Micraspis discolor is a species of ladybird. It was described by Johan Christian Fabricius in 1798. It is widespread throughout Asia, North America and parts of Oceania. It is found in Bangladesh, China, India, Malaysia, Sri Lanka, Taiwan, Vietnam, United States, Hawaii and Tonga.
Body length is 5 to 6 mm. Adult has a reddish orange body which is oval in shape. There are black stripes on elytra. It is one of the most common lady beetle found in rice ecosystems particularly during flowering and feeds on pollen. The species can be used as a bio-control agent for brown planthopper. It is found as both entomophagous and phytophagous species of beetle.
Both adult beetles and nymphs are voracious predators on several pests such as, Aphis craccivora, Aphis gossypii, Aphis spiraecola, Leptocorisa acuta, Myzus persicae, Nephotettix cincticeps, Opisina arenosella, Pentalonia nigronervosa and Sogatella furcifera. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Discolored Lady Beetle is recorded against all the insects logged in Kolkata (8 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.
