In 3 days ~10% in a week ~30%
Trifurcula saccharella is a moth of the family Nepticulidae. It is found in Ohio, United States. The wingspan is about 4 mm. Mined leaves may be collected in early July and late August; sometimes the larvae of a third generation are found in October. Moths from the overwintering pupae emerge in May and June.
The larvae feed on Acer saccharum and Acer rubrum. They mine the leaves of their host plant. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Glaucolepis saccharella is recorded against all the insects logged in Boston (46 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.
