Catabapta subnata (4)
Explanation of Names
Specific epithet from Latin possible meaning "to arise, grow up."
Lafontaine & Schmidt (2010) included 101 species of the genus Catocala in America north of Mexico. (5)
Powell & Opler (2009) reported 110 species in all of North America, and about 230 worldwide. (6)
Wingspan 75-90 mm. (7)
Adult - forewing grayish with well-defined AM and PM lines, having significant brown scaling in post-median area bordering distal edge of PM line and sometimes in AM area; reniform spot large and reddish-brown; subreniform spot round to pork chop shaped and can be open or closed (i.e. no elongated "tail" extending to subterminal area); Males lack black basal dash, while it may (usually) or may not be present in females; head and thorax grayish while abdomen is orange/yellow dorsally. Hindwing with broad black and yellow/orange bands, as in several other Catocala species.
Eastern North America.
Lectotype male: Maryland. (8)
Adults on the wing July-Sept
Walnut, butternut, hickory. (7)

Catocala neogama is often indistinguishable by photo from subnata. However, male subnata lack the black basal dash that is present in neogama allowing any image of a specimen without the black basal dash to be identified as subnata. Outside of dissection or sequencing, specimens with the black basal dash can only reliably be identified by examination of the hind tibia:
subnata; cylindrical with ventral surface densely covered with evenly distributed spines
neogama; compressed/flattened with ventral surface sparsely covered with sporadically distributed spines
Comparison of spines of subnata (top), and neogama (bottom):
