    Three Caltoris in Singaporehave noticeable pale areas on the antenna.

    1 Caltoris cormasa.
    Female.

    2. Caltoris cahira
    Male.

    3. Caltoris bromus.
    Female.

    Two species have the antenna largely blackish.

    4. Caltoris malaya
    male.

    5. Caltoris philippina
    male.
    https://i13.photobucket.com/albums/a...psf449dfdc.jpg



    1. The FW is raised high enough to indicate no upper cellspot & so by deduction no cellspot at all.
    The individual is rather worn & faded.
    The lack of cellspot inicate Caltoris malaya.


    3 Caltoris malaya female.
    The 2nd pic shows the upperside with no FW cellspot.
    The female is typically mote ochreous ie yellower.


    Post 14 no 5 looks very much like C. malaya & is probably so.
    The HW spot in space 2 may be just an artifact, & not a real spot marking.




    2. Baoris probably Baoris farri.

    Baoris have a longer swept FW with a sinuous margin.
    The antenna appear largely black in side view.
    The abdomen is obscurely banded.

    It is simply assumed the darker one is B. oceia & the lighter brown one B. farri.


    Supposedly B. oceia male & female.

    Supposedly B. farri male.

    This female from Vietnam is correct as B. oceia does occur in Vietnam.

    Hi Dr Seow,

    Does these 2 photos show Caltoris philippina?

    DSC_0795.jpgDSC_0828.jpg

    Largely blackish antennae, does not seem to have cell spots on the forewing, greenish tinge on its head and underside?

    Thank you!

    Hi Dr. Seow,

    Here with another skipper.

    Could this be Pelopidas assamensis? It was way larger than the typical P. mathias or P. agna.

    Thank you!

    Hi Dr Seow,

    Are these photos enough to ID this as Telicota colon?

    POst 28.

    Of the Telicota species T. colon is the easiest to identify.

    Male upperside.
    FW spots 4 & 5 distorted & staggered out, ie spot 5 is set farther out than spot 4.
    Long veinstripes.
    Male brnad palced close to the inner margin of the black space.
    Always a patch of orange at the base of space 2.
    Underside FW clearly shows spots 4 & 5 staggered out & distorted.
    Males.

    Female.
    Spots 4v& 5staggered & not in line as in the male.
    FW cellend bars the upper one much longer.
    Female always lack the orange patch at the base of space 2.

    Hi Dr Seow,

    Here with a new set of skippers from a friend. I am trying my hand at ID-ing them, so would appreciate your assistance to confirm or correct my preliminary IDs.

    Thank you!


    1. Pelopidas mathias? Ground colour looks unevenly shaded.

    279371160_670805010672622_511846373254416622_n-2.jpg

    2. Pelopidas agna? This on the other hand looks pretty even.

    279020962_712814956427822_6255329990941593286_n-2.jpg

    3a. Caltoris cormasa?

    279074392_1010021509622869_1957957826315483443_n-2.jpg

    3b. Caltoris cormasa?

    279284235_405639551378324_3651541161669113056_n-2.jpg

    3c. Caltoris cormasa?

    DSC_0188.jpg

    3d. Pale region of the antenna made me think Caltoris, so perhapsCaltoris cormasa?

    279318092_730489004773795_86717901019169521_n-2.jpg

    3e. Caltoris cormasa?

    279232220_533893141662110_1545757458490096551_n-2.jpg

    3f. Caltoris cormasa?

    279114685_441400837632940_808999942510470927_n-2.jpg

    4. No pale region on antennae, more ochreous UNH so could be C. malaya?

    279029609_3027149147548932_1346532006613479939_n-2.jpg
