Calliphara nobilis (commonly known as the mangrove jewel bug, mangrove shield bug, or mangrove stink bug) is a species of jewel bug found in Asia. Like all species of jewel bugs, it is phytophagous, feeding on the leaves, fruit and seeds of its host plants. This insect is notable for its multiple defense mechanisms: it is highly mobile and swarms disperse with a loud buzz when disturbed; it is aposematically colored, which serves as a warning to any would-be predators that it is unpalatable; and it possesses a robust chemical defense mechanism: it can secrete an irritating and toxic fluid from a pair of metathoracic scent glands when threatened.
C. nobilis is one of 15 species within the genus Calliphara. The genus is part of the Scutelleridae (shield bug) family, which contains some 80 genera and 500 species worldwide. The scutellerids in turn are part of the larger Pentatomoidea superfamily, (which contains the shield bugs, giant shield bugs, burrower bugs, and stink bugs).
Time-divergence studies reveal that the scutellerids and other types of phytophagous insects first emerged in the Early Cretaceous (142.1–122.8 Ma), shortly after the emergence... Wikipedia →

With luck
About 10% of wildlife watchers report a Mangrove Jewel Bug sighting in Sepilok on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 79th most-seen of the 87 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Mangrove Jewel Bug is recorded against all the insects logged in Sepilok (5 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.
