Dear Dr Seow, is this the Full Stop Swift (Caltoris cormasa)? Thanks

[Psyche]

Post 4.

Yes, a female Caltoris cormasa.

This species have a redder tone to the UnH brown in photos. FW spots are yellowish.

The UpF shows a single cellspot ,which is stated to be usual, thus called the Fullstop Swift for the single spot.
However, many Singapore examples often have a second tiny upper cellspot.

Male have a rounder FW apex. Female a more pointy apex & a longer profile.
Two males , one female.
