Spirama

Description

Antennae usually minutely fasciculate in male. Tibia 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. Fore wings with nearly rectangular apex. Hind wings with vein 5 from lower angle of cell, which is rather short.

Defensive display

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 slightly opened mouth. This pattern is more clearly discernible in females. It may intimidate potential predators and dissuade them from attacking.
