Phyllonorycter lucetiella
In 3 days ~20% in a week ~30%
Phyllonorycter lucetiella is a moth of the family Gracillariidae. It is known from Québec in Canada and Illinois, Kentucky, Pennsylvania, Florida, Georgia, Maine, Maryland, Michigan, New York, Vermont, Connecticut and Massachusetts in the United States.
The wingspan is 6–7 mm. The larvae feed on Ostrya virginiana and Tilia species (including Tilia americana, Tilia x vulgaris and Tilia × europaea). They mine the leaves of their host plant. The mine has the form of a tentiform mine on underside of leaf, but it is conspicuously visible on the upperside of the leaf, due to removal of green parenchyma tissue from the upper wall. The mine is rectangular, often nearly square, and placed between two veins and unwrinkled. When complete, the mine is transparent, and the pupa, which is contained in an oval cocoon, is plainly visible. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Basswood Miner Moth is recorded against all the insects logged in Boston (64 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.
