Size: a big one
ran straight into this guy in one of our fields. I don't usually ask for robber fly ID but this one is SO bad looking and we may have found ID . . . but I doubt it. Thank you!

That always impresses in the NE. Ceraturgus cruciatus.

good morning! And thank you so much. I was wondering if you could educate me why it is C. cruciatus instead of fasciatus . . . what is the determining factor? Just in case I run across others (and I think a friend in next town found one, too).
Thank you again!

 
Actually
C. fasciatus is the northeastern species name now. I get those reversed. They were redefined in this paper. And only C. fasciatus is in your area. Very similar in appearance, with distinct distributions.

Vermont is one of the few states where another Ceraturgus knonw as C. similis might also be found. Smaller and with yellow tibiae and clearish wings. It is one of the world's rarest robbers with only five specimens known to science.

Thank you! And despite the odds, we will be looking for that rare one, believe me!
BTW: what are folks to do if they actually come across such a rarity: capture it or photograph it, hopefully beautifully for ID?
Thank you for the response. We're happy about this find!

 
Good photos
Are obviously rarer than specimens of similis. There is a specimen photo on my site from when Jeff had all of the world's Ceraturgus at one time doing that paper. But at a location with multiple similis, it would be good to take one as well. Preferably after photos were taken.

thank you! That paper is pretty good reading (for some reason I enjoy reading where and how bugs are found) . . . so thank you for the advice! (and everything!)
