In 3 days ~10% in a week ~20%
The Aholibah underwing (Catocala aholibah) is a moth of the "owlet" family Erebidae, which has over 25,000 known members, and more than that yet undescribed. Like other moths of the underwing genus (Catocala), this species has dull gray and black speckled forewings which help it blend into its surroundings, and bright orange underwings that it reveals to startle predators.
The adults are mature during the early summer, and are found in western North America from British Columbia south to Arizona. An adult has a wingspan of up to 8 centimeters. The larva is a dark gray mottled caterpillar with thick pink-tinted legs and a jumping ability. The adults feed on nectar, sap, and rotting fruit, while the larvae prefer the foliage of several oak species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Aholibah Underwing Moth is recorded against all the insects logged in Sacramento (10 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.
