Summary
Necrophilus is a genus of primitive carrion beetles in the family Agyrtidae, comprising at least three described species that inhabit areas in North America, interacting with the environment primarily as scavengers of decomposing organic material.
Physical Characteristics
Members of the genus Necrophilus are characterized by their primitive morphology and are generally small, with flat bodies.
Identification Tips
Look for flat brown scavenger beetles, particularly Necrophilus hydrophiloides, which can be identified by its distinct flat shape and coloration.
Habitat
These beetles are typically found in terrestrial habitats, particularly in areas where dead organic matter is abundant, such as forests and fields.
Distribution
There are at least three species of Necrophilus in North America, with one species occurring in the eastern regions from southern Ontario to Florida and Missouri to Louisiana, and another in western regions from Alaska to California.
Diet
Necrophilus species are scavengers and primarily feed on decomposing organic matter.
Life Cycle
Details on the life cycle of Necrophilus species specifically are not elaborated in the provided information, but they generally undergo complete metamorphosis including egg, larval, pupal, and adult stages.
Reproduction
Reproductive behaviors are not detailed, but generally, scavenger beetles lay eggs in or near decaying matter.
Ecosystem Role
As scavengers, these beetles play an important role in ecosystems by assisting in the decomposition process and nutrient recycling.
Collecting Methods
- Hand collection on carrion
- Traps baited with decaying matter
Preservation Methods
- Pinning for display
- Ethanol preservation for study
Evolution
The genus Necrophilus belongs to the primitive group of carrion beetles within the family Agyrtidae, illustrating an evolutionary adaptation to a scavenging lifestyle.
