Cantao ocellatus is a species of shield bug in the family Scutelleridae found across Asia. Cantao ocellatus is reddish or ochre in overall colour it has dark legs and bluish black antennae. A dark bluish black stripe is present along the central line of the head. The pronotum sometimes has two black spots on the front margin and sometimes has eight spots. The scutellum has eight or six black spots of variable size but with yellowish borders. The lateral angle of the pronotum is elongated into a curved spine but this can be much reduced. A distinctive symbiotic bacterial genus Sodalis from phylum Gammaproteobacteria is found in its midgut. Maternal care of eggs and nymphs has been noted in this species. The female stands over and covers the eggs after they are laid but eggs on the edge that she cannot cover are often parasitized by wasps.
Cantao ocellatus has been reported from the Indian Subcontinent into Southeast Asia and Papua New Guinea. It has also been reported from Japan and Zaire. Cantao ocellatus suck sap from a wide range of plants including Macaranga, Camellia sasanqua, Kigelia, Mallotus, Bischofia javanica... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Ocellated Shield Bug is recorded against all the insects logged in Shanghai (11 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.
