Harmonia quadripunctata, the cream-streaked lady beetle or four-spot ladybird, is a species of ladybird belonging to the family Coccinellidae. Harmonia quadripunctata is a large Coccinellid with a length of 5.5–6 millimetres (0.22–0.24 in). The colouration is highly variable. The species is typically bright red, brown or yellow, although some individuals with greatly expanded dark patches appear almost completely black. The common name "cream-streaked" is in reference to the vertical pale lines present on many individuals. Although the base pattern consists of 18 black spots, many individuals do not show all 18 markings. The 2 marginal spots on each elytron frequently show even in the lightest marked individuals, hence the species epithet quadripunctata.
The pronotum is not very variable, with a consistent pattern of 11 markings, 5 of which are large and bold. The underside of H5 is dark with orange-brown sides, as in most Harmonia. Lighter specimens with limited spots may be similar to H. axyridis, but the pronotum and elytral pattern does not overlap.
The four-spot ladybird is a predator of various species of aphids such as Lachnus pinicola. The period of activity... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cream-Streaked Ladybird is recorded against all the insects logged in Porto (19 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.
