Staphylinoidea
Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution. Description Adult staphylinoids are generally small beetles no more than a few millimetres long, though Staphylinidae can reach 50 mm long and Silphidae can reach 45 mm. The superfamily includes the smallest beetles (and the smallest of all non-parasitic insects) in family Ptiliidae. Most Ptiliidae do not exceed 1 mm long as adults, while the smallest species is just 325 µm long. Adults can be recognised by the hind wings having no accessory posterior ridge (locking device), no medial loop, no wedge cell and no apical hinge. The 8th segment of the abdomen is not entirely invaginated within the 7th. The head usually lacks a coronal suture (rarely with a short, rudimentary suture). Larval staphylinoids have 3-segmented (rarely 4-segmented) maxillary palps with distinct (often fused) galia and lacinia. The body usually has well-developed tergites and sternites. The spi ...

Jacobsoniidae
Jacobsoniidae are a family of tiny beetles belonging to Staphylinoidea. The larvae and adults live under bark, in plant litter, fungi, bat guano and rotten wood. There are around 28 described species in three genera: Description Members of this family have a small body size (0.7-2.1mm in length). Their bodies are narrow, and are four times as long as they are wide. They are often a yellowish-brown in color. Ecology Members of the group have primarily been found in leaf litter or in rotting wood, but some has have also been found in fungal fruting bodies or bat guano. The biology of members of this group is essentially unknown. Taxonomy Their taxonomic position has long been controversial, originally they were placed in Dermestoidea, before being considered Polyphaga ''incertae sedis.'' They were later placed in the Staphylinoidea, which is supported by characters of the wing venation as well as the morphology of the larval galea of the maxillae. Distribution Members of thi ...

Hydraenidae
Hydraenidae is a family of very small aquatic beetles, sometimes called "Minute moss beetles", with a worldwide distribution. They are around 0.8 to 3.3 mm in length. The adults store air on the underside of the body as well as beneath the elytra which allows them to crawl underwater, often on the underside of the water surface tension, though they cannot swim. Some species have gills that effectively allow them to stay underwater indefinitely. Larvae vary from being fully terrestrial, to being aquatic at least in their earliest instars. The diet of hydraenid larvae and adults is thought to consist of algae, spores and other plant matter. At least some hydraenid adults use stridulation to communicate. There are around 1,300 species in 42 genera.Jäch, Manfred A., Beutel, Rolf G., Delgado, Juan A. and Díaz, Juan A.. "Hydraenidae Mulsant, 1844: Coleoptera, Beetles".

Agyrtidae
Agyrtidae, or primitive carrion beetles, are a small family of beetles belonging to Staphylinoidea. They are found in mostly temperate areas of the Northern Hemisphere and in New Zealand. Characteristics Agyrtidae are small or middle-sized beetles (length 4–14 mm). They have usually oval body, but the Pterolomatinae are superficially similar to ground beetles. Abdomen is with five visible ventral sclerites, procoxal cavities internally open. Hindwings have anal lobe but no radial hinge. Ecology The group have a diverse ecological habits, but appear to be mostly saprophagous. Necrophilinae is attracted to decaying material including carrion, rotting fungi and dung, in the vicinity of temperate forests. Agyrtinae have a diverse variety of habits, with the genus '' Lyrosoma'' being found on cold beaches of the North Pacific rim, where they have been found feeding on kelp and dead seabirds, while '' Ipelates'' is associated with decaying logs and fungi, leaf litter, veg ...

Silphidae
Silphidae is a family of beetles that are known commonly as large carrion beetles, carrion beetles or burying beetles. There are two subfamilies: Silphinae and Nicrophorinae. Nicrophorines are sometimes known as sexton beetles. The number of species is relatively small at around two hundred. They are more diverse in the temperate region although a few tropical endemics are known. Both subfamilies feed on decaying organic matter such as dead animals. The subfamilies differ in which uses parental care and which types of carcasses they prefer. Silphidae are considered to be of importance to forensic entomologists because when they are found on a decaying body they are used to help estimate a post-mortem interval. Taxonomy, evolution, and etymology The family Silphidae belongs to the order Coleoptera. They are commonly referred to as carrion beetles or burying beetles and are usually associated with carrion, fungi, and dung. In the past, members of the family Agyrtidae were ...

Ptiliidae
Ptiliidae is a family of very tiny beetles with a cosmopolitan distribution. This family contains the smallest of all beetles, with a length when fully grown of . The weight is approximately 0.4 milligrams. They are colloquially called featherwing beetles, because the hindwings are narrow and feathery. Ptillid wings are feathery due to the much higher effective viscosity of air at small body sizes, which makes normal insect wings much less efficient. Unlike other small insects with feathery wings, such as parasitic wasps like fairyflies, ptillids do not fly using a clap and fling motion, but instead fly using a figure of eight pattern where the wings clap at the apex of the upward and downward strokes. They are capable of flying at speeds comparable to their larger relatives. The small size has forced many species to sacrifice some of their anatomy, like the heart, crop, and gizzard. While the exoskeleton and respiration system of the insects seems to be the major limitin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leiodidae
Leiodidae is a family of beetles with around 3800 described species found worldwide. Members of this family are commonly called round fungus beetles due to the globular shape of many species, although some are more elongated in shape. They are generally small or very small beetles (less than 10 mm in length) and many (but not all) species have clubbed antennae. Members of the family are generally saprophagous or scavengers feeding on carrion or decaying organic matter like dung, or are specialised on feeding on specific types of fungus. Many species have reduced wings, with about half of all described species being flightless. The oldest fossil of the family is '' Mesagyrtoides'' from Shar-Teg, Mongolia, dating the Late Jurassic ( Tithonian). Members of modern subfamilies appear during the Cretaceous, with Cretaceous members of the family being primarily known from Burmese amber.
