Description
 
 

Pink underwing is a medium to large sized, strikingly colored, underwing moth. Adults are 1¼ to 1½ in length and have a wingspan of 2 to 3.

The forewings are light gray and brownish gray with thin, black, jagged, antemedial and postmedial lines. The kidney-shaped (reniform) spot is slightly paler than the surrounding background color. The hindwings are pink with a black median band, a black terminal band, and a wide, straight, uninterrupted, white fringe.

The antennae are slender and thread-like.

There is a prominent tympanal hearing organ on each side of the thorax.

Behavior

 
 

Larvae are solitary feeders.

Adults are active at night. They are attracted to light. When at rest the wings are folded roof-like over the body. When approached or disturbed they spread their forewings revealing the startling color of the hindwings, possibly to scare off or give it time to escape a predator.

Larva Hosts

The underwing I saw had orange in place of the pink markings.

The underwing was on my coleus plant on the deck. The orange and black markings were a zig zag pattern. She opened her wings once and I was thrilled to see the colorful  markings. I found the name of this species by pure luck. The internet did not readily have photos of this moth and it’s markings.

There are at least 27 similar underwing moths in eastern North America, 21 of which occur in Minnesota. About half of these have pink or red on the hindwing, half have orange or orangish-yellow. Your underwing was likely one of the latter.
