Spirama is a genus of moths in the family Erebidae first described by Achille Guenée in 1852.
Antennae usually minutely fasciculate (bundled) in the male. The tibia is not hairy and mid-tibia spined. Palpi with second joint reaching vertex of head and third joint naked. Thorax and abdomen smoothly clothed with hair. Forewings with nearly rectangular apex. Hindwings with vein 5 from the lower angle of the cell, which is rather short.[1]
Some of the species, such as S. helicina, S. indenta, S. recessa, S. remota and S. sumbana, have a pattern on the wings that looks like the frontal view of the face of a snake with a slightly opened mouth. This pattern is more clearly discernible in females. It may intimidate potential predators and dissuade them from attacking.[2]
