Heterorhina elegans is a species of scarab beetle found in India and Sri Lanka that belongs to the flower chafer subfamily. While originally described in the genus Cetonia in 1781, it was placed in the newly-described genus Heterorhina in 1842, though the genus name was often subsequently misspelled as "Heterorrhina" (e.g.,).
Adult beetles are emerald green with some varieties blue, red (var. fulgidissima), indigo, or black (var. anthracina). The sides of the hind coxae are orange. The elytra are glazed, with no deep pits on the surface and only tiny spots arranged in lines. The prothorax has punctures only along the sides and the scutellum is without any punctures. The antennae, legs, suture margins, posterior of the elytra and the apical calli are black. The clypeus may have some punctures and is squarish with parallel sides. The front margin is straight and toothed in the middle, the tooth is minutely notched. The forehead has lobed ridges running longitudinally. On the underside the sternal process is narrow and blunt, slightly curved. The middle and hind tibia are fringed with hairs in both the male and female. The hind tibiae bear a tuft of hairs...

With luck
About 10% of wildlife watchers report a Heterorhina elegans sighting in Bengaluru on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 477 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.
May and June
In those months about 20% of wildlife watchers report a Heterorhina elegans in Bengaluru on a given day, against under 5% in January–April, September and November, the lowest months.
Among the best
Of the 4 cities where we can rate Heterorhina elegans sightings, Bengaluru ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%).
Same family: Scarabaeidae
The closest relatives of the Heterorhina elegans that you can see in Bengaluru (family Scarabaeidae, Scarabs) are Protaetia aurichalcea (about 10%), Coconut Rhinoceros Beetle (about 10%) and Clinteria klugi (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Heterorhina elegans is recorded against all the insects logged in Bengaluru (39 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.
