Anthrenus sarnicus, the Guernsey carpet beetle, is a type of carpet beetle ('Sarnia' is the Latin name for Guernsey). It can be generally found in Great Britain. Its suborder is Polyphaga, the infraorder is Bostrichiformia, the superfamily is Bostrichoidea, and the family is Dermestidae. The carpet beetle is shaped like an oval and about the size of a pin.
Carpet beetles are known for eating away at carpets and rugs. Their diet consists of feathers, furs, insects, dead animals, processed human food, skins, cotton, silk, and wool. A variety of predators like ants and spiders will feed on carpet beetle larvae. No predators will exclusively eat carpet beetles and the larvae will hide in dark places to avoid them.
All carpet beetles will go through metamorphism during their lives. They will pass through the egg, larval, and pupal points to reach full maturity. This can take two months to many years. Female carpet beetles can lay over 100 eggs which can hatch after 10–44 days at temperatures between 15 °C (59 °F) and 32.5 °C (90.5 °F), ideally at 25 °C (77 °F). Four generations of carpet beetles can develop every year. It can... Wikipedia →

Rare
Under 5% of wildlife watchers report a Guernsey Carpet Beetle sighting in London on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1059th most-seen of the 1504 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 Guernsey Carpet Beetle in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Guernsey Carpet Beetle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Guernsey Carpet Beetle is recorded against all the insects logged in London (10 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.
