Gyrinus sericeolimbatus, is a species of whirligig beetle found in India, Sri Lanka, New Guinea, Philippines, Solomon Islands. [1] [2] [3] [4]
The whirligig beetles are water beetles, comprising the family Gyrinidae that usually swim on the surface of the water if undisturbed, though they swim underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. The family includes some 700 extant species worldwide, in 15 genera, plus a few fossil species. Most species are very similar in general appearance, though they vary in size from perhaps 3 mm to 18 mm in length. They tend to be flattened and rounded in cross section, in plain view as seen from above, and in longitudinal section. In fact their shape is a good first approximation to an ellipsoid, with legs and other appendages fitting closely into a streamlined surface. Whirligig beetles belong to the beetle suborder Adephaga, which also includes ground beetles and diving beetles.
Holometabola, also known as Endopterygota, is a superorder of insects within the infraclass Neoptera that go through distinctive larval, pupal, and adult stages. They undergo a radical metamorphosis, with the larval and adult stages differing considerably in their structure and behaviour. This is called holometabolism, or complete metamorphism.
The Adephaga are a suborder of beetles, and with more than 40,000 recorded species in 10 families, the second-largest of the four beetle suborders. Members of this suborder are collectively known as adephagans. The largest family is Carabidae which comprises most of the suborder with over 40,000 species. Adephaga also includes a variety of aquatic beetles, such as predaceous diving beetles and whirligig beetles.
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.
The superfamily Membracoidea of sap-sucking true-bugs includes two of the largest families within what used to be called the "Homoptera": the leafhoppers (Cicadellidae) and the treehoppers (Membracidae). The other families in this group are quite small, and have, at various points, generally been included as members within other families, though they are all presently considered to be valid, monophyletic groups. The relict family Myerslopiidae is restricted to New Zealand and South America while the Melizoderidae consist of two genera restricted to South America. The great diversity of Neotropical taxa suggests that the group originated in that region.
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae, but several of the subfamilies have been removed and raised to family rank. Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described species. The other families have no more than 400 species. The Histeroidea are closely related and sometimes considered part of a sensu lato Hydrophiloidea. The majority of the clade is aquatic, which is thought to be the ancestral ecology of the group, with some lineages like Sphaeridiinae becoming secondarily terrestrial. Modern representatives of the group first appeared during the Late Jurassic.
Helophorus ís the only genus in the beetle family Helophoridae within the Hydrophiloidea. They are small insects, found mainly in the Holarctic region, but two or three species also live in the Afrotropical region, Central America and one in the Indomalayan region.
Nicrophorus nepalensisHope,, commonly known as burying beetle, is widespread across tropical and subtropical countries in Asia. It belongs to the order Coleoptera and the family Silphidae, and is part of the nepalensis species-group, which is the second largest species group within the genus Nicrophorus. N. nepalensis differs from some other beetles in that it exhibits biparental care. Its role as a decomposer is crucial in the energy cycle and energy transformation in the ecosystem.
Acilius is a holarctic genus of diving beetles in the family Dytiscidae and typically has a life cycle that is univoltine.
Lamingtonium is the only genus in the family Lamingtoniidae, of the beetle superfamily Cucujoidea. It contains three species endemic to Australia. The holotype of the type species was collected on at Lamington National Park, Binna Burra, Queensland under the bark of a dead tree. The adults and larvae of two species have been found associated with basidiocarps of fungi belonging to the family Polyporaceae.
The Ibaliidae are a small family of the hymenopteran superfamily Cynipoidea. Ibaliidae differ from most of the cynipoids by the larvae being parasitoids on other wasp larvae in the group Siricidae. The Ibaliidae comprise three extant genera of fairly large wasps, with a total of 20 species, and is a sister group to the rest of the cynipoids except the small subfamily Austrocynipidae.
Enhydrus is a genus of beetles in the family Gyrinidae, containing the following species:
Acidocerinae is a subfamily in the family Hydrophilidae of aquatic beetles, and it contains over 500 species in 23 genera.
Marianne Horak is a Swiss-Australian entomologist who specialises in Australian Lepidoptera, particularly the phycitine and tortricid moths, and is considered one of the worldwide leading experts on the systematics of Tortricidae.
Gyrinus gehringi is a species of whirligig beetle in the family Gyrinidae. It is found in North America.
Gyrininae is a subfamily of ground and water beetles in the family Gyrinidae. There are at least 740 described extant species in Gyrininae.
Acalypta parvula is a species of lace bug in the family Tingidae. It is found in Africa, Europe and Northern Asia, and North America.
Gyrinus convexiusculus is a species of whirligig beetle in the family Gyrinidae, first described by Macleay in 1871.
Gyrinus gibbus is a species of aquatic beetle in the family Gyrinidae. It is native to the Neotropics.
Peltochares is a genus of water scavenger beetles in the family Hydrophilidae represented by eight described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, and Palaearctic realms.
