Tibicen sp. (davisi)

Not convinced it is T. pruinosus in that part of Florida (too far South). Additionally, the eyes are very light and not characteristic for members of the pruinosus group. Please refer to T. latifasciatus

Nymphs can be hard to id until they emerge and take on the adult form, however, I recommend comparing some of the basics in this image (ready to eclose nymph) to traits seen in T. davisi.
Light eyes (which davisi can have)
Dark pronotal blotches (a common trait in davisi)

Another possibility is Diceroprocta sp. (viridifascia)

Bill, we can move this image to wherever you feel comfy. I'll put it in Tibicen for now...sound good?

Tibicen (?)

Nymphs can be considerably more difficult to id than adult cicadas. Unless you have spent a good bit of time collecting them and observing their emergence, it is not an easy task. I am comfortable with Tibicen sp. nymph for now. I will collect T. davisi nymphs this season and take lots of pic's - I also plan on visiting the NC coast and getting images of. D. viridifascia nymphs as well. Perhaps sometime later this summer we can compare this image to those I obtain and get a better feel for the animal in this pic ;)

Very nice image.

This specimen is just about ready to split it's nymphal skin. You can tell this by noting the very faint brown line that is starting to develop starting from just below the three ocelli, then across the head, pronotum and mesonotum. At this line is where the skin "splits" and the adult Cicada teneral will emerge.
