Attagenus pellio
In 3 days ~10% in a week ~20%
Attagenus pellio, the fur beetle or carpet beetle, is a pest which damages stored products such as furs, skins, textiles and grain. It is a 4–6 mm-long oval shaped insect with two patches of white hair on the elytra. Their larvae, sometimes known as 'woolly bears' are honey-coloured and around ¼ inch long. The eggs are often laid in birds' nests, especially those of sparrows under the eaves. Thus they can invade homes where they live in floorboard cracks where wool or organic matter gathers. Nests of mice can also act as homes and food for the beetles. Wikipedia →

Under 5% of wildlife watchers report a Two-Spotted Carpet-Beetle sighting in Helsinki on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 602nd most-seen of the 838 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 March–April
In those months about 10% of wildlife watchers report a Two-Spotted Carpet-Beetle in Helsinki on a given day, against under 5% in February and May–December, the lowest months.

GBIF citizen-science records
It is estimated from how often the Two-Spotted Carpet-Beetle is recorded against all the insects logged in Helsinki (7 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.
