My initial identification of Crocidophora tuberculalis was based on Covell (1984), and subsequently checked against Munroe, E., in Dominick, R.B. et al., The Moths of America North of Mexico, Fascicle 13.2A, Pyraloidea Pyralidae (Part) (London: E.W. Classey, 1976).  I have also relied on Forbes, William T.M., The Lepidoptera of New York and Neighboring States, Primitive Forms, Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell University, 1923).

Crocidophora tuberculalis has light straw yellow, somewhat translucent wings with gray-brown markings.  The postmedial and subterminal lines are similar on both forewing and hindwing.  The postmedial line is somewhat sinuous on the forewing, but without any pronounced bulges; on the hindwing it is fairly smoothly curved.  On both forewing and hindwing, the subterminal line is a smooth broad curve of gray-brown, slightly thicker towards the apex.  Munroe (1976) notes that the forewing of male Crocidophora species has a large fovea, or hollow, in and behind the cell of the forewing.  Forbes (1923) indicates a 15 mm wingspan for this species.

The early stages of Crocidophora tuberculalis are apparently unknown.  According to Munroe (1976) and Forbes (1923), adult moths fly in June and July in my general area.

My records to date for Crocidophora tuberculalis (each date representing "the night of") are in the table below:
