We Who Are About to Hop Salute You
I am not very sure on this identification, but I think this treehopper is none other than Entylia carinata. Either way, it has very nice form on its salute. Either that or its eye is really itchy.
According to BugGuide.net, carinata means "shell-formed/shaped; like a keel/hull." And I suppose they do look a bit (just a bit) like a cap-sized boat; the hump (or thorn-like structure) I guess is would signify a rudder.
And with that, this ship be sailing. :)
