Junonia grisea, also known as the gray buckeye, grey buckeye, or Western buckeye, is a species in the butterfly family Nymphalidae. It is found in North America, west of the Rocky Mountains. Like the common buckeye, the gray buckeye is a brown butterfly with eyespots on its wings that distract predators from its body.
Junonia grisea was formerly considered a subspecies of the common buckeye, Junonia coenia, called Junonia coenia grisea. The gray buckeye's status as a separate species was discovered in 2018 by Dr. Jeffrey Marcus, an entomologist at the University of Manitoba, and Melanie Lalonde, a graduate student. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray Buckeye is recorded against all the insects logged in Los Angeles (745 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.
