Poecilochirus
''Poecilochirus'' is a Holarctic genus of mites in the family Parasitidae. They are relatively large (ca. 0.5-1mm) and often found on rotting corpses, where they are transported by beetles. Deuteronymphs are characterized by two orange dorsal shields and in many species a transverse band on the sternal shield. The juvenile development consists of a larval stage (three pairs of legs), protonymph, and deuteronymph, but no tritonymph. Females are smaller than males. Males guard female deuteronymphs shortly before these mate, and pairs mate venter-to-venter. Reportedly, some nematodes in the family Allantonematidae are parasites of mites in this genus. Although some species from this genus have been described and sampled on previous real forensic cases or successional studies on carcasses, their usefulness as a forensic marker in forensic entomology has been recently appreciated.

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 ...

Parasitidae
Parasitidae is a family of predatory mites in the order Mesostigmata that has worldwide distribution. They are the only family in the superfamily Parasitoidea. Relatively large for mites, their color is often yellowish to dark brown. The family as a whole preys on a wide variety of microarthropods and nematodes, with individual species usually having a narrower range of prey. The family contains two subfamilies, 29 genera, and around 400 species. The subfamily Pergamasinae is normally found in the soil, and dispersal via phoresy is not known in this subfamily. It contains 9 genera. Most species are bisexual. The subfamily Parasitinae is normally found in nests of small animals or insects or in decaying organic matter, from seaweed to forest litter. This subfamily contains 20 genera. These mites disperse via phoresy in the deuteronymph stage of their life cycle. The genus '' Parasitellus'' is associated with bumblebees, and other genus with other bees, leading to the common nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicrophorus Vespilloides
''Nicrophorus vespilloides'' is a burying beetle described by Johann Friedrich Wilhelm Herbst in 1783. The beetles are 10 – 18 mm long. They have two conspicuous orange-yellow bands on the elytra. The color of the antennae are an important distinguishing feature, being totally black. This is one of the most well studied of the burying beetles with over 1,000 citations found via Google Scholar. What had been considered ''Nicrophorus vespilloides'' in mid and eastern Canada and northeastern USA was determined by Sikes et al. in 2016 to be a separate, overlooked sister species of ''Nicrophorus vespilloides'' that had been named by Kirby in 1837. This sister species, ''Nicrophorus hebes'' Kirby, is restricted to ''Sphagnum'' bogs and marshes,. ''Nicrophorus vespilloides'' occurs throughout the northern Palearctic, Alaska and northwestern Canada where it is found in open forest habitats. The restriction of its sister species ''N. hebes'' to bogs in North America has been att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forensic Entomology
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] |
Nicrophorus Vespillo
''Nicrophorus vespillo'' is a burying beetle described by Carl Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalise ... in his landmark 1758 10th edition of ''Systema Naturae''. It has a paleartic distribution and is commonly found across Europe and Asia, extending from Western Europe to Mongolia. Description These are large beetles, from 12 to 25 mm in length and fly strongly. The beetles have two striking orange-yellow bands on the wing-cases. They are distinguished from others in the genus by the long golden hairs on the body and wing-cases as well as the orange club-shaped ends of the antennae and the shape of the hind legs. Reproduction They live on and lay eggs near carrion. The beetles reproduce from May to September, with both parents participating in preparations ...
