Identification
Identified by its association with specific California oak and the distinctive larval leaf mines: ovoid, opaque brown, crossing the midrib, consuming 60–90% of leaf surface, with two folds (rarely one) that bow the leaf upward with a sunken central area. The specific epithet references serpentine soils, linking it to host plants on such substrates.
Appearance
Small with forewings measuring 3.2–4.2 mm in length. Specific coloration and pattern details are not documented in available sources.
Habitat
Associated with serpentine soil where oaks occur. Host plants include Quercus douglasii, Quercus dumosa, Quercus durata, and Quercus × alvordiana.
Distribution
to California, United States. Known from serpentine soil regions supporting its oaks.
Diet
feed on leaves of Quercus douglasii, Quercus dumosa, Quercus durata, and Quercus × alvordiana. do not feed; specific adult diet is not documented.
Host Associations
- Quercus douglasii - larval
- Quercus dumosa - larval
- Quercus durata - larval
- Quercus × alvordiana - larval
Life Cycle
Larval stage creates leaf mines on oaks. Mines are solitary, ovoid, with opaque brown , crossing the midrib and consuming 60–90% of leaf surface. Mines typically have two folds (rarely one) that are not necessarily parallel. occurs within the mine. Specific timing of life stages is not documented.
Behavior
are solitary . Each mine contains a single larva. The mining causes the leaf to bow upward with a sunken area at the middle.
Ecological Role
on California native oaks. The specific association with serpentine soil suggests potential role in these specialized , though detailed ecological impacts are not documented.
Human Relevance
No documented economic or agricultural significance. The is of interest to entomologists studying California's serpentine soil and oak-associated fauna.
Similar Taxa
- Cameraria spp.Other Cameraria are on oaks; C. serpentinensis is distinguished by association with serpentine soil oaks and specific mine characteristics (solitary, ovoid, midrib-crossing, two folds, 60–90% leaf consumption). The name itself indicates serpentine soil association.

Etymology
The specific epithet serpentinensis derives from serpentine soil, the substrate on which one of its plants occurs. This naming reflects the ' ecological association with this distinctive California type.
