Caloptilia diversilobiella is a moth of the family Gracillariidae. It is found in the United States (California).[1]
The eggs of this moth are laid on oak (Quercus) leaves. When hatched, the larva at first mines the leaves in a gallery leading to a blotch. The larva then form cones by folding the tips of the leaves, and feeding within.[2] The larvae feed on poison oak (Toxicodendron diversilobum).
