(3)Life Cycle
After the nymph molts for the final time, the resulting adult insect leaves the mass of "spittle" and moves about actively. The "spittle" is derived from a fluid voided from the anus and from a mucilaginous substance excreted by epidermal glands. Nymphs wander away from their spittle masses, and either start new ones, or enter those of other nymphs. Aphrophora nymphs hold the record, of one spittle mass over a foot long containing about 100 individuals! --A.K.G. Hamilton
