Identification

This 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.

 
Similar
Species

Darling underwing (Catocala cara) forewings are darker grayish-brown and violet-brown. The fringe on the hindwing is undulating or checkered.

Once-married underwing (Catocala unijuga) forewing reniform spot is dark and there is a whitish spot in front of it. The subterminal jagged line has a broad, whitish outline in front. The fringe on the hindwing is undulating.


Larval Food

Leaves of poplar (Populus spp.) and willow (Salix spp.).

 
Adult Food

 

 
Life Cycle

Eggs overwinter.

 
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.
