Found, of course, on a dogwood, in this case red-osier dogwood. While the spittle cases were frequent, I saw only a few adults. The spittle of this species seems much thicker and waxier than that of many other spittlebug species. Judging from the look of this one, it may be the fourth instar, but I don't know for certain. These cases are made by the nymphs emitting a white secretion from their behinds, and are designed to keep them moist and provide protection.
