Like other Sphinx moths, the Streaked Sphinx is large and has streamlined wings. It is mostly brown with dark brown edging on the thorax. A dark dot sits on either side of the thorax on the wing, and a smudged dot beneath that one. The hindwings are orange and may be concealed by the larger forewings. The inner edge of the forewings has purple streaks which may also run along the veins in the center. Tapered points on the forewings and a curved shape give the moth a sleek profile.

The caterpillar is plump and green with a flat green head lined with a long white stripe on each side. A white line by the rear end extends upward toward a long horn, which looks like a spike or spine. Pale yellow lines run diagonally down the sides of the body on each segment, barely touching a light blue dot. The top of the horn has blue on it as well. The rear end is covered in small black specks. This larva feeds on plants in cashew family.

The Streaked Sphinx keeps to hot, humid, tropical areas like the southern tip of Florida and Mexico. Occasionally, an adult may stray north. It is also found in Central and South America. When flying, its orange hindwings show flashes of color, but when resting on a tree, it may be inconspicuous thanks to its coloring despite its large size.

Butterfly and Moth Anatomy
Graphic showing basic anatomy of a common North American butterfly and moth insect
1
Antennae: Butterflies and Moths have a pair of antennae on the head used for sensing.
2
Head: The head is home to the insect's eyes, antennae, and proboscis.
3
Thorax: Home to the three pairs of legs as well as vital internal organs.
4
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
5
Forewing: The upper, forward wing pair used for flying.
6
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
