Velvet Water Bug

	Velvet Water Bug Velvet water bugs are members of the family Hebridae. They are semiaquatic insects that live among moss or ponds with an abundance of vegetation, in which they prey on small arthropods. Velvet water bugs are the smallest of the Gerromorpha, and have an appearance of tiny veliids. Hebrids sometimes move across water surfaces, but walk or run rather than skate or scull on the surface. Description Hebrids are small, ranging from lengths of 1.3 to 3.7 mm. They have a characteristic layer of short, dense hairs that cover their entire bodies, except on their abdomens and appendages, from which they derive the common name "velvet water bug". They have tarsi in two segments, with their hing legs shorter than their bodies. Unlike the Veliidae and Mesoveliidae, they are known only as winged forms. These wings, however, may be well-developed to short or lacking. The wing's membrane, when it is present at all, lacks any distinct veins that are common of shore bugs Saldidae. They are ty ...

picture info	Genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

picture info	Sphagnum ''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

	Pronotum The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also Glossary of entomolo ...

picture info	Saldidae Saldidae, also known as shore bugs, are a family of insects in the order Hemiptera (''true bugs''). They are oval-shaped and measure when mature. Typically they are found near shorelines or the marginal growths near freshwater bodies, estuaries, and sea coasts. They can flee by leaping or taking flight. There are about 350 recognized species with the majority from the Nearctic and Palearctic. Many species are found in the intertidal zone and both adults and nymphs of some species like ''Saldula pallipes'' can tolerate submergence at high-tide. Saldidae are predators and scavengers. They pass the winter through egg or adult diapause In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S.

picture info	Veliidae Veliidae is a family of gregarious predatory insects in the suborder Heteroptera. They are commonly known as riffle bugs, small water striders, or broad-shouldered water striders because the segment immediately behind the head is wider than the rest of the abdomen. The genus ''Rhagovelia'' is also referred to as a ripple bug. Veliidae have a specialized body plan that allows them to walk on water and are neuston. Gerridae is another closely related group that is also neuston and both are in the superfamily Gerroidea. Veliidae are smaller however, between . They can be found on ponds, near lake shores, and in rivers worldwide. Some species can also be found on plants near water, in salt water or in mud flats. Life cycle Like all Heteroptera, the Veliidae go through an egg, nymph and adult stage. They have four or five nymphal instars. Both the adults and nymphs live together gregariously, in loose communities and can often be found in large groups. Eggs are usually laid underwater ...

	Gerromorpha The Gerromorpha comprise an infraorder of insects in the "true bug" order Hemiptera. These "typical" bugs (suborder Heteroptera) are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea (infraorder Nepomorpha are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae (water striders). Systematics The eight family families usually recognized are arranged in four superfamilies. The two small or monotypic ones of these are basal lineages; the two larger ones form a more advanced clade. The phylogenetic sequence of superfamilies and families of the Gerromorpha is:ToL (1995) * Mesovelioidea – water treaders Madeoveliidae (sometimes included in Mesoveliidae) Mesoveliidae * Hebroidea – velvet bugs Hebridae ( Hyrcaninae might arguably be ...

	Timasius (bug) Flavius Timasius (died 396) was a general of the Roman Empire, a relative of the Empress Aelia Flaccilla, wife of Emperor Theodosius I (r. 379–395). Biography Timasius was a Roman officer, serving under the command of Emperor Valens (r. 364–378), who survived the Battle of Adrianople (378), in which the Roman emperor lost his life. Emperor Theodosius I appointed Timasius ''magister equitum'' in 386 and ''magister peditum'' in 388.. During his tenure as ''magister militum praesentalis'' (386–395), Timasius was made a consul, along with Promotus, in 389.: "...Fl. Timasius, consul in 389. The name of Timasius' wife, Pentadia, points clearly to a Gallic origin; their son, a young man by 395, was called Syagrius." In 391, he followed Theodosius in the campaign against the barbarians in Macedonia. In that same year, Theodosius was on the verge of annihilating some barbarian units that were hiding in Roman territory when Timasius told him that the troops needed food and rest; the Ro ...
