Caloptilia agrifoliella
Opler, 1971
Caloptilia agrifoliella is a leaf-mining in the Gracillariidae, described by Opler in 1971. The is known exclusively from California, where its larvae feed on Quercus agrifolia (coast live oak), creating distinctive mines within the leaves. Like other members of the , are small moths with characteristic resting postures and are attracted to ultraviolet light sources.

Identification
of Caloptilia agrifoliella are small typical of the Caloptilia, which are recognized by their narrow, often mottled wings and characteristic resting posture with wings held roof-like over the body. Definitive identification requires examination of genitalia or association with the larval plant Quercus agrifolia, as external overlaps with numerous . The may be distinguished from other Caloptilia by its restricted geographic range and confirmed host association, though precise diagnostic features for field identification are not documented.
Habitat
Associated with stands of Quercus agrifolia (coast live oak), the oak in coastal California and the foothills of the Coast Ranges. The species occupies Mediterranean-type characterized by hot, dry summers and mild, wet winters.
Distribution
United States: California. Records from British Columbia, Canada appear in distribution databases but require verification; the may be restricted to California.
Diet
Larvae feed on Quercus agrifolia (coast live oak), mining within the leaves. feeding habits are unknown.
Host Associations
- Quercus agrifolia - larval Larvae mine leaves of this oak
Behavior
Larvae are leaf miners, feeding internally within Quercus agrifolia leaves. are and have been observed at ultraviolet light sources.
Ecological Role
As a , larvae create internal feeding galleries in oak leaves. The ecological impact on plant has not been quantified.
