The egg chorion was investigated for 15 species of sod webworm moths (Lepidoptera: Pyralidae: Crambinae) collected in Tennessee. Liquid plastic was used for surface printing of chorion sculpturing. Scanning electron micrographs were utilized in construction of a taxonomic key to eggs of the Crambinae species studied and the characteristics illustrated.
