Including Capsidae
Mirid Bugs, Capsid Bugs, Leaf Bugs.
Salient features of adults. Terrestrial.
Phytophagous (mostly), or predacious (a few), or phytophagous and blood-suckers (rarely, then not obligate blood-suckers). Small to large; 2–11 mm long (if longer than 8 mm, not scarlet and black); fliers; relatively stout bodied to with narrow-elongate bodies; conspicuously stilt-legged. Head non-linear. Rostrum clearly separated ventrally from the prosternum by a sclerotized gula; 4 segmented. Antennae longer than the head, readily visible from above; 4 segmented; non-aristate. Ocelli absent. Scutellum relatively small. Fore-wings well developed; in the resting insect lying more or less flat over the abdomen; differentiated into a basally thickened and a distally membranous region; with a costal fracture and cuneus; with a clavus. Trochanters apparently two-segmented. Tarsi 3 segmented. Pulvilli absent (?). The abdomen without ventral silvery pubescence.
Delicate, soft-bodied bugs; the last two antennal segments often thinner and more flexible than the first two. Both adults and nymphs with the unique, apparently 2-segmented trochanter.
Taxonomy. Suborder Heteroptera; Cimicoidea.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
