Subspecies editha Edwards, 1875, is found in western portions of range. In "Systematics of Moths in the Genus Catocala (Noctuidae). III. The Types of William H. Edwards, Augustus R. Grote and Achille Guinee", by Lawrence F. Gall and David C. Hawks, Journal of the Lepidopterists Society, Volume 56 Number 4, 9 December 2002, editha is placed as a synonym of amatrix. Moths respond to lights and to bait, much better to bait according to Sargent.
Similar species: This moth is somewhat similar to C. cara, and it is believed they will hybridize in the wild on occasion.
Catocala amatrix are usually on the wing from August to October in southern Quebec with earlier flight further south.

Sargent suggests the name "hesseli" for melanic specimens in honour of Sidney A. Hessel.
Form "selecta" lacks the diffuse black bar running from the basal area to the apex as depicted in the specimen to the right, courtesy of Robert Muller, Connecticut.
"Pallida" Barnes and McDunnough, 1918, is a very pale form.
This species is very skittish and frequently hides in caves, under bridges, under tree bark, etc. by day, resting with head down.
Camouflage on tree bark is well illustrated in the Cindy Mead (Michigan) image to the right.
The Catocala amatrix caterpillar shows a preference for poplars and willows.
