A Brief Introduction:
Thubana deltaspis represents one of the three Thubana species distributed in Taiwan and doesn't share similar wing pattern with the other two. T. microcera which is not recorded in Taiwan, has very similar wing pattern with T. deltaspis: dark ground colour and an white triangular marking along anterior margin of forewing. However, the head of T. deltaspis is brown while T. microcera is ochreous white.
