American Burying Beetle
North America’s largest carrion beetle converts one small vertebrate carcass into an underground brood chamber, then does something exceptional for an insect: both parents tend and feed the larvae.

American Burying Beetles are large glossy-black insects with two scalloped orange-red marks on each wing cover, orange-tipped antennal clubs, and an orange-red patch on the raised pronotum. That pronotal patch is the decisive feature shared by no other North American Nicrophorus.
On warm nights a pair may locate carrion from miles away, defeat competitors, bury the carcass, strip fur or feathers, and coat it with secretions that slow microbes. Larvae beg and receive regurgitated food. Because the species is federally threatened, this behavior belongs in authorized research and conservation programs—not a baited personal search.
- Federal status
- Threatened since the 2020 reclassification
- Diagnostic mark
- Large orange-red patch centered on the pronotum
- Family behavior
- A buried carcass prepared and guarded with parental feeding
Quick guide
- Confirm only an incidental view
- Use body size, pronotal patch, wing-cover marks, and orange antennal clubs
- Protect the record
- Photograph without handling and report through wildlife authorities
Recognize an American Burying Beetle without creating a carcass trap
- Begin with the pronotum
- Look for the large orange-red patch centered on the raised shield behind the head. Compare it with the scalloped orange-red wing-cover marks and orange-tipped antennal clubs.
- Record scale and context
- Photograph the beetle beside a noncontact scale reference and note Missouri county, date, time, temperature, habitat, and whether carrion was already present. Avoid publishing a precise sensitive location.
- Leave the breeding resource intact
- Never lift, roll, rebury, or remove a carcass and never dig beneath it. Watch only from legal durable ground because the brood chamber and eggs may be invisible below.
- Route the observation correctly
- Report a credible incidental American Burying Beetle record promptly to Missouri or federal wildlife authorities. Do not bait, trap, mark, handle, or retain the federally threatened beetle without permits.
Good to know
Read the carcass as a nursery rather than refuse: parents shape and preserve it, larvae beg for regurgitated food, and at least one adult usually remains through early development.
