Coptodisca lucifluella is a moth of the family Heliozelidae. It was described by Clemens in 1860. It is found in North America, including Kentucky and Ohio. The larvae feed on Carya illinoinensis. They mine the leaves of their host plant. The mine has the form of an oval blotch. Full-grown larvae chew the upper and lower leaf epidermis around the edges of the mine before pupating inside it.
