Colasposoma viridicoeruleum is a species of beetle belonging to the family Chrysomelidae, described by Victor Motschulsky in 1860. It is known as a pest of sweet potatoes. The species was formerly known as Colasposoma auripenne until 2003, when C. auripenne was determined to be a synonym of C. viridicoeruleum. It is sometimes considered a southern subspecies of Colasposoma dauricum, using the name Colasposoma dauricum auripenne.
Colasposoma viridicoeruleum can reach a length of 4–5 millimetres (0.16–0.20 in). The body is metallic green, blue or dark violaceous. Head is closely punctured, with black antennae. Thorax is twice as broad as long, with rounded sides and a punctured surface. Elytra show more strong punctures in irregular rows.
This species can be found in India, Andaman Islands, Myanmar, Malayan Subregion (Malay Peninsula, Sumatra, Java, Borneo and all the Indonesian Archipelago), Amur River region and China. Global Names Index Universal Biological Indexer Wikipedia →

GBIF citizen-science records
It is estimated from how often the Colasposoma viridicoeruleum is recorded against all the insects logged in Taroko National Park (6 verified sightings from 2019 to 2026), 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.
