Cynips quercusfolii, also known as the cherry gall wasp and common oak gall wasp, is a gall wasp species in the genus Cynips and family Cynipidae. The species is important for the production of commercial nutgall formed on Quercus lusitanica (the gall oak).
Galls are located on the underside of leaves, with the majority of galls being on the second and third veins from the petiole of the leaf. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cherry Gall Wasp is recorded against all the insects logged in Kharkiv (138 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.
