Nicrophorus tomentosus (gold-necked carrion beetle or tomentose burying beetle) is a species of burying beetle that was described by Friedrich Weber in 1801. The beetle belongs to the family Silphidae which are carrion beetles. The beetles have sensitive antennae that contain olfactory organs. Thus, the beetle can locate dead animals (carcass), and then as the name suggests, can bury them. However, unlike other burying beetles, N. tomentosus does not completely bury these brood carcasses. They instead dig a shallow hole under the carcass and cover it with leaf litter. Recognition of these beetles can be distinguished by its black color with orange markings on the wing covers (elytra).
The genus name, Nicrophorus, means “death carrier”; tomentosus means "covered in short hair", referring to the pronotum. There are several characteristics that differentiate Silphidae from other families. One characteristic is that N. tomentosus is about 11.2–19.0 millimeters in length. It also has a pair of striations on its fifth abdominal tergum. They also have a very large scutellum which can sometimes be as wide as its head. The segments of its antennae are all... Wikipedia →

Rare
Under 5% of wildlife watchers report a Tomentose Burying Beetle sighting in Toronto on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 427th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Tomentose Burying Beetle in Toronto on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Tomentose Burying Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 9 cities where we can rate Tomentose Burying Beetle sightings, Toronto ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%), Minneapolis [Saint Paul] (United States, under 5%) and Boston (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Tomentose Burying Beetle is recorded against all the insects logged in Toronto (39 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
