Syrphid -Toxomerus politus - Toxomerus politus - male

Syrphid -Toxomerus politus - Toxomerus politus - Male
Aberdeen, Harford County, Maryland, USA
September 2, 2011
Found the BG link to species pages for the Syrphidae of Ontario. There I found a match in this Toxomerus politus male. They say the "margin of abdomen is alternately black and yellow (as in T. geminatus)", and that's why I thought I'd include the 2nd picture.

It was content to tickle and feed on bits of my arm. After several minutes of one-handed picture taking I shooed it off. I thought it was eating flakes of dried, dead skin, (creepy, then again, great way to exfoliate!) and even tried to get a picture of that, but now read they prefer nectar.

Aha, thanks for the pics (of mouthparts, too)
No wonder it tickled so much. Poor thing really had to go digging to find moisture because my forearm is more like the Bonneville Salt Flats.

Your pictures show longer mouthparts than I remember, so it's good to be reminded. Also, your third picture shows lighter colored mouthparts. That's good to know, because if the mouthparts on T. politus are lighter colored too (hard to see on Ontario page) then that could very well explain what I was mistaking for a flake of dead skin.
