Insects of Britain and Ireland: the families of Hemiptera
Salient features of adults. Terrestrial.
Phytophagous (on a variety of plants, with two very common species on thistles; some producing galls). Tiny, or small; 2–5 mm long; fliers; relatively stout bodied. Rostrum clearly separated ventrally from the prosternum by a sclerotized gula. Antennae longer than the head, readily visible from above; 4 segmented; non-aristate. Ocelli absent. Thorax conspicuously crested, or not crested. Fore-wings well developed; in the resting insect lying more or less flat over the abdomen; more or less uniform in texture (though the corium is more or less detectable); with a clavus; with conspicuously raised, reticulate venation; finely reticulate or areolate throughout. Hind coxae mobile; rotatory. Claws all apical. Pulvilli present. The abdomen without ventral silvery pubescence.
Fore-wings more or less uniform in texture, glassy, with a fine reticulum of raised veins; pronotum similarly patterned; the scutellum and clavus concealed by a triangular extension from the posterior lobe of the pronutum.
