Hoplia callipyge is a species of scarab beetle in the family Scarabaeidae. It has been recorded in the Western United States, British Columbia in Canada, and Baja California in Mexico. Adults are about 5.75–10.5 mm (0.226–0.413 in) long, 3.4–5 mm (0.13–0.20 in) wide, oval, and brown. They are very similar visually to other Hoplia species, especially H. hirta and H. laticollis.
The beetles are active March through May and are noted for feeding on the petals of light-colored roses. However, they also feed on other flowers and the young leaves and fruit of certain plants. Larvae hatch from white eggs in soil and feed on roots and decaying plants. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Grapevine Hoplia is recorded against all the insects logged in San Diego (24 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.
