Pink-spotted hawkmoth is a very large sphinx moth. It is native to South and Central America. It migrates north each year to the eastern, central, and southwestern United States, rarely as far as southern Canada. It is a rare stray to southern Minnesota in late autumn. Larvae feed both day and night on the underside of leaves of plants in the Potato (Solanaceae) and Morning Glory (Convolvulaceae) families. Adults are found in a wide range of habitats but especially disturbed areas and agricultural areas. They are active at night and will come to lights. They feed on the nectar of many deep-throated flowers, including petunia, morning glory, and sweet potato.

Adults are 2¼″ to 2⅝″ (55 to 65 mm) in length and have a 3¾″ to 4¾″ (95 to 120 mm) wingspan. The forewing length is 19⁄16″ to 25⁄16″ (40 to 58 mm). The body is robust.

The eyes are very large. The antennae are mostly white with a brown stripe on the upper side.

The abdomen tapers in the rear to a point. There is a broad, brown, longitudinal stripe in the middle (middorsal). The front half of each abdominal segment is bright pink, the rear half is black. This is the feature that gives the moth its common name and distinguishes it from all other moths in our area.

The forewing is long, narrow, and pointed. The upper side is strongly mottled brown, grayish-brown, or brownish-gray. The median area is dark and has a small kidney-shaped spot (reniform spot) and two long black dashes behind the spot. The reniform spot is gray or white, and outlined with black. There are more black dashes in the subterminal area. The antemedial (AM) and postmedial (PM) lines are each represented by two jagged black lines. The subterminal (ST) line is black and often incomplete.

The hind wing is bright pink at the base, gray in the postmedial area, and brown in the subterminal and terminal areas. It is crossed with three thick black lines, the innermost curved and almost heart-shaped, the outer two wavy.

Total length: 2¼″ to 2⅝″ (55 to 65 mm)

Wingspan: 3¾″ to 4¾″ (95 to 120 mm)

This is the only species in Minnesota that has pink spots on the abdomen. There are no similar species.

A wide range of habitats, especially disturbed areas and agricultural areas

One generation per year: Late fall in Minnesota

In other areas, two or three generations per year.

Adults are active at night

The female lays a single egg on the underside of a leaf of a host plant. The larva feeds day and night. When mature it drops to the ground, burrows below the surface, creates a chamber, and pupates.

Plants in the Potato (Solanaceae) and Morning Glory (Convolvulaceae) families

Nectar from deep-throated flowers, including morning glory, sweet potato, and petunia
