In the western states, where most recent research has been done, the species is found in diverse habitats--grasslands, tallgrass prairie, pastures, old field shrubland, deciduous (oak-hickory), and coniferous (pine) forests--all habitats in which the requisite soil conditions seem likely. Is rescue from outside populations likely? This paper summarized exhaustively the work on the species to that year. Box 6000, Fredericton, New Brunswick, Canada, E3B 5H1. However, continued occurrence even in this area now seems very unlikely based on a recent directed search (see below under Search effort). Direct predation seems likely to have played a part, given the increase in appropriate predators over the species’ range, but is not thought to be the major cause of the decline either of the species or its supply of brood carcasses. Darimont, b K.S. 250 g, the greater the brood fecundity. NatureServe Explorer. Paul Michael Brunelle has been studying the Odonata of Atlantic Canada and northern New England since 1987. Globally, the American Burying Beetle is listed in the IUCN Red List as Critically Endangered, subrank A1c, based on a population reduction of ≥90% and a decline in area of occupancy and occurrence (IUCN 2009). Dr. Lynn Gillespie, Research Scientist, Canadian Museum of Nature, P.O. CW69-14/640-2012E-PDFISBN 978-1-100-20213-6. 1982. Davis, L., Jr. 1980. There are a number of hypotheses, many of which are unconvincing due to the apparent lack of impact on congeners of similar behaviour and requirements. 1995. comm., 2003). It belongs to the carrion beetle family (Silphidae), and the genus Nicrophorus (sexton or burying beetles). August 6 1951, collector: E.J. Anderson (1982) believed that the clearing of primary forests in eastern North America was responsible for the species’ extirpation there; however, its extant western populations are in areas where there is considerable agricultural development, though some forest remains in uplands. Thus the loss of anthropogenic middens seems unlikely to have been significant. Relationship between numbers of the endangered American burying beetle Nicrophorus americanus Olivier (Coleoptera: Silphidae) and available food resources. They are crepuscular and nocturnal, and generally active from April through September. Fish and Wildlife Service. Beck, D. Lepage and A.R. Holloway, A.K., and G.D. Schnell. Anderson (1982) attributed the decline of the American Burying Beetle to “the destruction of primary forests in the eastern United States and Canada”. TULSA, Okla.— The U.S. Christie, b T.E. The development of dense understory in cleared forest areas increases the difficulty of burying the brood carcass, and hence the vulnerability of the beetle pair to predation… Dr. Robert F. Foster, 363 Van Horne Street, Thunder Bay, Ontario, Canada, P7A 3G3. 2009. Congeners do not likely compete with the American Burying Beetle, as its larger size ensures dominance at potential brood carcasses (Raithel 1991). Raithel. This survey utilized optimum and recently developed sampling procedures. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. There was a massive increase in vehicle travel in the 1900s, and that increase was likely proportionately crepuscular and nocturnal. The larvae may also be vulnerable to parasitic wasps, as are many larval insects, if the adult beetles cannot drive them off. 1989. Box 37012, Washington, DC, United States, 20013-7012, University of Guelph (UG). The Coleopterists Bulletin 36(2): 362-365. The Coyote(Canis latrans) is presumably a particularly significant predator on the species, and a competitor for the beetle’s brood carcasses, and its range has expanded into eastern North America during the timeframe of the apparent extirpation of the beetle from many areas (Pederson 2004). All reports are in heavily impacted agricultural or urbanized areas, although that might conceivably not have been the case on the dates of encounter. Since the species was federally listed in the United States in 1989, there have been considerable efforts devoted to finding it, with some success in the Midwest, and some clear indications of its extirpation elsewhere. The decline is believed to have begun in the 1920s. 2010. 2008 IUCN Red List of Threatened Species. Globally, the American Burying Beetle is listed in the IUCN Red List as Critically Endangered, based on a population reduction of ≥90% and a decline in area of occupancy and occurrence. 1996. All reports are somewhat vague with respect to location (usually only a town or city is mentioned) and lack habitat descriptions. Loss of suitable carrion has very likely been a factor in decline. 19 pp. The vast majority of related species do not practice this trait. The breaking up of suitable habitat into small areas separated by unsuitable conditions is termed habitat fragmentation. Wayne National Forest, Nelsonville, Ohio. The pair, on their backs, lift the carcass from below with their legs to assess its weight. It seems unlikely that any one factor is responsible for the species’ decline. There appear to be three requirements for viable habitat (Sikes and Raithel 2002): (1) soils sufficiently friable for the excavation of the brood chamber (see Life cycle); (2) presence of a sufficient supply of carcasses of the appropriate size; and (3) absence of an overwhelming number of competitors for the carcasses. The species was listed as an Endangered Species federally in the United States through the U.S. Fragmentation increases the need for species’ movement across unsuitable habitats and over roads. * Formerly described as “Vulnerable” from 1990 to 1999, or “Rare” prior to 1990. It must compete for the carcasses with other carrion-using insects such as flies. The report for Nova Scotia is generally considered to have originated in an error in Madge (1956), although it persists in some data holdings. Are there extreme fluctuations in number of locations? COSEWIC comprises representatives from each provincial and territorial government wildlife agency, four federal agencies (Canadian Wildlife Service, Parks Canada Agency, Department of Fisheries and Oceans, and the Federal Biosystematic Partnership), three nonjurisdictional members and the co-chairs of the species specialist groups. The species is sympatric with its congeners Nicrophorus marginatus, N. tomentosus, and N. orbicollis (and possibly others such as N. defodiens, N. pustulatus, N. sayi, and N. vespilloides), but readily discriminated by its larger size and the orange marking on the pronotum. Their antennae are pronouncedly club-like.

One population is on Block Island, Rhode Island. For enquiries, contact us. Anthropogenic middens, where pest carcasses such as rats are discarded at ground level or a bit above, may have supported the species until the practice of having personal garbage piles was discontinued, particularly in urban areas. Single males attract mates by releasing a pheromonefrom the tip of their abdomens. It is probable that the availability of vertebrate carcasses of the appropriate size in a particular area is more important than vegetation cover or soil composition (Raithel 1991). 1985. Raithel (1991) pointed out that the reduction of carcass resources as the primary mechanism of decline is based on circumstantial evidence, although the timeframe of the decline is suggestive. The development of dense understory in cleared forest areas increases the difficulty of burying the brood carcass, and hence the vulnerability of the beetle pair to predation. American Burying Beetles must compete with other invertebrate species, as well as vertebrate species, for carrion (see Predation above). No other locale, no date, collector unknown, one adult, deposited at the Lyman Entomology Museum. comm., 2003). This might be because burying beetles reproduce on small vertebrate carcasses that they bury in the soil as a food resource for their developing larvae, which pupate and enclose in the soil. It has been speculated that the extinction of Passenger Pigeons (Ectopistes migratorius (Linnaeus 1766)) around 1900 may have contributed to the decline of N. americanus, because these birds were in the ideal weight range for the species (Sikes and Raithel 2002). The carcass then may be moved as far as a metre until soil suitable for excavation is reached, then buried before the dawn. SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. 2010. Source: P.M. Brunelle, after Raithel (1991) and Lomolino et al. The species offers a rich resource for behavioural study, particularly as it is a member of one of the few insect groups that exhibit parental behaviour. Alan Dextrase, Senior Species at Risk Biologist, Species at Risk Section, Fish and Wildlife Branch, Natural Resource Management Division, Ontario Ministry of Natural Resources, P.O. Field and laboratory studies have indicated that the biology of N. americanus is similar to that of congeners except with respect to the optimal size range of carcasses used in reproduction. Reason for designation There is sufficient information to document that no individuals of the wildlife species remain alive in Canada. The species requires well-drained humic or loamy soils without impediments to digging in order to quickly excavate the brood chamber in which to lay its eggs. This has likely contributed to the success of the American Burying Beetle on the island (Raithel 1991). The Carrion Beetles of Canada and Alaska, Coleoptera: Silphidae and Agyrtidae. Reintroduction is currently being attempted on Nantucket and Penikese islands in Massachusetts, and captive breeding programs are being conducted at Boston University, the Cincinnati Zoo, and in Oklahoma.

A heavily urbanized area today.No date, collector unknown, one adult, deposited at ‘CMNH’ (Canadian Museum of Nature) but according to François Génier (CMN) there is no specimen in CMN coming from Montréal nor elsewhere in the province of Québec. July 1913, collector: J.-I. The species requires well-drained humic or loamy soils without impediments to digging in order to quickly excavate the brood chamber in which to lay its eggs. The species feeds primarily on the carcasses of vertebrates, particularly mammals and birds, but are also opportunistic scavengers in that they will evidently feed on any dead animal. Angela McConnell, Environment Canada, 4905 Dufferin Street, Downsview, Ontario, Canada, M3H 5T4. 2007. Although some birds have increased in southern Ontario over the last two decades (bird atlas results--Cadman et al. Holloway and Schnell (1997) stated that “American burying beetles frequented sites where small vertebrates (particularly mammals) were relatively abundant, irrespective of the predominant habitat at that site”. The North American population of Passenger Pigeons was at one time 3 to 5 billion, with a density of 5 to 6 birds per acre. One mechanism that increases the difficulty of burying is the growth of a heavy understory of bush and small trees, which increases the roots which must be cleared-- this increase comes about from the clearing of mature forests. Burying beetles are unusual among insects in that both the male […] The American burying beetle, Nicrophorus americanus: studies on the natural history of a declining species. The adults again emerge in the spring to feed and begin their evening search for a recently deceased suitable brood carcass. Often both parents remain with the larvae until they pupate, but sometimes only the female stays. In May and June of last year, five American burying beetles fell into similar carrion traps that their great-grandparents, or perhaps even more distant descendants, had stumbled upon in the Nebraska prairie. Raymond Hutchinson kindly reviewed this document. American Burying Beetle (Nicrophorus americanus) Recovery Plan. Source: P.M. Brunelle, after Raithel (1991) and Lomolino et al. Individuals will typically have the opportunity to reproduce only once; however, they may occasionally succeed in raising two broods in a season, particularly in the warmer and longer spring and summer at the centre of the continent. The other is a recently discovered population in eastern Oklahoma. The species has not yet been assessed under the National General Status protocols for Canada (Wild Species 2009). Although it was discovered in four additional states in the United States after listing in 1989, these areas were not on temperature-related range limits as was its northern limit in Canada. It is also of interest and under study with regard to the production of beneficial substances that eliminate bacteria and fungi. 93(3): 589-594. The species, having been recognized as having suffered an extraordinary and presumably anthropogenic decline, offers the potential for enlightenment regarding human impacts on invertebrate species, and other ecological subjects. Sean Blaney, Botanist and Assistant Director, PO Box 6416, Sackville, New Brunswick, Canada, E4L 1G6. There has been some consideration of infection by naturally occurring or introduced pathogens, specific to N. americanus, but none are known to be specific to the species, and congeners appear unaffected (Raithel 1991). Accessed February 2009, Range of Occurrence in Canada: southern Ontario, southern Quebec, Generation time (average age of parents in the population). Jurzenski and Hoback (2011) describe findings that Lithobates pipiens feeds on N. americanus. Ministere des Ressources naturelles et de la Faune du Québec – Fauna. Subnational distribution and conservation ranks east of the Red and Mississippi rivers. However, Walker and Hoback (2007) hypothesize based on a mark-recapture study that the advent of dense woody vegetation (Juniperus virginiana) in open habitat impacts N. americanus by limiting its “ability to forage for carrion.”. Adults begin their seasonal activities when the temperature exceeds 15°C. This habitat includes large mowed and grazed fields, and dense shrub thickets (ArkansasHabitat 2009). It is unlikely that such a large, heavy species would be involuntarily blown significant distances by heavy winds, and its behaviour does not suggest susceptibility to that mechanism for dispersion. Most Canadian reports are from the Mixedwood Plains Ecozone (basically the “Eastern deciduous forest region”), except for that from Port Sydney, Ontario, which is in the Boreal Shield Ecozone, though only about 50 km from its border with the Mixedwood Plains (NSWG 1996). Ann. No date, collector: H. Hudson, one adult, deposited at Harrow (‘Con?RepAg, Harrow, Ont.’). Colin Jones, Natural Heritage Project Zoologist, Natural Heritage Information Centre, Biodiversity Section. Peck. American Burying Beetle Distribution, Habitat, and Ecology Having evolved as native to North America, the amazing American Burying Beetle once inhabited a vast territory. After finding a carcass (most usually that of a small bird or a mouse), beetles fight amongst themselves (males fighting males, females fighting females) until the winning pair (usually the largest) remains. Draft 2 Title: Habitat use of co-occurring burying beetles (genus Nicrophorus) in southeastern Ontario Authors: Kevin W. Burke, Jillian D. Wettlaufer, David V. Beresford, Paul R. Martin Abstract: The coexistence of closely related species plays an important role in shaping local diversity. The historical north to south range is about 2,100 km (about 19°), from upper Michigan (about -46.5°N) to southern Texas (about -27.5°N). The extent of competition, however, remains unclear (Anderson 1982). Production note:COSEWIC would like to acknowledge Alana Taylor for writing the status report on the American Burying Beetle Nicrophorus americanus in Canada, prepared under contract with Environment Canada. COSEWIC status reports are working documents used in assigning the status of wildlife species suspected of being at risk.

However, it does range more widely than its smaller congeners (i.e., species of the same genus), and likely across more habitat types. Traps were also set at Harrow Agriculture and Agri-Food Canada Research Station, where the beetle was last seen in 1972.

August 1 1934, collector unknown, one adult, deposited at Harrow (‘Con?RepAg, Harrow, Ont.’). and would very likely have led to the discovery of N. americanus if it was present yet there was only one record over this period and that was 39 years ago. Comments on the current land use at the locales are based on viewing of air photos in Google Earth. A heavily urbanized area today, surrounded by heavy agricultural land use. Various areas where the species is reported in the United States are protected, though none are proximal to Canada. On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. Species designated at meetings of the full committee are added to the list. Ontario Ministry of Natural Resources (OMNR). Status history Designated Extirpated in November 2011. Fish and Wildlife Service has announced the downlisting of the American burying beetle from endangered to threatened despite the absence of the beetle from most of its range, ongoing habitat destruction from the oil and gas industry, and new information that climate change is decimating the species in the southern Plains. Source: P.M. Brunelle, after Raithel (1991) and Lomolino, Figure 2B. In literature, the species is likely to be confused with another valid carrion beetle species Necrophilia americana (Linnaeus 1758), the American Carrion Beetle, a flattened black species with a white-edged thorax.

Committee on the Status of Endangered Wildlife in Canada. Historical range of the American Burying Beetle. Nicrophorus americanus. Elsewhere, the fragmentation of habitat and increase in edge habitats such as hedges in developed areas likely increased the populations of these predators to the point where they have reduced American Burying Beetle adult populations. Vertebrate carcasses of any sort are used; however, bird chicks and rodents are probably most often employed. 80 pp. Burying beetles (Silpha vespillo) belong to the Silphidae family. At night, American burying beetles are active from late spring through early fall, occupy a variety of habitats and bury themselves in the soil to hibernate for the duration of the winter.
