All three photos are of the same specimen.

My thanks to Dr. Jean-François Landry of Agriculture Canada for identifying the specimen illustrated above, which was collected and given to the Canadian National Collection in Ottawa.  For further information on Crocidophora serratissimalis, I have relied on 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), and 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 serratissimalis has pale straw-colored wings with light brown markings.  On the forewing, the postmedial line has only a slight outward curve below the costa, then bulges strongly outward in the middle of the wing; below the bulge, the line to the inner margin is fairly straight with two scallops.  On the hindwing, the postmedial line describes a fairly smooth curve.  On both forewing and hindwing, the subterminal line is strongly toothed, an aid to distinguishing this from other similar species.  There is a fine, brown, continuous terminal line in both forewing and hindwing.  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 wingspan from 18 to 25 mm.

Munroe (1976) notes that the larva of Crocidophora serratissimalis has been reared on cut-grass (Leersia oryzoides).  Forbes (1923) indicates an adult flight season from June to September.

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