Amphibolips quercuspomiformis
In 3 days ~10% in a week ~30%
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 →

Rare
Under 5% of wildlife watchers report a Live Oak Apple Gall Wasp sighting in Los Angeles on a given day, based on 259 verified sightings from GBIF citizen-science data. It is the 114th most-seen of the 851 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January–February and October
In those months about 10% of wildlife watchers report a Live Oak Apple Gall Wasp in Los Angeles on a given day, against under 5% in March–September and November–December, the lowest months. Those are among Los Angeles's wettest months, with about 55 mm of rain a month against almost none in June.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Live Oak Apple Gall Wasp sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Live Oak Apple Gall Wasp sightings, Los Angeles ranks 3rd at under 5%. The best odds are in Sacramento (United States, about 10%) and San Francisco (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Live Oak Apple Gall Wasp is recorded against all the insects logged in Los Angeles (259 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.
