Hyphydrus ovatus is a species of diving beetles in the family Dytiscidae. [1] [2]
Hyphydrus ovatus can reach a length of 4.5–5 millimetres (0.18–0.20 in). The body is rust-red, sometimes with indistinct spots. Males have brilliant colors, and the females matt.
This species is present in most of Europe, in the East Palearctic ecozone and in the Near East. [3]
The Dytiscidae – based on the Greek dytikos (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between 1 and 2.5 cm (0.4–1.0 in) long, though much variation is seen between species. The European Dytiscus latissimus and Brazilian Megadytes ducalis are the largest, reaching up to 4.5 cm (1.8 in) and 4.75 cm (1.9 in) respectively. In contrast, the smallest is likely the Australian Limbodessus atypicali of subterranean waters, which only is about 0.9 mm (0.035 in) long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera.
Baculites is an extinct genus of heteromorph ammonite cephalopods with almost straight shells. The genus, which lived worldwide throughout most of the Late Cretaceous, and which briefly survived the K-Pg mass extinction event, was named by Lamarck in 1799.
Styracosaurus is an extinct genus of herbivorous ceratopsian dinosaur from the Late Cretaceous of North America. It had four to six long parietal spikes extending from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to 60 centimeters long and 15 centimeters wide. The function or functions of the horns and frills have been debated for many years.
Achelousaurus is a genus of centrosaurine ceratopsid dinosaur that lived during the Late Cretaceous Period of what is now North America, about 74.2 million years ago. The first fossils of Achelousaurus were collected in Montana in 1987, by a team led by Jack Horner, with more finds made in 1989. In 1994, Achelousaurus horneri was described and named by Scott D. Sampson; the generic name means "Achelous lizard", in reference to the Greek deity Achelous, and the specific name refers to Horner. The genus is known from a few specimens consisting mainly of skull material from individuals, ranging from juveniles to adults.
Brachyceratops is a dubious genus of ceratopsian dinosaur known only from partial juvenile specimens dating to the late Cretaceous Period of Montana, United States.
Neottia ovata, the common twayblade or eggleaf twayblade, is a terrestrial orchid widespread across much of Europe and Asia
Lagurus is a genus of Old World plants in the grass family, native to the Mediterranean Basin and nearby regions, from Madeira and the Canary Islands to Crimea and Saudi Arabia. It is also naturalized in Australia, New Zealand, the Azores, Ireland and Great Britain, and scattered locations in the Americas. The only known species is Lagurus ovatus, commonly called hare's-tail, hare's-tail grass or bunnytail. It is also grown as an ornamental plant for its attractive flower panicles.
Planorbarius corneus, common name the great ramshorn, is a relatively large species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral or left-coiling shells.
Bithynia leachii is species of small freshwater snail with an operculum, an aquatic prosobranch gastropod mollusk in the family Bithyniidae.
Leptodactylodon ovatus is a species of frog in the family Arthroleptidae. It is found in western Cameroon and extreme eastern Nigeria. Two subspecies are distinguished: Leptodactylodon ovatus ovatus in the westernmost part of the range and Leptodactylodon ovatus orientalis in the east, probably separated by Mount Kupe.
Otiorhynchus is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil and the strawberry root weevil, are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular subject for studies of the evolution of parthenogenesis. The genus is native to the Palearctic region. However, sixteen species were inadvertently introduced to North America and have become widespread there.
Hyphydrus is a genus of diving beetle native to the Palearctic, the Afro-tropical region, the Near East, North Africa. It contains the following species:
Phymorhynchus ovatus is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Trachinotus ovatus, the pompano which is also known as the derbio or silverfish, is a species of ray-finned fish in the family Carangidae, the jacks. It has large, strong fins. It is common in the Mediterranean Sea, and in the Atlantic Ocean from the British Isles and Scandinavia, where it is a vagrant, to the Gulf of Guinea and Angola.
Vetufebrus is an extinct genus of haemospororida in the family Plasmodiidae. At the time of its description the new genus comprised a single species Vetufebrus ovatus known from a single Miocene Dominican amber fossil found on Hispaniola. V. ovatus was vectored by Enischnomyia stegosoma, the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. V. ovatus is the first instance of a Streblidae bat fly as a host for a malarial parasite.
Metagonimus is a genus of trematodes, or fluke worms, in the family Heterophyidae.
Pogonocherus ovatus is a species of beetle in the family Cerambycidae. It was described by Johann August Ephraim Goeze in 1777, originally under the genus Cerambyx. It has a wide distribution throughout Europe, although it has become extinct in several countries, including Luxembourg, Belgium and the Netherlands. It measures between 4 and 6 mm. It contains the varietas Pogonocherus ovatus var. subovatus.
Enischnomyia is an extinct genus of bat fly in the family Streblidae. At the time of its description the new genus comprised a single species, Enischnomyia stegosoma, known from a single Miocene fossil found on Hispaniola. E. stegosoma was the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. The species is host for the plasmodiid Vetufebrus ovatus preserved in its salivary glands and midgut.
Stellasaurus is a genus of centrosaurine ceratopsid dinosaur that lived in Montana during the Late Cretaceous. The type and only species is Stellasaurus ancellae. Its remains have been found in the Late Campanian age Two Medicine Formation, the same geological unit which its relatives Rubeosaurus, Einiosaurus, and Achelousaurus were discovered in.
Hyphydrus intermixtus, is a species of predaceous diving beetle found in India and Sri Lanka.
