Phyllonorycter tiliacella is a moth of the family Gracillariidae. It is known from Canada (Québec and Ontario) and the United States (including Illinois, Kentucky, New York, Maine, Vermont and Connecticut). The larvae feed on Tilia species, including Tilia americana. They mine the leaves of their host plant. The mine has the form of a tentiform mine on upperside leaf. The mine is white and densely speckled with dark brown. The pupa of the summer brood is suspended in a very slight silken web, in the brood remaining through the winter in the pupal state, a denser cocoon is spun, which is attached above and below.

With luck
About 10% of wildlife watchers report a Basswood Round-Blotch Miner Moth sighting in Boston on a given day, based on 62 verified sightings from GBIF citizen-science data. It is the 220th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Basswood Round-Blotch Miner Moth in Boston on a given day, against under 5% in October to May, the lowest months.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Basswood Round-Blotch Miner Moth sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Basswood Round-Blotch Miner Moth is recorded against all the insects logged in Boston (62 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.
