Attributes of Sphingicampa heiligbrodti
Identification: Upperside of forewing is light gray with scalloped brown median and submedian lines. Upperside of hindwing is light gray with red at the base which may extend outward over most of the wing. Forewing has small white cell spots, and hindwing has larger black spots.
Wing Span: 2 1/16 - 3 3/16 inches (5.2 - 8 cm).
Life History: Young caterpillars perch on the undersides of petioles and feed on the leaf bases. Older caterpillars cut through petioles partway and bend down the leaves in order to feed on them.
