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).[1]
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.
