Asphondylia photiniae
In 3 days ~10%
Asphondylia photiniae, also known as the toyon fruit gall midge or toyon berry gall midge, is a species of midge that induces galls on the developing berries of the toyon bush in North America. Galled berries stay green (when other fruit has ripened to red or gold, etc.) and look somewhat warped. Each galled berry contains a single larva, which emerges in spring. This midge is known from the Californias, where native Heteromeles arbutifolia grows in relative abundance. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Toyon Fruit Gall Midge is recorded against all the insects logged in Los Angeles (9 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.
