Psidium guajava
The larvae feed on "Eugenia axillaris", "Psidium guajava" and "Psidium guineense". They mine the leaves of their host plant. The mine has the form of a narrow serpentine track on the upper side of the leaf, later broadening into a large irregular blotch mine. The upper epidermis turns white and makes the mines very noticeable at a distance.
