    Hi Dr Seow,

    Managed to uncover this photo in my archives.

    Could this be Rapala damona?

    Yes. It is a female Rapala damona.

    The two R. suffusa & damona are closely similar.
    HW with the postdiscal band in space 1b, above the speckled patch arched or domed.
    FW postdiscal band distinctly curved in toward s the costa.

    Rapala suffusa.
    HW speckled patch in space 1b usually occupy half or less of the marginal zone.
    Orange crown in space 2 not visible, merging with the ground colour.
    Males.

    Hi Dr Seow,

    Can I check if this skipper is Parnara bada?

    Yes. It is.
    PARNARABB.png

    Parnara species.
    antennae short & the clubs thick.
    UpF subapical spots 6 & 7in line; if spot 8 is present, it is usually also in line.
    UnH may have a diffuse cellend spot.
    UnH spot 7 is always absent.

    Two known species in Singapore.


    Parnra bada.
    unH spots variable & may be entirely absent.

    Parnara ganga.

    Probably this below is Parnara ganga.
    FW spot 3 is oblong & seem nearer spot 2,( the margins of spot 2 blurry) & UnH spots relatively large.

    Hi Dr Seow,

    Could you help to shed light on what this Arhopala could be?

    Thank you.

    This practically certain to be a female Arhopala milleri.
    Note the longer palpi (labial palps) The abdominal end with a longer slant cut.
    Compare with a male A. sublustris given below.



    Three species recorded in Singapore are very similar & almost impossible to identify correctly.

    A. sublustris is the most common
    UnF postdiscal band uppermost spot 9 is typically dislocated & shifted inwards on the costal margin.
    UnH spot 6 widest at the top & tapers down wards.
    Male upperside bright blue, more reflective.
    Female with HW brown border wide. FW blue not reaching the tornal margin, brown border being uniformly broad
    https://yutaka.it-n.jp/lyc4f/82170010.html
    This is likely A. sublustris male.
    https://www.inaturalist.org/observations/189202433
    See Otsuka L206.


    A. milleri.
    UnF postdiscal band spot 9 less dislocated ,sometime in line with the rest.
    HW spot 6 as in A. sulustris
    Male darkisk less reflective blue.
    Female UpF blue reaches tornal margin ,HW brownish blue reaches the margin.
    https://yutaka.it-n.jp/lyc4f/82160001.html
    see Otsuka L207 for female.


    A. normani .
    UnF spot 9 slightly dislocated.
    UnH spot 6 with the side margins straighter.
    Male upperside darker blue than A. sublustris.
    Female as in A. sublustris.
    https://yutaka.it-n.jp/lyc4f/82140001.html
    Otsuka L212.


    If you don't have Otsuka you can get a free download.

    It looks a perfect match.

    Hi Dr Seow,

    could the following skipper be Pelopidas assamensis?

    It was way larger than P. mathias and P. agna; roughly 1.5x P. conjuncta with large FW spots.

    Thank you!
