Class Insecta (Insects)

Order Hemiptera (True Bugs, Cicadas, Hoppers, Aphids and Allies)

Synonyms and other taxonomic changes

Includes Heteroptera (formerly treated as a separate order), Auchenorrhyncha and Sternorrhyncha (the latter two formerly considered parts of Homoptera)

Explanation of Names

Hemiptera Linnaeus 1758

'half-winged'; refers mainly to what is now Heteroptera, whose forewings are part leathery, part membranous

Numbers

~10,200 spp. in almost 1600 genera in our area (>4,000 spp. in Canada); worldwide, ~110,000 spp. described, ~200,000 estimated(1)(2)(3)(4)(5)

Identification

See(6) for discussion of features separating major lineages and a list of latest identification aids.

Auchenorrhyncha & Sternorrhyncha(1):

Many groups covered in spines, setae (hair-like structures), or waxy coverings

Antennae with 3‒13 segments

Wings at rest held rooflike over the body

Beak arises from posterior portion of underside of head

Heteroptera(1):

Often dorsoventrally flattened

Typically two pairs of wings in adult: forewings (hemelytra) are part thick/protective, part membranous

Wings at rest held flat over the body, with membranous parts overlapping

Scutellum prominent

"Beak" arising from front of head

Antennae with 4‒5 segments

Many have thoracic scent glands

Habitat

various, both terrestrial and freshwater

Food

All non-heteropteran members and most Heteroptera feed on plant juices; among Heteroptera, there are many exclusively predatory families (esp. aquatic and semi-aquatic) and major predatory groups in other families. Some suck vertebrate blood.

Life Cycle

metamorphosis incomplete
