Spittlebug / nymph - exuviae - spittle - adult

Notes:

The nymphs are fairly sedentary, remaining in their spittlemass for the most part. Clastoptera arborina not undergo the final molt within the spittle, but instead leaves the spittle and molts to the adult stage in the open air.

Spittle: protects the eggs and nymphs. The froth serves a number of purposes. It hides the nymph from the view of predators and parasites, it insulates against heat and cold, thus providing thermal control and also moisture control. Without the froth the insect would quickly dry up. (http://en.wikipedia.org/wiki/Froghopper)
