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] |
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] |
Sphaeridium Impressum
''Sphaeridium'' is a genus of 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 40 ...s in the family Hydrophilidae, the water scavenger beetles. They occur in Europe, and some species have been introduced species, introduced to North America.Hanski, I. (1980)The three coexisting species of ''Sphaeridium'' (Coleoptera, Hydrophilidae).''Ann. Entomol. Fenn'' 46, 39-48. Description The adults are 4 to 7.5 millimeters long. They have short Antenna (biology), antennae with hairy clubs at the tips. These beetles live in cow dung. The adults feed on the dung and other organic matter, but the beetle larvae are predators of the maggots of the flies that breed in the dung, such as the Musca autumnalis, face fly (''Musca autumnalis''). Two or more ''Sphaeridium'' beetle species may coexist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
