I took a photo of this butterfly near NTU, and am having some trouble IDing it. I think it looks like a Malayan Swift, but that's just a guess. Is anyone able to help?
I am afraid this shot present great difficulties.
The shot is rather low-res & blurry.
The antennae which are improtant in ID are hidden.
The main features are.
1 female from the abdominal end & long profile.
2. There appear to be two subapical spots ie spot 6 & 7.
3. There is a gap which is space 5 & below a large pale area suggesting spots in space 4 & 3.
4. There appear to be a couple of spots on the HW.
Probably Isma bononia. Correction Unlikely.
FW spots 3 & 4 are variable in size & in a blurred shot would appear joined together.
The underside HW have spots.
The face is whitish.
The antennae have white patches. http://yutaka.it-n.jp/hes/91990001.html
Even if assuming all the pale marks are due to injury (except the two subapical spots) confirmation of Caltoris malaya will require here the absence of any FW cellspot.
Also, this looks like Baoris sp based on the shape of the antaennae, if I'm not wrong. However, I understand there's no way to tell from the two species based on photos?
