Leucanthiza amphicarpeaefoliella
Clemens, 1859
Leucanthiza amphicarpeaefoliella is a minute leaf-mining in the Gracillariidae, described by Clemens in 1859. The occurs in northeastern North America, with records from Ontario and Québec in Canada and several eastern and midwestern U.S. states. are small with a wingspan of approximately 8 mm. The larvae are specialized leaf miners on Amphicarpaea bracteata, a leguminous vine.

Identification
The can be distinguished from other North American Gracillariidae by its association with Amphicarpaea bracteata as the sole known larval . The small size (8 mm wingspan) and geographic range in northeastern North America are supporting characters. The leaf mines on hog-peanut (A. bracteata) are diagnostic for the stages. Separation from other Leucanthiza species requires examination of genitalia or molecular data.
