Trichodes ornatus, commonly known as ornate checkered beetle, is a beetle species of checkered beetles belonging to the family Cleridae, subfamily Clerinae which can be found only in North America. Larvae live in bee nests of mostly Megachilidae family species and are parasitic. While in the nest they feed on the bees' larvae or pollen. When they mature into an adult they begin feeding on yarrow, milkweed, and other plants of yellow colouration. The species males are 5–11 millimetres (0.20–0.43 in) long while females are 7–15 millimetres (0.28–0.59 in).

GBIF citizen-science records
It is estimated from how often the Ornate Checkered Beetle is recorded against all the insects logged in Yosemite National Park (50 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.
