The lesser silver water beetle (Hydrochara caraboides) is a species of water scavenger beetle (family Hydrophilidae).
The beetle is about 15 millimetres (0.6 in) long and, despite the name, is actually black in color. It traps air with the hairs on the underside of its body in order to breathe below water, and it is this silver looking bubble of air that gives the beetle its name. [1]
H. caraboides has a wide distribution across Europe. [2] In the United Kingdom, it is only found in the Somerset Levels, Cheshire and north-east Wales. It is classified as an endangered species, protected under Schedule 5 of the Wildlife and Countryside Act 1981. [1]
The northern population cluster currently consists of around 45 breeding pools, several being ditches, most of which have a floating raft of densely matted vegetation at their centre, and an area of shallow open water containing isolated stands of emergent vegetation. The effect from cattle poaching is considered crucial for the beetle's ability to breed successfully at these water bodies.
Beetles are insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
The greater scaup, just scaup in Europe or, colloquially, "bluebill" in North America, is a mid-sized diving duck, larger than the closely related lesser scaup. It spends the summer months breeding in Alaska, northern Canada, Siberia, and the northernmost reaches of Europe. During the winter, it migrates south to the coasts of North America, Europe, and Japan.
The northern parula is a small New World warbler. It breeds in eastern North America from southern Canada to Florida.
The Haliplidae are a family of water beetles that swim using an alternating motion of the legs. They are therefore clumsy in water, and prefer to get around by crawling. The family consists of about 200 species in 5 genera, distributed wherever there is freshwater habitat; it is the only extant member of superfamily Haliploidea. They are also known as crawling water beetles or haliplids.
Dytiscus is a Holarctic genus of predaceous diving beetles that usually live in wetlands and ponds. There are 26 species in this genus distributed in Europe, Asia, North Africa and North and Central America. They are predators that can reduce mosquito larvae.
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Histeridae is a family of beetles commonly known as clown beetles or Hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other Hister beetles, they must be isolated when collected.
Shapwick is a village on the Polden Hills overlooking the Somerset Moors, in the Sedgemoor district of Somerset, England. It is situated to the west of Glastonbury.
The River Brue originates in the parish of Brewham in Somerset, England, and reaches the sea some 50 kilometres (31 mi) west at Burnham-on-Sea. It originally took a different route from Glastonbury to the sea, but this was changed by Glastonbury Abbey in the twelfth century. The river provides an important drainage route for water from a low-lying area which is prone to flooding which man has tried to manage through rhynes, canals, artificial rivers and sluices for centuries.
Shapwick Heath is a 394.0-hectare biological Site of Special Scientific Interest and national nature reserve between Shapwick and Westhay in Somerset, notified in 1967. It is part of the Brue Valley Living Landscape conservation project. The project commenced in January 2009 and aims to restore, recreate and reconnect habitat. It aims to ensure that wildlife is enhanced and capable of sustaining itself in the face of climate change while guaranteeing farmers and other landowners can continue to use their land profitably. It is one of an increasing number of landscape scale conservation projects in the UK.
Tealham and Tadham Moors is a 917.6 hectare biological Site of Special Scientific Interest south of Wedmore in Somerset, notified in 1985.
Phumdi, also known as Phumthi or simply Phum, are a series of floating islands, exclusive to the Loktak Lake in Manipur state, in northeastern India. They cover a substantial part of the lake area and are heterogeneous masses of vegetation, soil and organic matter, in different stages of decay. The largest single mass of phumdi is in the southeastern part of the lake, covering an area of 40 km2 (15.4 sq mi). This mass constitutes the world’s largest floating park, named Keibul Lamjao National Park. The park was formed to preserve the endangered Eld's deer subspecies, called sangai in the Meitei language, indigenous to this area.
Cychrus caraboides is a species of ground beetle.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with hardened wing covers were brought together under the name Coleoptera.
Platycerus caraboides is a species of stag beetle belonging to the family Lucanidae, subfamily Lucaninae.
Gowy Meadows Nature Reserve is a 165.8-hectare (410-acre) nature reserve near Ellesmere Port, Cheshire, England. It consists of low-lying meadows immediately to the east of the River Gowy near its confluence with the River Mersey, south of Stanlow Oil Refinery and west of the village of Thornton-le-Moors. It is managed by the Cheshire Wildlife Trust on behalf of the landowner, Shell UK, and was founded in 2002. The M56 motorway runs along the southern edge of the reserve.
Hydrophilus piceus is a species of beetles in the family Hydrophilidae, the water scavenger beetles. This very large aquatic beetle is found in the Palearctic and is known by the common name great silver water beetle.
Hydrochara is a genus of hydrophilid beetles with 23 species in North America, Europe, Asia, and Africa.
Platycerus caprea is a species of beetle, from the subfamily Lucaninae of family Lucanidae. It was discovered by Charles De Geer in 1774, and was thus the first known member of its genus.
Sternolophus rufipes is a species of water scavenger beetle found in India, Sri Lanka, China, South Korea and the Philippines.
