Vibidia duodecimguttata, commonly known as the twelve-spotted ladybird beetle, is a species of ladybird beetle belonging to the family Coccinellidae, subfamily Coccinellinae. This species is present in most of Europe, in the eastern Palearctic realm, and in the Near East.
Vibidia duodecimguttata can reach a length of about 4 millimetres (0.16 in). These beetles have an oval shaped body with quite long, light brown antennae. The elytra have a slightly wider side edge. Their entire body has a light brown basic colour on the upper and lower side, only the eyes are black. The elytra show 12 whitish spots, six on each elytron (hence the Latin word duodecimguttata, meaning twelve-spotted as if by drops). There is a whitish spot on both sides of the throat.
This species bears resemblance to Calvia decemguttata and Halyzia sedecimguttata. Adults can be encountered from April through September. This beetle is mycophagous, mainly feeding on the powdery mildew which infects certain trees (including oak, hazel and alder).
First, the chase is expressed in rapid movements, with the male pausing for a moment at least twice before... Wikipedia →

GBIF citizen-science records
It is estimated from how often the 12-Spot Ladybird is recorded against all the insects logged in Brussels (26 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.
