    Default Neptis species

    In my photo collection there are a number of Neptis specimen from Sri Lanka, Thailand and Vietnam that I tentatively labeled as Neptis hylas.
    However, I doubt if they are all correctly identified, in particular the one (no. 4) seen in Vietnam.
    Would very much appreciate your opinion.

    1. Neptis hylas?

    The 3 species in which the FW cell bar has a fracture line or is broken are Neptis hylas ,N. sappho & Phaedyma columella.

    P. collumella may be ID'ed by the FW spot on the lower margin(dorsum) being large with a small spot above it (in space 1b).

    Neptis hylas & sappho are very similar & confusing.


    Neptis sappho :FW with the four postdiscal spots narrower & more rounded in particular spot 1b is always rounded.
    On the underside FW N sappho have the veins black but this is difficult to see in the field shot & unreliable.
    N. sappho is widespread in subtropical & temperate regions , into southern Europe.

    Neptis hylas; FW with the four postdiscal spots rather wide (ie horizontally elongate) FW spot 1b oblong or oval.
    Underside FW with veins not black but hard to judge.
    Sri Lanka.

    All your shots are correctly Neptis hylas.
