Amphibolips quercuspomiformis
In 3 days ~30% in a week ~50%
Amphibolips quercuspomiformis, also known as the apple gall wasp or live oak apple gall wasp, is a species of gall wasp. It induces galls in coast live oak and interior live oak trees. Like many gall wasps, it has two alternating generations which induce differing galls: an all-female parthenogenic generation, and a bisexual generation. The galls formed by the unisexual generation in summer are spherical, up to 40 mm in diameter, and covered with short spines. They form on stems and are green or red when new, then turn brown. The galls formed by the bisexual generation in spring are small, shaped like toadstools, and occur on leaves. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Live Oak Apple Gall Wasp is recorded against all the insects logged in Sacramento (102 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.
