Vinegar Fly - Drosophila - Female
Richmond Hill, York Region, Ontario, Canada
July 19, 2007
Sorry for the blurriness. A gravid female, she sat on the same spot on the leaf and did not move the whole time I spent shooting other insects on the same group of plants. Not sure if an ID is possible from this ... but it sure looks like one of those laboratory fruit flies.

Drosophila, seconded
But I've been wrong on these so often that I should quietly retire to lick my wounds. See here, Stephen: http://mamba.bio.uci.edu/~pjbryant/biodiv/diptera/Fruit%20fly.htm

Thanks Ron
Not surprisingly, Drosophila are quite a tough group actually. I initially hesitated at melanogaster because the abdominal tergites looked differently patterned. So I stuck with "laboratory fruit flies", since I recall that they do use species other than melanogaster :-)
