Crambid Snout Moths vary in appearance, but Herpetogramma sphingealis goes a step further, looking different based on gender.
Male Herpetogramma sphingealis moths are shaped somewhat like Sphinx moths with slightly elongated wings whereas females are more square-shaped. Both are a shade of brown with females having a paler, faded hue. A luster, or sheen, covers both sexes that gives the wings a glassy look. A pale spot at the outer edge of each forewing may be roughly bordered in dark brown. This species does not show clear lines crossing the body like its similar-looking relatives. The hindwings have white fringe near the body and the forewings have a spot of white on their fringe where they meet the hindwings. The rest of the fringe is brown. The ventral (belly) side of the moth is white.
Caterpillars of this species of Crambid Snout Moth eat the fronds of Christmas ferns. Adults are on wing from May through early autumn. They can be found in darker, shady areas of forests.
