I only saw this fly one time - this photo was taken near Chicago, IL USA on May 25. Thanks for any help with ID. I love the Syrphidae!

Hello Bruce, This is indeed a female of Toxomerus. The picture is perfect for identification, because the key characteristic feature of the genus Toxomerus is the triangular emargination on the eye margin at or above level of insertion of the antenna. This is clearly visible in this picture! North of Mexico there are 17 species of this genus, so for the species it is a bit more difficult. Maybe somebody with more knowledge of American Syrphids can give more information about the species! Greetings, Greetings, Gerard Pennards |
