Skippers ID clarification in Singapore

[Psyche]

Post 91.

Yes. This is a fine example of a male Caltoris bromus.

Caltoris bromus.
Antenna with prominent pale area.
FW subapical spots typically two.
FW cellspot two.Very rarely the upper cellspot may be reduced or absent.
UnH uniformly brown with ochreous overlay.
The female is the only species here that may have HW spots in space 2 & 3.

Examples of males in Singapore.

Female.

Caltoris cahira is similar but the UnH is uniformly dark chocolate.

It is much rarer in Singapore.

Hi Dr. Seow,

Seeking your assistance to verify the IDs of the following skippers. Thank you!

1. Could this finally be Pelopidas conjunctus?

Almost as large as my thumb; HW cell spot present; HW spots white & FW spots appear yellow.

Attachment 28198

2. Baoris sp.? Maybe B. farri?

Attachment 28199

3. Caltoris cormasa?

Attachment 28200

4. Caltoris malaya?

No pale regions on antenna, no FW cell spot and appear yellowish.

Attachment 28201

5. Could this be Caltoris bromus?

This would be Caltoris bromus female.
Note also in Caltoris bromus & malaya the FW & HW ground colour are about the same.
In C. cahira & cormasa the HW is a deeper darker shade.

Addendum Here the male C. bromus is without HW spot & the female usually but not always have them.
A recent study in Nepal 2022, shows both sexes (?always) have HW spots .
It is thus possible that the occasional male here may have HW spot.

1. Pelopidas conjuctus male.
FW spots yellow & at least twice as large as the white HW spots.
Upper cellspot if visible often large & oblong.
Many misidentification on the web.

Males.

P. mathias male & female. Note FW spot size.

2. Baoris female presumbly B. farri.
The pale patch at the HW cellend is diagnostic if present.
Note also the more strongly banded abdomen.
In other countries, B. farri female (& often male as well) is fully spotted thus the name Complete Paintbrush Swift.

In Singapore most females are not fully spotted. So an element of doubt here.

3. Caltoris cormasa male.
Typial example. Note the reddish tone.

4 Caltoris malaya male.
The male is rusty brown & the paler female ochreous brown.

Hi Dr. Seow,

Please help to ID for the following butterflies. Thank you!

1. Miletus symethus?

Sorry for the far photo.

DSC_3607.jpg

2. Pelopidas agna?

DSC_3649.jpg

3. Looks to be a different subspecies of Idea leuconoe from Idea leuconoe chersonesia.

Would you be able to differentiate which subspecies this is? Likely an escapee from the zoo.

1. Miletus symethus .Female.
Note white shadings at apex of FW & HW.

2. Typical Pelopidas agna male.
Note uniform ground colour without irregular shadings.

3. Idea leuconoe clara.
The usual ssp kept in Butterfly houses is ssp clara from Taiwan.
The interneural (between the veins) arrowheads on the HW are very small.
There is probably an escapee population in Singapore.

Ssp. clara.
