Hodges Number
7196
Synonyms and other taxonomic changes
Eulithis diversilineata (Hübner, [1813])
Petrophora diversilineata Hübner, [1813] (pl.206)
* phylogenetic sequence #211000
Size
Wingspan 28-33 mm. (1)
Identification
A text description is needed that explains how to reliably distinguish photos of this species from the similar Greater Grapevine Looper (Eulithis gracilineata). See sample images of both species in link below.
Do not place images here unless you have a valid reason for doing so! Adults of diversilineata and gracilineata cannot be separated without rearing or dissection.*

* The forewing measures of the Greater and Lesser essentially do not overlap (Lesser 12-15 mm; Greater, 16-19 mm). Thus, this is a case where photographs with a millimeter rule are not only useful but crucial for photo identification. Compare these images of Lesser (left) and Greater (right).
Food
Larval hosts are grape and Virginia creeper (Parthenocissus quinquefolia, Vitaceae). (1)
