Catocala similis, the Similar Underwing (wingspan: 35-45mm), flies from Ontario and Quebec south through Maine and Connecticut to Florida, west to Texas and Oklahoma and north to Minnesota.
The pale triangular patch from the postmedial line along the costa, pointed at the apex, and the light-coloured, tear-shaped reniform spot distinguish this species. Tim Dyson photo.
The subreniform spot also projects considerably beyond the reniform anteriorally at a right angle to the line of the subreniform.
It has also been recorded in Alabama, Arkansas, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Wisconsin and West Virginia.
Many specimens also have a small, light coloured, flattened oval spot about halfway between the pm and am lines at about the midpoint of the reniform spot. The pm line is almost straight for most of its length.
