Post 4.
This is badly off focus, but the shape & arrangement of the HW postdiscal spotss 5, 6, & 7 & the V spot in space 1b indicate it is A. epimuta.

Usually there is a tiny white spot in the cilia near the black spot.
This can be very poor in worn specimen eg.

Caltoris can be a rather difficult genus to ID as much depend on the colouration.
In photos it can varies enormously.


Caltoris cormasa
Underside strongly red/purple brown, the HW usually darker.
Occassionally most of the FW spots may be absent except for spots 2 & 3.
Typical example.

Caltoris bromus.
Underside dark brown with an ochreous overlay. FW upper cellspot should be prominent. Female often with extra HW spots.

Caltoris cahira.
Very similar to C. bromus but underside HW dark chocolate.

Caltoris malaya.
FW without cellspot, so no upper cellspot visible from the underside.
Underside light rusty brown in male.
Probable male.
