Leafhopper0012 - Thionia

Leafhopper0012 - Thionia
Westford, Crawford County, Pennsylvania, USA

Leafhopper nymph?

Moved from Aplos simplex.

Moved from Thionia elliptica.

Thionia simplex
I have just found a couple of papers describing the various nymphs of Thionia. Apparently, nymphs of T. elliptica are brownish with flat (not pointed) heads, while that of T. bullata have longer heads than either of the other two NE species. So this one is T. simplex.

Moved from Thionia simplex. Moved again after re-reading Dr. Hamilton's comment dated 3/6/08.

Moved from Fulgoroidea.

Rhynchomitra microrhina nymph
According to photos taken in Honduras (see this should be a Dictyopharid nymph - and there is only one such reported from this far north (NY, IL), so this must be the species, even though it is a new state record.

Thionia elliptica
Wrong again!

Another contributer has just sent me a nice photo that is clearly a nymph of Thionia acuta. It turns out that this genus - which always has adults that are gray to brown - has green nymphs with exactly the same paintbrush-like waxy filaments out the tail end. I have checked the literature and found a drawing of the nymph that shows the same rounded wing pads etc. (but of course no color or waxy tail; it is based on a dried specimen in a collection).

This particular species is more darkly marked and has a more pointed head than the only other Thionia in the eastern states, T. simplex.

That's cool, but what about the photo here which you point out as similar below. You wrote that you thought it might be Cedusa. They both sure do look very similar. How do you eliminate Flatid Planthopper as a possibility?

other nymphs
I have seen a paper on Cedusa nymphs, and one of them was photographed recently by Tom Murray. They are short, round, black bugs with wrinkled-looking heads.

Various contributers have turned in all the nymphs of the known northern Flatid genera (Anormenis, Metcalfa, Ormenoides), and none look like this one.

Fulgoroid nymph
These are obviously the same thing as, but darned if I can tell you which one. It is urgent that you watch for adults!
