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 (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae). 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 ... [...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.

Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae.

Beetle
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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 helps ...

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 175 million years ago when Australia was part of Gondwana. ...

Epimetopidae
Epimetopidae is a family of semi-aquatic beetles belonging to the Hydrophiloidea. They are found in sand and gravel at the edges of streams, rivers and shallow freshwater ponds. These beetles are shorter than half a centimeter long and have a pronotum with a central projection forming a shelf above the head. On the underside of the abdomen only four sternites are visible. There are approximately 72 described species in three genera, '' Epimetopus'' which is restricted to the New World, mostly Neotropical, '' Eupotemus'' with two Afrotropical species and '' Eumetopus'' with some Oriental The Orient is a term for the East in relation to Europe, traditionally comprising anything belonging to the Eastern world. It is the antonym of ''Occident'', the Western World. In English, it is largely a metonym for, and coterminous with, the ... species. Females carry their eggcases on the underside of the abdomen.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...
