You got it again, Ken. Thanks for the ID. It's nice that Mark was able to photograph that fly right through the wings. The wings on mine seemed darker. Thanks again!

Hey, I was just comparing the Data tab on this fellow with the distribution chart on the Canadian Journal of Arthropod Identification. http://cjai.biologicalsurvey.ca/mylmst_23/mylmst_23_499.HTM

Both had zero entries for Michigan. Now there are 4 images in the Data tab - the ones I just submitted. :-)

Hooray!

You might find diptera.org's Nomenclator to be a useful source of range data. For R. nasica, see here:

http://diptera.org/NomenclatorDetail.php?Recn=480959

"Range: (NE: NE) Manitoba To N.b., S. To Colorado And Georgia"

(NE = Nearctic)

Thanks Kelsey, so that website must have had someone who saw one of these in Michigan. In Michigan Butterflies and Skippers (Nielsen), they have a map of all the counties reporting the relevant insect. At least one of the butterflies (Polygonia interrogationis) doesn't appear in Calhoun County, whereas I see them not infrequently and even found a caterpillar in my yard a month or so ago. Someone said it didn't mean there WERE no P.interrogationis in the county, but nobody had bothered to report it.

Thanks again for the resource. I do really like Bugguide's map, state/province by state/province, of sightings in the Data tab.
