These flies were visiting flowers (Yarrow and Dandelion). Are they Anthomyiidae?

6 July 2009, beside a large lake, north of Whitehorse, Yukon, Canada. They varied in size, but the one I measured was 8 mm in length.

Look at the size difference! Yet same sex, same species?

The smaller one's are probable Muscidae, Hebecnema....
The bigger one on the last photo seems Alliopsis (Anthomyiidae)....

Joke, thank-you. Now that you point it out, I see the flies have different venation. Thanks again for your help!
