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 include ...

Nicrophorus Orbicollis
''Nicrophorus orbicollis'' is a nearctic burying beetle first described by Thomas Say in 1825. It is a member of the genus '' Nicrophorus'' or sexton beetles, comprising the most common beetles in the family Silphidae. This species is a decomposer feeding on carcasses of small dead animals. ''N. orbicollis'' can be used for scientific research both medically and forensically (if the beetle is present in the area). Morphology/taxonomy Adult ''Nicrophorus orbicollis'' is immediately recognized by its colorful orange markings on its elytra. The dorsal surface of the elytra is covered in long, fine setae, especially laterally, giving it a hairy appearance. The pronotum is spherical with wide lateral and basal margins. Its most distinctive feature from other Silphidae is its clubbed antennae with three orange apical segments and a black base. The posterior lobe of the metepimeron has a few brown hairs and the hind tibia is straight. The adult form is moderately sized at about lo ...

Oiceoptoma Noveboracense
''Oiceoptoma noveboracense'' is a member of the family Silphidae, or carrion beetles, which feed on decaying organic matter such as dead animals. Its common name is the margined carrion beetle, from the orange-red margins on the pronotum, which are helpful when identifying this species. The larva is typically light brown to red and also has vertical ridges on its thorax like the adult. This diurnal beetle can be found mainly in the spring into the fall, and it has a strong preference towards a deciduous forest habitat. The primary forensic importance of this beetle is its ability to use the succession of insect fauna to provide confirmation of postmortem intervals.Byrd, Jason and Castner, James. Forensic Entomology: The Utility of Arthropods in Legal Investigations. Florida: CRC Press, 2001. Taxonomy ''Oiceoptoma noveboracense's'' Latin specific name means "pertaining to New York" (Latin ''Novum Eboracum'' + ''-ensis''), referring to the original source of the type specimen ...

Nicrophorus Tomentosus
''Nicrophorus tomentosus'' (gold-necked carrion beetle or tomentose burying beetle) is a species of burying beetle that was described by Friedrich Weber in 1801. The beetle belongs to the family Silphidae which are carrion beetles. The beetles have sensitive antennae that contain olfactory organs. Thus, the beetle can locate dead animals (carcass), and then as the name suggests, can bury them. However, unlike other burying beetles, ''N. tomentosus'' does not completely bury these brood carcasses. They instead dig a shallow hole under the carcass and cover it with leaf litter. Recognition of these beetles can be distinguished by its black color with orange markings on the wing covers (elytra). Classification The genus name, '' Nicrophorus'', means “death carrier”; ' means "covered in short hair", referring to the pronotum. Description There are several characteristics that differentiate Silphidae from other families. One characteristic is that ''N. tomentosus'' is about 11.2 ...

Necrophila Americana
The American carrion beetle (''Necrophila americana'',Species Necrophila americana - American Carrion Beetle: http://bugguide.net/node/view/6744 formerly ''Silpha americana'') is a North American beetle of the family Silphidae. It lays its eggs in, and its larvae consume, raw flesh (particularly that of dead animals) and fungi. The larvae and adults also consume fly larvae and the larvae of other carrion beetles that compete for the same food sources as its larvae. Range The beetle lives in North America east of the Rocky Mountains, with its southern boundary from eastern Texas to Florida and the northern boundary from Minnesota to southeastern Canada including New Brunswick and Maine. Appearance Adults are 12 to 22 mm long. The pronotum is primarily a pale yellow with a black spot in the center. In the southern portion of the range, the elytra are entirely black while in the northern portion they have a yellow rear tip. The elytra are shorter than the body of the beetle, ...

Sexton Beetle
Burying beetles or sexton beetles, genus ''Nicrophorus'', are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care of the brood. They are carnivores. The genus name is sometimes spelled ''Necrophorus'' in older texts: this was an unjustified emendation by Carl Peter Thunberg (1789) of Fabricius's original name, and is not valid under the ICZN. The American burying beetle (''Nicrophorus americanus'') has been on the U.S. endangered species list since 1989. Reproduction Burying beetles have large club-like antennae equipped with chemoreceptors capable of detecting a dead animal from a long distance. After finding a carcass (most usually that of a small bird or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Forensic Entomologist
Forensic entomology is the scientific study of the colonization of a dead body by arthropods. This includes the study of insect types commonly associated with cadavers, their respective life cycles, their ecological presences in a given environment, as well as the changes in insect assemblage with the progression of decomposition. Insect succession patterns are identified based on the time a given species of insect spends in a given developmental stage, and how many generations have been produced since the insects introduction to a given food source. Insect development alongside environmental data such as temperature and vapor density, can be used to estimate the time since death, due to the fact that flying insects are attracted to a body immediately after death. The identification of postmortem interval to aid in death investigations is the primary scope of this scientific field. However, forensic entomology is not limited to homicides, it has also been used in cases of neglect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
