Skipper ID request

[Zicky]

Dear Doctor Seow,

Here are some new skipper

1 - BIGGUY1.1.jpgBIGGUY1.2.jpgBIGGUY1.3.jpg
This skipper is the size of a caltoris, big as a biden pilosa. FW vein looks lightly darken with abdominal black band. Is it a P.serina?

2 - brownguy1.1.jpgbrownguy1.2.jpg
This caltoris/boaris species is not brownish red, and somewhat greyish brown. Not so confident but i suspect is a caltoris species

3 - smallguy1.1.jpgsmallguy1.2.jpg
FW spots distinctly yellow, Polytremis lubricans?

4 - tinguy1.1.jpgtinyguy1.2.jpg
Potanthus omaha? The forewing is lightly darken at submarginal area and veins are somewhat dark

Regards
Zick

Hi Doctor Seow,

Can i clarify what do you mean by ground colour? Is it refering to a specific part of the skipper, or just the colouring of the skipper in general?

Thank you!

The ground colour is the background colour as against the colour of any markings on it.

For examples.
The ground colour is blue-black with parallel stripes of ashy blue on both wings.

The ground colour is heavily dark-shaded.

The orange HW band contrast strongly with the ground colour.

The HW band barely contrast with the ground colour.

On this note, i would like to inquire how do i differentiate Caltoris philippina and Polytremis lubricans?

Im still relatively new at IDing skippers and these two gives me a very hard time. Both shares similar colouration and course scaling,and i feel that from pictures the spots seem to appear in the wings of both species as well

Would like to inquire how can i learn to differentiate both

Regards
