Acanthosomatidae
Acanthosomatidae is a family of Hemiptera, commonly named "shield bugs" and sometimes "stink bugs".There are currently recognized 200 species in 55 genera, making it is one of the least diverse families within Pentatomoidea. The Acanthosomatidae species are found throughout the world, being most abundant in high-latitude temperate regions and in subtropical regions at high altitudes. One of the most well-known species in Acanthosomatidae is the hawthorn shield bug (''Acanthosoma haemorrhoidale''), which is found throughout Europe and also northern Siberia; this species is typically green or brown in color and has a distinctive shape with two projections on its thorax. It feeds on a variety of plants, including hawthorn, rowan, and cherry. Description Acanthosomatidae have heads that are keeled laterally and possess a pair of five-segmented antennae. The mesosternum has a strongly projecting keel. The tarsi of the legs are bisegmented. The second visible abdominal sternite h ...

Pentatomoidea
The Pentatomoidea are a superfamily of insects in the suborder Heteroptera of the order Hemiptera. As hemipterans, they possess a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families (16 extant and 5 extinct). Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs. Description The Pentatomoidea are characterised by a well-developed scutellum (the hardened extension of the thorax over the abdomen). It can be triangular to semielliptical in shape. The antennae typically have five segments. The tarsi usually have two or three segments. Shield bugs have glands that produce a foul-smelling liquid, which is used defensively to deter potential predators. Nymphs have glands on the dorsal surface of the abdomen (dorsal abdominal scent glands). These are often present in adults as well, but adults also develop a pair of glands on the metathorax (third segment of the thorax), ...

Pentatomidae
Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species.Robert G. Foottit, Peter H. Adler ''Insect Biodiversity: Science and Society'', John Wiley and Sons, 2009, As hemipterans, the pentatomids have Hemiptera#Mouthparts, piercing sucking mouthparts, and most are herbivore, phytophagous, including several species which are severe pests on Agriculture, agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial. Etymology The name "Pentatomidae" is from the Greek language, Greek ''pente'' meaning "five" and ''tomos'' meaning "section", and refers to the five segments of their antennae. Pentatomids are generally called "shield bugs" in British English language , English, or "stink bugs" in American English. However, the term shield b ...

Oncacontias Vittatus
The forest shield bug (''Oncacontias vittatus'') is a species of shield bugs endemic to New Zealand. Forest shield bug nymphs prefer feeding on grasses, while adults will eat a variety of New Zealand plants including "hard-leaved" plants like rimu. ''O. vittatus'' was one of the first insects from New Zealand to be described by a European scientist. Taxonomy ''Oncacontias vittatus'', was first described in 1781 by Johan Christian Fabricius as ''Cimex vittatus''. In 1851, ''C. vittatus'' was moved to the ''Acanthosoma'' genus and was renamed as ''Acanthosoma vittatum''. In 1878, ''A. vittatum'' was moved to the ''Anubis'' genus and was renamed as ''Anubis vittatus''. In 1903, the species was independently described again as ''Oncacontias brunneipennis''. In 1906, ''Anubis vittatus'' was moved into the '' Oncacontias'' genus and ''O. brunneipennis'' was recognized as a synonym of ''O. vittatus''.Kirkaldy, G.

Hawthorn Shield Bug
The hawthorn shield bug (''Acanthosoma haemorrhoidale'') is a common European shield bug. Its chief food is haws, the fruit of the hawthorn tree, but adults can overwinter on a diet of leaves, and individuals can be found on many potential food plants, including pedunculate oak, sessile oak and whitebeam. They may grow up to long, and are camouflaged in shades of green and brown. Like many so-called "stink bugs", they may release unpleasant odours when disturbed. Biology The dark green scutellum band is trapezoidal in shape, and extends from the dorsal pronotum to the forewing hemelytral membrane which accounts for the final third of the main body length. The front wings lie flat when the insect is not flying, with the sclerotized pronotum and corium regions coloured dark red. The compound eyes are also red. There is a speckled pigmentation extending from the upper dorsal thorax to the abdominal region. The tarsi are 2-segmented and antennae 5-segmented. As a heteropteran her ...

Sternum (arthropod Anatomy)
The sternum (: sterna) is the ventral portion of a segment of an arthropod thorax or abdomen. In insects, the sterna are usually single, large sclerites, and external. However, they can sometimes be divided in two or more, in which case the subunits are called sternites, and may also be modified on the terminal abdominal segments so as to form part of the functional genitalia, in which case they are frequently reduced in size and development, and may become internalized and/or membranous. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.Sørensen, M. V. et al. Phylogeny of Kinorhyncha based on morphology and two molecular loci. PLoS One 10, 1–33 (2015). Ventrites are externally visible sternites. Usually the first sternite is covered up, so that ventrite numbers do not correspond to sternite numbers. The term is also used in other arthropod groups such as crustaceans, ...

Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects, myriapods, velvet worms and many arachnids to allow air to enter the trachea. Insect respiratory system differs from vertebrates'. The circulatory system plays a relatively minor role in circulating oxygen and removing carbon dioxide; instead, trachea and air sacs in the insect body allow direct gas exchange, and these tracheal tubes eventually connect to the external environment via spiracles. In most species, the spiracles are controlled by motor neurons in the central nervous system. It can be opened and closed in an efficient manner to admit air while minimizing associated physiological costs, such as water loss during respiration. Many sensory stimuli can affect the control of spiracles in insects, e.g. chemosensory (carbon dioxide, oxygen, etc.) or mechanosensory (sound, touch, etc.). It has been shown that during metabolically intensive behaviors, such as flight, insects can dynamically modulate the spir ...

Metapleuron
The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites ( exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) on each side. The metathorax is the segment that bears the hindwings in most winged insects, though sometimes these may be reduced or modified, as in the flies (Diptera), in which they are reduced to form halteres, or flightless, as in beetles (Coleoptera), in which they may be completely absent even though forewings are still present. All adult insects possess legs on the metathorax. In most groups of insects, the metanotum is reduced relative to the mesonotum. In the suborder Apocrita of the Hymenoptera, the first abdominal segment is fused to the metathorax, and is then called the propodeum.

Trichobothria
Trichobothria (singular trichobothrium) are elongate setae ("hairs") present in arachnids, various orders of insects, and myriapods that function in the detection of airborne vibrations and currents, and electrical charge. In 1883, Friedrich Dahl observed that they were deflected by the sound waves from a violin and labelled them 'hearing hairs'. Morphology Unlike the ordinary setae, which are tapered, the trichobothria have the same gauge throughout their length. They fit into the bottom of a broad and deep cup to which connects a membrane with extreme flexibility which adds an extraordinary mobility to them. The least air vibration is able to get them moving and to excite the small group of sensory cells which ensures their innervation. Distribution Trichobothria are present in most orders of the Arachnida, except in Solifugae, Ricinulei and Opiliones The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids, Common name, colloquially known as harv ...

Victor Antoine Signoret
Victor Antoine Signoret (6 April 1816, Paris – 3 April 1889, Paris) was a French pharmacologist, physician and entomologist. In 1845 Signoret gained his doctorate in pharmacology at the University of Paris. His thesis was entitled ''De l'Arsenic considéré sous ses divers points de vue''. Pharmacology made him a wealthy man and he made many collecting trips mainly in Europe but also in Asia Minor. His very important collection is in the Naturhistorisches Museum, Vienna, Austria although there is significant material in La Specola museum in Florence. Signoret worked on Hemiptera, and is considered to be one of the first great students of Coccoidea (mealybugs and scale insect Scale insects are small insects of the Order (biology), order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient g ...s).

Mesosternum
The mesothorax is the middle of the three segments of the Thorax (arthropod anatomy), thorax of Hexapoda, hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum (Dorsum (biology), dorsal), the mesosternum (ventral), and the mesopleuron (lateral (anatomy), lateral) on each side. The mesothorax is the segment that bears the forewings in all winged insects, though sometimes these may be reduced or modified, as in beetles (Coleoptera) or Dermaptera, in which they are sclerotized to form the elytra ("wing covers"), and the Strepsiptera, in which they are reduced to form halteres that attach to the mesonotum. All adult insects possess legs on the mesothorax. In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the Scute#Insects_and_other_arthropods, mesoscutum, or simply "scutum") forms most of the dorsal surface of the thora ...
