Teuchestes fossor is a species of dung beetle native to the Palaearctic, but is also widespread in North America following accidental introduction and naturalisation during European settlement. Both adults and larvae are coprophagous, differentiating resource use by respectively feeding on the liquid and fibrous fractions of herbivore dung. It can be readily collected from the dung of livestock, and other large mammals This species is known to support a number of key ecosystem services in cattle pastures.
Teuchestes fossor was formerly a member of the genus Aphodius. Teuchestes fossor is a highly convex beetle measuring between 8–12 millimetres (0.31–0.47 in) in length, and 2–3 millimetres (0.079–0.118 in) in breadth. The scutellum is long, and reaches more than 20% sutural length. The elytral striae are relatively narrow. The pronotum is densely punctured towards side and front angles. Its typical colour is a uniform glossy black, although it can also rarely occurs in a dark red form where it may superficially resemble Acrossus rufipes. Males are differentiated from females by a small but prominent horn on the head.
Larvae are typical C-shaped... Wikipedia →

Rare
Under 5% of wildlife watchers report a Gravedigger Dung Beetle sighting in Pyrénées National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1026th most-seen of the 1277 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.
January and September–October
In those months about 10% of wildlife watchers report a Gravedigger Dung Beetle in Pyrénées National Park on a given day, against under 5% in February–August and November–December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Gravedigger Dung Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Gravedigger Dung Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Scarabaeidae
The closest relatives of the Gravedigger Dung Beetle that you can see in Pyrénées National Park (family Scarabaeidae, Scarabs) are Eurasian Bee Beetle (about 10%), European Rose Chafer (about 10%) and Mediterranean Spotted Chafer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gravedigger Dung Beetle is recorded against all the insects logged in Pyrénées National Park (6 verified sightings from 2019 to 2026), 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.
