All of the Homoptera are plant feeders, with mouthparts adapted for sucking plant sap from a wide assortment of trees and wild and cultivated plants. Non-monophyly of Auchenorrhyncha ("Homoptera"), based upon 18S rDNA phylogeny: eco-evolutionary and cladistic implications within pre-heteropterodea Hemiptera (s.l.) The second pair of eyes are ocelli. Order Homoptera: Planthoppers and Treehoppers. recognition of order. Hemipterans have compound eyes and may have as many as three ocelli (photoreceptor organs that receive light through a simple lens). The order Hemiptera is usually subdivided into four suborders: Auchenorrhyncha – the hoppers. Coleorrhyncha – a single family of insects that live among mosses and liverworts. Heteroptera - the true bugs. There are around 32,000 species of sap-feeding insects in this order including: Aphids. Identification. Some species cause devastating damage to major agricultural and economic plants. Since the order is large and diverse, we will often use suborder names when referring to characteristics that are not common to both groups. --- Print References ↑ Helfer, J. R. 1987. Rev.

Hemiptera is the final order in the hemipteroid complex and by far the largest, both in number of species and in ecological importance. As it feeds, it exudes honeydew, which promotes the growth of sooty moulds. The Hemiptera are called 'true' bugs because everyone - entomologists included - tend to call all insects 'bugs'. There is much diversity in the morphology of the order. They are closely related to the true bugs. "Typical bugs" might be used as a more unequivocal alternative, since the heteropterans are most consistently and universally termed "bugs" among the Hemiptera. This activity familiarizes students with the six most populous orders of insects by producing Mini-Books with the name of each order on a separate page, examples of common insects in that order, a picture, identifying characteristics, and an interesting fact. How to know the grasshoppers, crickets, cockroaches, and their allies. The smallest beetle is the fringed ant beetle, Nanosella fungi (family Ptiliidae).

This order is large and diverse and includes groups of insects, which may appear to be unrelated due to their differing appearances. However all hymenopterans share the following characteristics: Two pairs of membranous wings, although some may be wingless such as some species of female wasps and the worker caste of ants. General characteristics: • two pairs of wings • hind wings are membranous • uniformly textured forewings may be either leathery or membranous • when the insect is not flying, its wings fold together roof-like over the back • sucking mouthparts • hemimetabolous metamorphosis (egg — nymph — adult) Aphids are a type of insect that belong to the Aphidoidea superfamily. This is the largest order in the class Insecta with over 250,000 described species. The earlier work was based on nuclear DNA, but more recent phylogenetic analysis using mitochondrial DNA suggest that Homoptera may be a monophyletic group after … The types and functional characteristics of plant-homopteran-ant interactions have been reviewed on a number of occasions (26, 28, 177, 227) and need not ...

Coleoptera, Diptera, Hemiptera, Hymenoptera, Homoptera, Lepidoptera, Odonata, Orthoptera. Today, Hemiptera is the fifth largest insect order, surpassed only by the four major holometabolous orders (Hymenoptera, Coleoptera, Lepidoptera, and Diptera). Key characteristics: Suborder Heteroptera are the true bugs; they have a beak arising from front of the head, long antennae, and two pairs of wings (in most adults). Hemiptera. As their name suggests their wings appear lace-like with many intricate veins across their entire surface. • Mouthparts are of sucking type, but may be modified into sponging type. Psylloidea, which is the least studied group of insects in the order Homoptera. Syst. Most are small, soft bodied insects. Definition. Plant-fluid feeding probably coincided with the origin of Hemiptera and was independently derived in thrips. Adults are the largest members of the Homoptera. (xi) Order Homoptera: Wings entirely membranous; mouthparts arise ventrally on posterior margin of head (hypognathous). Helfer (1987), Mallis (1997) and Triplehorn and Johnson (2005) are good general references for information about this order. Neuroptera: lacewings and antlions. Apical portion is membranous (this type of wing is called hemelytron, or hemelytran if single) Hind wings are completely membranous and shorter than the front wings. Paleontologists do not agree on the exact or relative ages of either the Homoptera or Heteroptera. This means the front wings, called tegmina, are stiff, straight, and not used for flying.The back wings are membranous and are folded like a fan under the front wings when the insect is not flying. While some entomologists consider each group a separate insect order, others feel they have a common origin and classify them as suborders of the order Hemiptera. Recent changes have resulted in the combination of orders Homoptera and Hemiptera into one order called Hemiptera. Key Difference – Homoptera vs Hemiptera. Order: Neuroptera The common names are the Antlions , and Lacewings . Homoptera and Hemiptera are two insect groups. The size ranges from very minute to larger forms.

The Psocoptera are tiny insects that have either four wings, two wings or none at all. It remains one of the most abundant and diverse groups of plant-feeding insects. Ecol. Insect scientists (Entomologists) categorize groups of living entities as how they are related through the Theory of Evolution. 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. Two large groups of Homoptera are (1) the cicadas and leafhoppers, and (2) the aphids, scale insects and mealybugs.
