Tischeria quercitella
Tischeria quercitella, the oak blotch miner moth, is a moth of the family Tischeriidae. It has been sighted in North America in Ontario, District of Columbia, Illinois, Kentucky, Massachusetts, Missouri, New Jersey, Ohio, Pennsylvania and Virginia. The larvae feed on "Castanea dentata", "Quercus alba", "Quercus ilicifolia", "Quercus prinus" and "Quercus velutina". They mine the leaves of their host plant. The mine consists of a distinctive upperside blotch. It is the only species of the oak-feeding group of North American "Tischeria" species that constructs a nidus as a pupal chamber within the mine.
