In 3 days ~10% in a week ~20%
Anotylus rugosus is a species of spiny-legged rove beetle in the family Staphylinidae. It is found in Africa, Australia, Europe and Northern Asia (excluding China), and North America. They are common in wetland marginal situations, such as among reed litter, at carrion, among debris under bark, or in mammal and bird nests. They also occur among foliage or under debris in salt marshes and have been found under decaying seaweed on the strandline. They fly in warm weather, usually in the afternoon or evening. Wikipedia →

Rare
Under 5% of wildlife watchers report an Anotylus rugosus sighting in Montreal on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 842nd most-seen of the 926 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 an Anotylus rugosus in Montreal on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Anotylus rugosus sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Montreal, in our data
Montreal is the only city on Wallace's Line with enough records to rate Anotylus rugosus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Staphylinidae
The closest relatives of the Anotylus rugosus that you can see in Montreal (family Staphylinidae, Rove Beetles) are Sad Carrion Beetle (about 10%) and American Carrion Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Anotylus rugosus is recorded against all the insects logged in Montreal (5 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.
