Trioza urticae, photographed by Shane Farrell.

Belongs within: Sternorrhyncha.
Contains: Psyllinae.

The Psylloidea, jumping plantlice or lerp insects, are a group of small plant-sucking bugs, some of which are notable agricultural pests. They first appear in the fossil record in the Jurassic, where they are represented by the Mesozoic families Liadopsyllidae and Malmopsyllidae (Shcherbakov & Popov 2002). Nymphs commonly inhabit protective structures, such as leaf galls induced in host plants or wax secretions produced from the abdomen.

Characters (from Carver et al. 1991): Adult small. Genal processes commonly developed. Antennae 10-segmented. Three ocelli. Stylets lodged in internal crumena. Hind legs saltatorial; coxae large, fixed; trochanters condylated; saltatorial spines at apices of tibia and first tarsal segment. R, M and Cu of fore wing each usually single branched; peripheral vein present; clavus present. Proctiger well developed; circumanal wax gland ring(s) usually present in female. Sexes similar. Reproduction bisexual. Nymphs non-saltatorial; dorsoventrally flattened; head and prothorax fused. Stylets at rest looped externally at base of labium. Fore wing pad often produced anteriorly as a humeral lobe. Tibia and tarsus fused in instars I-IV; tarsus one-segmented in final instar (V); well-developed arolium usually present. Wax production common, secreted mostly from base of lanceolate setae or sectasetae on abdomen. Eggs pedunculate, with either peduncle inserted into plant tissue or entire egg embedded in plant.
