Hosta with virus X. Hosta leaves and stems are eaten by deer, rabbits, slugs and snails, and the roots and rhizomes are eaten by voles, all of these can cause extensive damage to collections in gardens.

A leafhoppers' diet commonly consists of sap from a wide and diverse range of plants, but some are more host-specific. Leafhoppers mainly are herbivores, but some are known to eat smaller insects, such as aphids, on occasion. A few species are known to be mud-puddling, but as it seems, females rarely engage in such behavior. Many species are ...
