Nicrophorus americanus

Field Notes
Description:
The American burying beetle (Nicrophorus americanus Oliver) classified as ‘Critically
Endangered’ on the IUCN Red List of Threatened Species, is the largest of North America’s carrion beetles.
Habitat:
Its historical range covered 35 states in the eastern temperate areas of North America. Today there remain only scattered populations in just eight states.
Notes:
Nicrophorus species rear their young on small dead mammals, birds, and reptiles. American burying beetles show some of the highest levels of parental care known among insects and require larger and higher-quality carcasses for reproduction than other Nicrophorus beetles. This is a key component to their reproductive success. Reasons for this species’ decline may include habitat loss, fragmentation and alteration causing species composition change. High densities of mammalian scavengers may compete with these beetles for carrion and the extinction or drastic reduction of potential carrion species (e.g. passenger pigeons) probably increased this competition.
Since attaining endangered species status in 1989 the US Fish and Wildlife Service initiated a conservation strategy for this species. The recovery plan includes monitoring the existing populations, maintaining captive populations, conducting surveys for additional wild populations and implementing reintroduction efforts.
