Asteromyia carbonifera
In 3 days ~10% in a week ~30%
Asteromyia carbonifera is a species of gall midges in the family Cecidomyiidae. It creates galls on Solidago plants. Females can lay up to 300 eggs at a time and often collect conidia of the fungus Botryosphaeria dothidea, which is deposited on the plant alongside the eggs. The larvae grow within the gall that the fungus creates, a form of mutualism. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Carbonifera Goldenrod Gall Midge is recorded against all the insects logged in Chicago (79 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.
