    Default A Moth species from North Sumatra

    Dr Gabriella Fredriksson wrote to ask me about the ID of a moth species which has infested the forest there, and one which has attracted groups of orangutan to feast on them.

    The best I can do is to identify it as an Achaea species, but what is the species ID?

    I think it should be Achaea eusciasta.
    The FW discal mark is a black dot followed by a large oval/oblong spot.

    There are four widespread species of Achaea here which are very similar & can be pest.
    They are A. janata, serva eusciasta, & mercatoria.

    By comparing the cats of A. janata & serva , these two are very unlikely & can be ruled out.

    The adult of A. mercatoria can be recognised by the falcate forewing tip.

    This leaves Achaea eusciasta .

    Many thanks, Dr Seow for the detailed explanation on the deduction process.
    I have passed on the ID to Dr Gabriella Fredriksson.
