The Blinded Sphinx caterpillar grows to approximately 3 inches. The body is bright green and covered with prominent white granules. Some forms have wine-red spots surrounding the spiracles. The front of the head is flattened and rimmed with a pale line. The caudal horn is green and extends from abdominal segment 8. A white or yellowish oblique line extends forward from the base of the horn ending near the anterior margin of abdominal segment 7. Pale, thin oblique lines form V-shapes on the top of the abdomen. This caterpillar is highly variable and can be difficult to recognize in early instars. The adult moth has a wingspan of 3.75 inches. The wings have scalloped outer margins. The forewing is brown and tan. The hindwing is tan and bright pink. There is a large black spot near the inner margin of the hindwing that has a blue spot with no central black spot or “pupil” inside. Hence, the name Blinded Sphinx.
