In 3 days ~10% in a week ~20%
Stigmella intermedia is a moth of the family Nepticulidae. It is found in North America in Ohio, Arkansas, Kentucky and Ontario. The wingspan is 3-3.5 mm. Usually there are two generations per year, with larvae maturing in July and overwintering, but occasionally a third generation appears.
The larvae feed on Rhus typhina and Rhus aromatica. They mine the leaves of their host plant. The loosened epidermis is bright green at first, later yellowish, and is marked by a broad blackish frass line nearly as broad as the mine. The larvae are very bright green. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Stigmella intermedia is recorded against all the insects logged in Miami (11 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.
