TAXONOMY:
Family: Sphingidae, Latreille, 1802 |
Argentina is the specimen type locality.
The upperside of the forewing is dark brown with gray streaks along the inner margin and a gray patch at the tip of the wing. The upperside of the hindwing is dark brown with varying amounts of dark orange at the base.
Erinnyis ello has a lighter forewing than lassauxii; Erinnyis crameri lacks the stripes on the abdomen found on lassauxii .

It is occasionally taken from July-October in Arizona and (December) Texas, and in September in south Florida.
During the night adults nectar at flowers, including bouncing bet (Saponaria officinalis). Valerie G. reports them on talayote (Cynanchum racemosum), a milkweed vine, November 7, 2009, at the Zilker Preserve, Austin, Travis County, Texa. The found larva pupated in November and the adult moth emerged on December 19, 2009.

"He says you may be interested in my pics of it for your site, so I am getting in touch with you. You can see the two pics I posted to Bugguide for ID. I have about thirty pics I of it. It is the most unusual caterpillar I have seen here. It was on a large Fringed Twinevine next to the runway. I am wondering if the white protuberances on its head would be from ingesting the sap of the Twinvine, and would make it poisonous."
Tzila "Z" Duenzl
I reply, "Z, Please let me know if you (sighting location) are in Hill County or Parker County. I do not know what causes the white protuberances. You are at about northern limits of its range in Texas. Thanks. Very nice photos. I need the county so I know what section to post it in. Yes, it is Erinnyis lassauxii.
