The nymph puts together globs of honeydew to make a protective cover called a lerp. It's not permanently attached and can move around if it needs to, sometimes using and expanding lerps abandoned by others. Both nymphs and adults seem to prefer feeding near others or their species. The adult males stridulate ("sing") to attract females. Depending on the weather, there can be more than one generation per year.
The nymph lives under the lerp, a protective shell of gelatinous honeydew. --Dennis Haines, 28.ii.2009
