Baoris or Caltoris??

Another shot of those zippy brown skippers. :grin2: :grin2:
Could it be a Baoris or Caltoris? :hmmm: :hmmm:

Salient points.

1 Male.
2 Rather large elongate upper cell spot; this means the lower cell spot will be present also, ie. two cell spots.
3 Underside hindwing dark purplish brown.

In the Baoris male, either the upper cell spot is absent or rather small.
Based on this, it is more likely to be a Caltoris.

In Caltoris cormasa & C. sirius male either the upper cell spot is absent or a tiny dot. They can be ruled out immediately.

This leaves the 3 species with 2 cell spots, namely C. brunnea, C. bromus, & C. cahira.
C. cahira have a very dark chocolate underside.
C. bromus have the underside hindwing ochreous.
C. brunnea have the underside hindwing dark purple brown.

Thus this is most likely to be C. brunnea.

I did a recheck. This is just plain old Baoris oceia. I recalled another individual in which the upper cell spot was also elongate, but a proven Baoris. The underside hindwing colouration also matched.

Nelson: Been experimenting with your system and am reasonably happy with the results. It does do more searching than I'm used to, but it's easy to put it on manual and move quickly. I'm experimenting with different aperture settings. I also received my T180 and will be experimenting with that too. Looking forward to sending you guys some butterfly shots before too long. William

Thanks Again Seow for your detailed analysis.

William: Looking forward to see some butterfly shots from you soon with your new arsenal of gear. :grin2:

Have fun with your T180. :cheers:

Beautiful photo, especially those fluorescent colors on its head!

I revive this old thread to ask the same question:

You certainly brings up a very difficult old problem.

What you have is a female & should be a Caltoris.
It is less bulky and the antennae are also noticeably paler below the clubs.
The underside hindwing is more evenly brown without the dark shading in B. oceia.
Baoris farri is very close but note the antennal colouration.
Examples of Baoris farri.

There is a big upper cell spot seen meaning there will be 2 cell spots.
Of the 3 Caltoris with 2 big cell spots, C. cahira is very dark brown & C. brunnea is very deep purple brown on the underside hindwing.
C. bromus have ochreous shading and is relatively common.
Examples of C. bromus are.

It should be C. bromus but I am not absolutely certain.

maybe this other pic could help:

This is much better.
I would say I am 90 % certain it is C. bromus.
In hindsight I am able to ID Federick's post 5 pic. as a female Baoris oceia here for comparison.

Thank you again Seow for the explanations :cheers:
