Cuerna sp., new month for this inland barrens specialist. Last fall, tried to get material so I had enough to send out for I.D. On the advice of Dr. Hamilton, I did look hard, but found none ready to overwinter. But today, first day after a week of searching (first day to break 72), THERE THEY WERE, and in good numbers. No emergent plants yet however so wonder what they will feed on?- in that this is over a month earlier than the April 2011 material, see But now we should get this finally to species. I was so excited I emailed Dr. Hamilton from the field. This is the HARDEST bug to find and film in the wild. Its jet black color allows it to disappear rapidly, and it is a strong far flier- not much bigger than a grain of rice on top of it. And still, only found on the one dune side. Interesting. I am now closer to knowing this bugger's host plant. Only one odd plant sticks out as a sore thumb in that area. And, this summer- I'll be growing IT AND THIS HOPPER until I figure it out. :0-) Love this hopper. Love a good mystery. Think if I remember, it can be only one of two: C. sayi or C. fenestella.

this looks like the sharpshooters? is color the only difference for the species? gorgeous bug and great pic by the way... coolness.. I need to look for these!

No, color is not the only thing. . .and their can be morphs for the same species. But yes, a "Sharpshooter." Andy Hamilton is the expert. For this animal, there are two very similar species in the U.S. They differ by microscopic characters of the male's genitalia. More to come from Dr. Hamilton I'm sure.


Probably C. fenestella, which is known to occur in southern Ontario and is expected also to occur in "barrens" farther east.

how cool...Ooo I like the black..
