The rare and possibly endangered Proud
sphinx, Proserpinus gaurae
(Wing span: 1 3/4 - 1 7/8 inches (4.5 - 4.8 cm)), flies from
Texas and Louisiana east to northern Florida, north to Alabama,
Missouri, northern Georgia, and South Carolina. It may or may not range as far south as northern Mexico.
The abdomen may have a pale band running across the rear. The wings are brown. The forewing sometimes has a
greenish tint and may have the median area darker. The lines bordering the median area are curved.
The hindwing has a reddish brown border.
Proserpinus gaurae adults probably fly as one or two flights, from April-August.
Adults fly during the afternoon, nectaring from flowers.
Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.
SCENTING AND MATING:
Females call in the males with a pheromone released from a gland at the tip of the
EGGS, LARVAE, PUPAE:
Eggs hatch about 10 days after the female deposits them on the host plant,
and the newly-hatched caterpillars eat their eggshells.
Larvae feed on evening primrose (Oenothera), Gaura, and willow weed (Epilobium), all in the evening primrose
