Appearance
The wingspan is 7.5–8 mm. The forewings are uniform orange-ocherous or sometimes brownish. The hind wings are grey or pale reddish fuscous. Adults have been recorded on wing from April to September.
Naming
The species was described in 1860 by James Brackenridge Clemens.
Food
The larvae feed on ''Betula nigra''. They mine the leaves of their host plant. The mine is thread-like and irregularly winding. It is filled with blackish frass. Older larvae live freely, feeding on the underside of the leaf. Mature larvae are pale green with a reddish tinge. Pupation takes place in a pale to brownish ocherous cocoon.References:
