Hydrophilidae
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 (= Georyssidae), 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. With rare exceptions, the larvae are predatory while the adults may be herbivores or predators in addition to scavenging. Many species are able to produce sounds. Species of '' Hydrophilus'' are reported as pests in fish hatcheries. Other species are voracious consumers of mosquito larvae, and have potential as biological control agents. This beetle family contains 2,835 species in 169 genera. Geography Hydrophilid beetles are found worldwi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphaeridiinae
Sphaeridiinae is a subfamily of water scavenger beetles (insects in the family Hydrophilidae). Some species live in fresh water as both larvae and adults. Habitat Sphaeridiinae is a subfamily of Hydrophilidae that is considered mostly terrestrial compared to the other aquatic subfamilies in the larger overarching family of Hydrophilidae. There have been some instances of this subfamily living in riparian habitats or floating vegetation, however, this subfamily is not constrained to aquatic ecosystems. In general, Hydrophilidae species have larvae that are aquatic or terrestrial and the adults are mainly aquatic. In Sphaeridiinae's case, there has been a trend for it to colonize on solely moist terrestrial land, including places of decomposition. Reproductive behavior The larvae stages of this subfamily also develop in moist areas like dung, decomposing fungi and plant material and moist soil. The adults also came back to fresh manure to lay their eggs. In addition, Sphaeridii ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropisternus Lateralis
''Tropisternus lateralis'' is a species of Hydrophilidae, hydrophilid beetle that ranges across much of the Americas. Description Adult ''T. lateralis nimabatus'', the subspecies found in the eastern United States, are distinguished by having uniformly dark elytron, elytra and prothorax, pronotum with light-colored borders. Distribution The range of ''T. lateralis'' includes North America as far north as southern Canada, South America south to northern Chile and Argentina, the Caribbean, and the Galápagos Islands. ''T. lateralis humeralis'' has been accidentally introduced to Oahu. Behavior ''T. lateralis'' exhibits stridulation during stress, calling, and courtship. Eggs are deposited in cases under water, and larvae are fully aquatic. While adults are primarily aquatic, they breathe air and can fly. Adult ''T. lateralis'' avoid colonizing and laying egg cases in ponds that contain fish, which are potential predators of all life stages of the beetles. Subspecies There are ...

Hydrochidae
''Hydrochus'' is the only living genus of beetle in the family Hydrochidae, which belongs to the superfamily Hydrophiloidea, and was formerly treated as a subfamily of Hydrophilidae. ''Hydrochus'' includes about 180 species, which are found worldwide.Archangelsky, M., Beutel, R. and Komarek, A. 2016. Hydrophiloidea Latreille, 1802: Coleoptera, Beetles. In: Schmidt-Rhaesa, A. ed. ''Handbook of Zoology Online'' [online]. Berlin, Boston: De Gruyter. [Accessed 2022-10-02] The name "''Hydrochus''" has also been used for a fly genus in the family Dolichopodidae, but this is a junior subjective synonym of the genus ''Rhaphium''. They are found in slow moving streams or stagnant water bodies, where they are associated with dense vegetation. In adults air is stored in a bubble on the underside of the body, with the antennae used to transfer atmospheric air to the bubble. The larvae live at the bottom of water bodies, indicating that they can breathe underwater. The diet is only known for th ...

Spercheidae
''Spercheus'' is a genus of aquatic beetles which are placed in a family of their own, Spercheidae within the Hydrophiloidea. About 20 species are known from around the world except the Nearctic with the majority being from the Oriental and Afrotropical Realms. All life stages are found in shallow still water with rich vegetation, which in some species includes temporary saline pools. Adults and larvae live attached to pieces of vegetation or debris, and also walk on the underside of the water surface. Air is held in a bubble on the underside of the body. The larvae feed on grazed detritus as well as drifting algae, dead organisms, and other organic refuse. The adults live as filter feeders on floating debris like decaying plant material and other decomposing organic remains. The adult females build a silken-egg case which they attach to their mid-tibiae and held by the hind legs, carried below the abdomen. These beetles were formerly placed in the family Hydrophilidae but are di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). 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 (ladybirds or ...

Talbragar Fossil Site
The Talbragar fossil site is a paleontological site of Late Jurassic (Tithonian) age in the central west of New South Wales, Australia. It lies about north-east of the town of Gulgong, and north-west of Sydney. The site has been known for over a century during which it has been extensively excavated to the point of near exhaustion. It is now registered as a Crown Land Reserve for the preservation of fossils; access is by permit, and the collection of rocks and fossil specimens is prohibited. The reserve is listed on the (now defunct) Register of the National Estate. Fossils The fossil-bearing rocks are fine-grained siltstones and mudstones that are part of the Purlawaugh Formation. They occur mainly as loose blocks and weathered shales over an area of about , with a thickness of no more than . They are thought to be the remnants of sediments from a small freshwater lake, surrounded by forest, which existed about 160 million years ago when Australia was part of Gondwana ...

Georissidae
''Georissus'', also called minute mud-loving beetles, is the only genus in the beetle family Georissidae (or Georyssidae). They are tiny insects living in wet soil, often near water. They are found on every continent except Antarctica. Characteristics Georissidae are small beetles (length 1–2 mm). They have a broadly oval body whose outline is more or less interrupted between the pronotum and the elytra. The head and pronotum are granulate, the prosternum is rudimentary, without intercoxal processes. The anterior coxae and trochanters are fused. The basal ventrite is very large. Ecology Species are generally found within mud and sand at the periphery of rivers and streams, but also occur in tropical rainforest leaf litter. Species of ''Georissus'' are predators on invertebrates, and under laboratory conditions sometimes engage in cannibalism. Species within the genus are known for their habit of psammophory (actively covering their elytra with sand or mud) which ...
