Anthrenus (Anthrenus) scrophulariae, also known as the common carpet beetle or buffalo carpet beetle, is a species of beetle originally found in Europe, the Middle East and the Nearctic, which has now spread to most of the world. Adult beetles feed on pollen and nectar, but the larvae feed on animal fibres and can be damaging pests to carpets, fabrics and museum specimens.
The adult common carpet beetle varies from about 2.5 to 3.8 mm (0.10 to 0.15 in) in length. The antennae have eleven segments, three of which form a club, and the eyes are notched at the front. The head is black but is largely concealed under the prothorax, which is also black, liberally speckled with white scales apart from a band in the centre. The elytra (wing cases) are black with orange or reddish scales near the midline and variable but symmetric patches of white scales elsewhere. As the beetle gets older, the scales tend to get rubbed off so the beetle changes in appearance. The small white eggs are laid in batches of 30 to 60 and have projections which help them to adhere to carpet fibres. The larvae are brown and moult five times before pupating; the final instar larva is hairy and larger... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Carpet Beetle is recorded against all the insects logged in Budapest (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.
