Larval substrate: Vitis* (Grape), Parthenocissus* (Virginia Creeper)
Phenology: Adult: 6/28 to 10/15 (206 records)
Comment: Forewing measurements have been given as 12-16.4mm, but Massachusetts male specimens tend to be in the range 15-17mm. The females of both E. diversilineata and E. gracilineata are slightly larger than the males and female E. diversilineata can be as large as female E. gracilineata. Except for smaller than average male diversilineata (less than 15mm FWL) and maybe very large female E. gracilineata (greater than 19mm FWL), size cannot be reliably used to distinguish the species. Larvae are mostly greenish, often tinged with red. They lack the darkly pigmented lateral swellings on the second thoracic segment found in E. gracilineata. For hints on how to identify this species, see the photo and the next species' account.
