Coptodisca powellella
Opler, 1971
Coptodisca powellella is a small in the Heliozelidae, described by Paul A. Opler in 1971. It is to California and is associated with coast live oak (Quercus agrifolia). The larvae are leaf miners, creating distinctive feeding patterns within the leaves of their plant.

Identification
Distinguished from other Coptodisca by geographic restriction to California and specific association with Quercus agrifolia. Leaf mines on coast live oak with associated specimens provide the most reliable identification. Genitalia dissection may be required for definitive species-level identification.

Life Cycle
Larvae mine leaves of Quercus agrifolia. Specific details regarding placement, site, number of per year, and stage are not documented.
Behavior
Larvae create internal leaf mines in Quercus agrifolia foliage. is not described in available sources.
Ecological Role
As a , larvae may contribute to localized reduction in photosynthetic capacity of leaves. -level impacts on Quercus agrifolia are not documented. Serves as a herbivore in oak-associated .
