Bingo

Just a quick question, I usually differentiate cercopidae and cicadellidae by the spines on the tibia of cicadellidae. In that picture, they weren't visible, so how did you identify it?

[ptkid]

Well I usually know its cicadellidae if there are vivid colors on the body and the body shape looks like the shape of the order cicadellidae.

Sorry about that. You are right that cicadellidae does indeed have spines, and that specimen probably does too, but the back legs were hidden under the body. Cicadellidae is also skinnier/narrower than cercopidae, which's wings seem to be wider. Cercopidae also usually appears wet (am I the only one?) due to the nature of their larvae. So, spines are the main defining feature, but when they're hidden, I use size.
