Identification
Small size (8 mm wingspan) distinguishes this from larger Gracillariidae. Association with Arbutus menziesii plant provides a key identification clue within its range. The is one of several Phyllonorycter in western North America; precise identification may require examination of genitalia or larval mine characteristics.
Appearance
Wingspan approximately 8 mm. As a member of Phyllonorycter, are small with relatively broad wings compared to body size. Coloration and pattern details are not well documented in available sources.
Habitat
Associated with Pacific madrone (Arbutus menziesii), indicating woodland or forest where this tree occurs.
Distribution
Known from California, United States and British Columbia, Canada. Records suggest a Pacific coastal distribution corresponding to the range of its plant.
Diet
Larvae feed on Arbutus menziesii (Pacific madrone). They mine the leaves of their plant. feeding habits are not documented.
Host Associations
- Arbutus menziesii - primary Larval food plant; leaves are mined
Life Cycle
Larvae mine leaves of Arbutus menziesii. Specific details of , , and timing are not documented.
Behavior
Larvae create leaf mines in plant foliage. are attracted to light based on observation of congeneric .
Ecological Role
As a , larvae may contribute to nutrient cycling and serve as food for . impacts on plant are likely minimal given the specialized but presumably low- relationship.
