    Default Arhopala trogon

    I last shot this species in 2009 along MNT, and have failed to encounter it again at the same location ever since. Today, I was pleasantly surprised when I ran into one in another part of the nature reserve, miles away from MNT.

    Hi,
    I believe I also saw one today. DSC04708.JPG. Am I right?

    Cheers,

    Thanks. It is only a matter of time you run into one.

    May be. A few spots are not there or misaligned, likely a result of aberration or birth defect.

    Oh. The forewing band looks very different from yours. Spots are very small.

    Does anyone else have an opinion on the ID of this aberrant looking trogon?

    thanks for advice,

    Yik's shot does not seem to have the purple wash that A. trogon​ normally has.

    According to the key & text of C&P4 , the underside is hair brown without a purple wash so this is definitely A. aurea, otherwise these two are near identical.

    My photo was taken without flash. Would the purple wash be obvious to the eye, or is the color only accentuated with flash? I looked at a friend's copy of Fleming, and the trogon there looked brown.

    Oops here. It is A. trogon.
    I have actually thought it was A. trogon much earlier when comparing the spots but got sidetracked with the purple wash feature later.
    You raised a very pertinent point here.
    Note without the flash the underside is quite purplebrown.

    An important clue to the ID of A. trogon is that the two black spots in space 1a(tornal angle) & space 2 are quite large.
    In A. aurea they are somewhat flattened.

    The male A. aurea is also slightly purple-shaded, but without the strong glaze very apparent with flash in trogon.

    Apart from the more prominent black spots the markings of A. trogon tend to be broader.

    Thanks Dr Seow. Now that you mentioned it, the relative prominence of the black spots suddenly becomes quite obvious!
