The perennial Ludwigia octovalvis is found in marshes, and is common nearly throughout the state of Florida. The plant is also located in Georgia, Alabama, Louisiana, Mississippi, North & South Carolina, Texas, Hawaii, Puerto Rico and the Virgin Islands.

The following "American" Sphingidae utilize Ludwigia octovalvis as a larval host.

Eumorpha fasciatus

The larva of this species grows to be quite large, at least four inches long, and shows several different forms, from almost all green to red, yellow and green with narrow black bands. Sometimes several forms are found in very close proximity, even on the same plant.

I have also seen larvae, about ready to pupate, that were almost all red. In all cases, however, the white oblique lines were present with relatively large, dark spiracular circles intersecting the lines.
