Euphoria inda, the bumble flower beetle, brown fruit chafer or Indian cetonia is a species of beetle in the family Scarabaeidae. It is found in North America. While in flight, adults of this species do not lift their elytra, creating a buzzing sound as the hindwings vibrate inside. The adult beetle is a pollinator and feeds on pollen, nectar, sap and damaged fruits. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bumble Flower Beetle is recorded against all the insects logged in Denver (149 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.
