Catocala blandula, Catocala crataegi and Catocala mira
are sometimes difficult to distinguish.
C. blandula is perhaps best distinguished from C. mira
in that blandula has a dark brown forewing basal area while mira has a much
lighter basal area.
In crataegi the basal are is black, the median area has a greenish tint
and the hindwing black outer margin is broken near the anal angle.
