Greek Originsof Name:Heteroptera, derived from the Greek hetero- meaning different and ptera meaning wings, refers to the fact that the texture of the front wings is different near the base (leathery) than at the apex (membranous). Pentatomidae Stink Bugs Further to this, the wings of the Heteropterans are usually held flat over the body and the forewings (which are hard and stiff, almost like beetle elytra) have the end part soft and membranous; therefore Heteropteran forewings are referred to as hemi-elytra. Morphological and molecular evidence, however, indicates that the Homoptera and Heteroptera are related at the order level.

Several heteropteran families include species that are predators of other arthropods. In many Hemipterans, the front wings are partly thickened, hard and leather-like, and partly membranous, giving the order the name Hemiptera, from the Greek words hemi, meaning half, and pteron, meaning wing.

Although bed bugs (family Cimicidae) can inflict annoying bites, there is little evidence that they regularly transmit any human or animal pathogen. such as cicadas, the nymphs Gerridae Water Striders The name Hemiptera means For further information on the taxonomy of the order hemiptera see TOL or check out these photos of different hemipteran species. 2022 . The following are the result of my poor scanning and rearranging (to save space) of a few plates from The HEMIPTERA HOMOPTERA (Cicadina and Psyllina) of the BRITISH ISLANDS by James Edwards, F.E.S. Metamorphosis is gradual, the life stages being the egg, nymph, and adult. The insects The Hemiptera (True Bugs) is the largest and by far the most successful of the Hemimetabolic insects (having young that look like wingless adults and a sort of metamorphosis that does notinvolve a pupa).
