Phyllonorycter memorabilis Wikipedia
Phyllonorycter memorabilis is a moth of the Gracillariidae family. It is known from California, United States.
The larvae feed on Lathyrus species. They mine the leaves of their host plant. The mine has the form of a large tentiform mine on the underside of the leaf. The loosened lower epidermis is white and so much wrinkled at maturity that the leaf is closely rolled over.
