Maybe Drepanaphis

Drepanaphis are pretty distinct but you need to check the siphunculi, which you can't see from this angle. They would have "vasiform" or vase-shaped siphunculi. The arrangement and length of those dorsal spines are used to ID species.

Were there maples nearby? They feed on the genus Acer.

There are some other genera that might have big dorsal spines, but their siphunculi tend to be reduced.

Thank you Natalie.

I have just added several additional photographs that I took today: 1) The dorsal view of the posterior end and 2) the lateral view of the posterior end. I hope these show the details that you need.

Yes, there were red maple trees close by, but I was using the sweep net in the grasses several yards away from them.

Yep. Definitely Drepanaphis.

I'm not sure on species, I've only collected a few and there are several in the genus, but definitely Drepanaphis. I'll try to remember to take a look in my key and see if I can ID species.
