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 .

Similar Taxa

  • Other Phyllonorycter speciesNumerous occur in North America; external overlaps substantially, requiring dissection or molecular methods for reliable identification.
  • Cameraria speciesAlso Gracillariidae leaf miners, but typically create blotch mines rather than the linear or tentiform mines of Phyllonorycter; differ in wing venation and pattern.

Taxonomic note

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