Ultrastructure of Egg Chorion and Its Sculpture in Two Arctiids (Erebidae: Arctiinae)

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