    Moths are just way too difficult.
    I dont have the proper references to ID many of them.
    There are several thousand species in Singapore alone.

    However these Zygaenid moths are fascinating & I think I have their IDs.

    1. Boradiopsis harmani.
    There appear to be two species in our region.
    The 2nd B. bipartita is not recorded from Singapore.


    They are both very similar.

    B. harmani Open plain area larger; FW marginal spots extend from apex down to the tornus (lower angle of the FW.)
    B. bipartita; Open area smaller; FW marginal spots end about 1/3 from bottom.

    2. Very likely Heteropan scintillans. Range India to Sundaland.
    Pale grey with a dark margin & a powderly bluish iridescence.
    In the image below the FWs are folded well in exposing the margins of the HWs.
    Sri Lanka.

    3. Very likely Phacusa tenebrosa. Range India to S.E. Asia. Correction: Phacusa crawfurdi.
    The spots match very well, including the broad brown lower marginal area.
    The body is marked with thin gold lines.

    Thyrassia species.
    FW markings differ; Abdomen more gold banded.
    Taxa penangae & refflesi are considered separate species.
