RES Handbook Vol 2 Part 5a. Homoptera - Psylloidea

The Psylloidea, or jumping plant-lice, are an important component of the hemipterous fauna of many dicotyledenous plants. At present 77 species are known to occur in Britain. Psyllids, in general appearance, resemble miniature cicadas, and vary in size from about 1.5 to 4.5 mm overall in length. They are characterized by their strongly developed hind legs which are adapted for leaping.
