Habitat
Associated with manzanita (Arctostaphylos) stands, which occur in chaparral, woodland, and coastal scrub in California. The 's distribution is tied to the presence of its plants.
Distribution
Known from California, United States. GBIF records indicate presence in California and Arizona, though primary documentation is from California.
Diet
Larvae feed on Arctostaphylos glauca and Arctostaphylos manzanita. They mine the leaves of their plant, creating internal feeding tunnels.
Host Associations
- Arctostaphylos glauca - larval food plant
- Arctostaphylos manzanita - larval food plant
Life Cycle
Larvae are leaf miners. Complete details are not documented in available sources.
Behavior
Larvae mine leaves of plants. is not described in available sources.
Ecological Role
As a , larvae create feeding damage within leaf tissue of manzanita . Their role in broader function has not been studied.
Similar Taxa
- Other Phyllonorycter speciesMany Phyllonorycter are externally similar; reliable identification requires dissection or molecular methods. plant association with Arctostaphylos may help distinguish P. manzanita from sympatric species.
