(Braun, 1939)
Phyllonorycter memorabilis is a small in the Gracillariidae, described by Braun in 1939. It is to California, United States. The larvae are leaf miners that feed on of Lathyrus, creating distinctive mines within the leaf tissue.

Identification
As a member of Phyllonorycter, this is a micro- with a wingspan likely under 10 mm. Identification to species level requires examination of genitalia or ; external alone is insufficient to distinguish it from . The is characterized by with narrow, wings and distinctive wing patterns of white or cream markings on a darker ground color. Larval mines on Lathyrus plants may aid in detection.
Habitat
Associated with supporting Lathyrus plants, which include diverse vegetation types in California ranging from coastal scrub to montane meadows and woodland edges.
Distribution
to California, United States. Documented from multiple localities within the state.
Diet
Larvae feed on Lathyrus (Fabaceae), mining the leaves of their plant. feeding habits are unknown.
Host Associations
- Lathyrus - larval Larvae mine leaves of plant
Life Cycle
Larval stage consists of leaf-mining within Lathyrus foliage. likely occurs within the mine or in a silken cocoon on the leaf surface, as is typical for the . are attracted to light.
Behavior
have been observed at blacklight, indicating activity. Larvae are endophagous leaf miners, feeding between the upper and lower leaf .
Ecological Role
As a , larvae create localized damage to plant foliage. The ecological impact is likely minimal given the specialized host relationship and restricted distribution. May serve as prey for and other natural enemies.
Human Relevance
No known economic or agricultural significance. Not documented as a pest .

Taxonomic note
Described by Annette Frances Braun in 1939. The epithet 'memorabilis' (Latin for 'memorable' or 'noteworthy') likely reflects its distinction among related species.
