“Homoptera” is an abandoned name formely used for all the hemipterans except the Heteroptera. Classification of Hexapoda (Insects) The subclass Pterygota is divided in two divisions: Exopterygota (= insects with a simple metamorphosis, without pupal stage) Endopterygota (= with a complete metamorphosis, including a pupal stage). The Heteroptera are a group of about 40,000 species of insects in the order Hemiptera.They are sometimes called "true bugs", though that name more commonly refers to the Hemiptera as a whole. A large order of insects characterized by having the mouth parts adapted to piercing or suckingIt is comprised of four suborders: HETEROPTERA, Auchenorrhyncha, Sternorrhyncha, and Coleorrhyncha pair of wings. Hemiptera (n.). This group includes leaf aphids, and cicadas hoppers. Classically, Hemiptera is comprised of two suborders: Homoptera and Heteroptera. provided by the The head and proboscis can flex forward. Geological Society 1. plant bugs; bedbugs; some true bugs; also includes suborders Heteroptera (true bugs) and Homoptera (e.g., aphids, plant lice and cicadas) 2. Also Know, what does Exopterygota mean? The Homoptera and Hemiptera are separated into two separate orders, principally . Confused? Hemiptera is the largest order of hemimetabolous insects (not undergoing complete metamorphosis; though some examples such as male scale insects do undergo a form of complete metamorphosis ) containing over 75,000 named species; insect orders with more species all have a pupal stage (i.e. Hemiptera page from the Tree of Life These two orders were then combined into the single order Hemiptera by many authorities, with Homoptera and Heteroptera classified as suborders. Hemiptera. General Summary of Homoptera The Homoptera includes a large number of different forms ranging in size from the usually microscopic Coccidae to the large tropical lantern bugs (Fulgoridae) and the cicadas, which may attain 5 cm. These two orders were then combined into the single order Hemiptera by many authorities, with Homoptera and Heteroptera classified as suborders. The 2 groups can often be distinguished easily, as the Heteropterans have a large pronotum and a … Homoptera One of the two prime divisions of hemipterous insects founded by Latreille in 1817; a suborder of Hemiptera, contrasted with Heteroptera. or . The aquatic and semiaquatic Heteroptera, consisting of the infraorders Leptopodomorpha, Gerromorpha, and Nepomorpha, comprise a significant component of the world's aquatic insect biota. The Heteroptera are a group of about 40,000 species of insects in the order Hemiptera.They are sometimes called "true bugs", though that name more commonly refers to the Hemiptera as a whole. Other entomologists, while recognizing the proximity of relationship between these two groups, consider that the relationship is of superorder value and that features separating…. we have called the Hemiptera and use Hemiptera for the Heteroptera. Major Families. C Wood: I thought it might help to have a description of each since many here are amateurs. 1896. Classically, Hemiptera is comprised of two suborders: Homoptera and Heteroptera. the order Hemiptera. They are all true bugs and have sucking mouth parts. Non-monophyly of Auchenorrhyncha ("Homoptera"), based upon 18S rDNA phylogeny: eco-evolutionary and cladistic implications within pre-heteropterodea Hemiptera (s.l.) The key difference between Homoptera and Hemiptera is that the Homoptera is a plant feeder that uses its antennae to suck the plant juice to fulfill its nutrition requirement while Hemiptera is both a plant and a blood feeder. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. However, according to previous molecular phylogenetic studies based on 18S rDNA, Fulgoromorpha has a closer relationship to Heteroptera than to other hemipterans, leaving Homoptera as paraphyletic. In members of the second group, Heteroptera, the rostrum is relatively long (3-4 segments) and arises near the front or lower front of the head (prognathous or hypognathous). In 1999, however, we did not observe higher numbers of E. fabae in the uncut strips. Little considered is the fact that certain Homoptera (e.g., scale insects and whiteflies) pass through a stage in their development resembling complete metamorphosis. Homoptera and Heteroptera comprise a large insect assemblage, the Hemiptera. Keeping this in consideration, is hexapoda an Exopterygota? These parameters were estimated using the method of maximum likelihood (PROC CATMOD, SAS Institute 1989).If P 1 > 0 and P 2 < 0, the proportion of prey eaten is initially positively density-dependent, thus describing a type III functional response. The Coleorrhyncha extend back to the Lower Jurassic. In contrast to the Hemiptera, homopteran mouthparts arise further back on the underside of the head. The mouthparts vary considerably in detail. rest of the first pair and the second pair are membranous. Lampe for making them available to us. 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. Coccids were once the source of the crimson dye kermes. Heteroptera The true bugs have forewings that are hardened at the base and membranous at the tips. The Homoptera are close relatives of the Hemiptera and also have piercing-sucking mouthparts. In the Heteroptera the beak arises from the front of the head and is movable, while in the Homoptera the beak is fastened rigidly to the head, cannot be moved, and appears to arise from the dorsoventral portion.

Those who classify these two groups as suborders of the Hemiptera place only minor emphasis upon these distinct differences. water bugs, from the This group includes leaf aphids, and cicadas hoppers. This should give you a general idea about the incredible diversity we see within this order. 1. The Heteroptera first appeared in the Triassic. that part of the first pair of wings is toughened and hard, while the The picture at the top of the page depicts The fossil record of hemipterans goes back to the Carboniferous (Moscovian). Homoptera. hemielytra. The forewings of heteropterans are generally divided into basal and apical halves of different texture. They are all true bugs and have sucking mouth parts. Homopteran forewings, on the other hand, are generally of similar texture for their full length. . With the cicadas are the leafhoppers, treehoppers and froghoppers, all active insects. Homoptera One of the two prime divisions of hemipterous insects founded by Latreille in 1817; a suborder of Hemiptera, contrasted with Heteroptera. Scent glands are present in all terrestrial and some aquatic nymphs and adults of the Heteroptera. also have modified piercing and sucking mouthparts; some suck plant juices and Incomplete metamorphosis. Homopterans are a paraphyletic group, now divided into three monophyletic orders/suborders: Sternorrhyncha (White flies, scale insects, aphids and jumping plant lice), Auchenorrhyncha (Leaf hoppers, plant hoppers, cicadas), and the relict group Coleorrhyncha (Grimaldi, D. & Engel, M. 2005). It contains a very large number of bugs of the greatest diversity in form, normally with large wings, and hemielytra of like texture throughout (whence the name), which are usually folded in a slanting direction. Heteroptera are more closely allied (evolutionarily) with Coleorrhyncha than with Homoptera, although some have recently argued that the closest relatives of Heteroptera are certain homopteran groups. This system, however, places only minor importance on the distinct differences in structure and in details of metamorphosis that have led some workers to propose separate ordinal rank for Homoptera and Hemiptera and abandonment of the term Heteroptera. Aphids and Coccoids appear in the Triassic. Florissant Shale of Colorado. Homoptera includes Cicadomorpha, Fulgoromorpha and Sternorrhyncha. All the Homopterans and many of the Heteropterans feed on plant juices, though many of the Heteroptera are predatory – and some are useful as controllers of plant pests. hemielytra. The Homoptera. 1851. Homoptera and Hemiptera are two insect groups. They sit flat over the abdomen hiding the membranous hind wings. The key difference between Homoptera and Hemiptera is that the Homoptera is a plant feeder that uses its antennae to suck the plant juice to fulfill its nutrition requirement … Obtaining true bugs. within the group Heteroptera; others use the name Heteroptera for what "Typical bugs" might be used as a more unequivocal alternative, since the heteropterans are most consistently and universally termed "bugs" among the Hemiptera. At repose these wings are held at a rooflike angle over the abdomen, overlapping only slightly on the inner apical margin. species in all. Westwood. Major differences 1.
