Entylia Carinat Treehopper with nymph under its wings? - Entylia carinata
Hopewell Township, Mercer County, New Jersey, USA September 21, 2014 Size: ~ 5 mm
Not sure what's going on here. The adult moved around quite a bit and it was difficult to photograph. What appears to be a nymph, didn't appear to move at all.
