks genital graspers, head and body nearly entirely black). Although widespread in Europe, it had only been recorded from 2 localities in New Brunswick (St. John & Moncton areas).

Thanks
Great!
