Within Paraneoptera, Hemiptera is most closely related to the sister clade Thysanoptera.  The name "true bugs" is often limited to the suborder Heteroptera. Not all insects are bugs. Insects have a high protein content and good food conversion ratios, but most hemipterans are too small to be a useful component of the human diet. 13 0 obj
Wing development is sometimes related to environmental conditions. Q5@FS#xLf JXC;TE`JDp%WG", , Many aphids are parthenogenetic during part of the life cycle, such that females can produce unfertilized eggs, which are clones of their mother. ;2+pK_( l1a/-UH6@r2%w\Q9W^hmhZxbH q(v  The first known hemipteran to feed in this way on vertebrates was the extinct assassin bug Triatoma dominicana found fossilized in amber and dating back about twenty million years. Aside from the mouthparts, various other insects can be confused with Hemiptera, but they all have biting mandibles and maxillae instead of the rostrum. These include the water boatmen, pond skaters, and giant water bugs. , The fossil record of hemipterans goes back to the Carboniferous (Moscovian). Most Heteroptera also feed on mesophyll tissue where they are more likely to encounter defensive secondary plant metabolites which often leads to the evolution of host specificity. In this section, there's a wealth of information about our collections of scientific specimens and cultural objects. <>
Aphids and whiteflies can sometimes be transported very long distances by atmospheric updrafts and high altitude winds.
Beetles have pinching jaws (mandibles); bugs, piercing, sucking mouthparts usually folded back against the underside. endobj
In some groups of Hemiptera, there are variations of winged, short-winged, and wingless forms within a single species. In aphids, both winged and wingless forms occur with winged forms produced in greater numbers when food resources are depleted. Warming is correlated with the severity of potato leafhopper infestation, so increased warming may worsen infestations in future.

Ants such as the yellow anthill ant, Lasius flavus, breed aphids of at least four species, Geoica utricularia, Tetraneura ulmi, Forda marginata and Forda formicaria, taking eggs with them when they found a new colony; in return, these aphids are obligately associated with the ant, breeding mainly or wholly asexually inside anthills. Praying mantids maybe be confused with some bugs that have raptorial legs for example water scorpions (Family Nepidae), fishkiller bugs (Family Belostomatidae), and some assassin bugs (Family Reduvidae). Wing buds grow in later stage nymphs; the final transformation involves little more than the development of functional wings (if they are present at all) and functioning sexual organs, with no intervening pupal stage as in holometabolous insects.

All such young are females (thelytoky), so 100% of the population at these times can produce more offspring. Silverfish belong to the Order Zygentoma (formerly Thysanura). <>

Beetles have hardened forewings that meet along a midline and mouthparts for chewing or munching, whilst burrowing bugs have sucking tube mouthparts and their forewing has a membranous tip with veins, with the tips of the forewing overlapping at rest. The diet is typically plant sap, but some hemipterans such as assassin bugs are blood-suckers, and a few are predators. For piercing and sucking, do not have visible palps (mouthparts that look like a 'chain of beads'). The green/red flash coloration earns the insect the name of stop and go cicada. , Cicadas have featured in literature since the time of Homer's Iliad, and as motifs in decorative art from the Chinese Shang dynasty (17661122 B.C.).  The antennae in Hemiptera typically consist of four or five segments, although they can still be quite long, and the tarsi of the legs have two or three segments.

Other insect orders with mouthparts modified into anything like the rostrum and stylets of the Hemiptera include some Phthiraptera, but for other reasons they generally are easy to recognize as non-hemipteran. , A striking adaptation to a very dilute diet is found in many hemipterans: a filter chamber, a part of the gut looped back on itself as a countercurrent exchanger, which permits nutrients to be separated from excess water. For example they may fly away, run or move out of the line of sight, remain still, drop to ground as if dead, flash warning colours, release noxious chemicals, bite, or swim away and dive. , The below cladogram shows Hemiptera's placement within Paraneoptera, as well as how Hemiptera's four suborders are related. , Hemipterans are hemimetabolous, meaning that they do not undergo metamorphosis, the complete change of form between a larval phase and an adult phase. <>

Others such as Carpocoris purpureipennis secrete toxic fluids to ward off arthropod predators; some Pentatomidae such as Dolycoris are able to direct these fluids at an attacker.  The residue, mostly water with sugars and amino acids, is quickly excreted as sticky "honey dew", notably from aphids but also from other Auchenorrhycha and Sternorrhyncha. stream
