Synonyms and other taxonomic changes
Eulithis Hübner, 1821
Numbers
14 species in North America listed at All-Leps

Identification
A text description is needed that explains how to reliably distinguish photos of the two common species mentioned above; the description given in Covell's Guide (1) is not sufficient.
Please place all diversilineata and gracilineata images here unless you have reared the adults from caterpillars or have dissected the adults.
Remarks
Several species show considerable color and pattern variation among individuals, making identification by sight more difficult.
See Also
The adults of two common species are very similar and frequently confused: E. diversilineata (Lesser Grapevine Looper) and E. gracilineata (Greater Grapevine Looper). See link to comparison images below. Any text description that explains how to reliably distinguish these two species by sight would be welcome and appreciated.
