The identification of moths has been always dependent on characters like wing maculation, wing venation, male and female genitalic features, but the ultrastructural characters like egg chorion patterns have been completely ignored. These are equally important for identification. In the present study, scanning electron microscope was used to inspect, characterize, and depict eggs of two tiger moth species i.e., Andala unifascia Walker, 1855 and Creatonotos transiens (Walker, 1855) referable to family Erebidae. On the eggshells of both these species, morphological features have been observed and these are of great taxonomic value at species as well as at genus levels. These characters will enable identifying moths at much earlier stages of their life histories i.e., eggs.
