Cameraria temblorensis is a moth of the Gracillariidae family. It is known from California, United States. The length of the forewings is 3-4 mm. The larvae feed on Quercus douglasii, Quercus dumosa, Quercus dumosa × engelmanii, Quercus engelmannii, Quercus turbinella and Quercus × alvordiana. They mine the leaves of their host plant. The mine is ovoid. The epidermis is opaque, yellow green. Mines normally cross the midrib and consume 30%-95% of the leaf surface. The mines are solitary and normally have two folds, although occasionally there are three. The folds are parallel or at slight angles.
