Objective To study morphologically the eggs of T. circummaculata and T. rubrovaria. Methods Ferry eggs of the two species were measured through Nikon model 6C profile projector Student test was utilized for the statistical analysis and scanning electron microscopy for the morphological study of the eggs. Results/Conclusions The statistical analysis shows that the T. rubrovaria eggs are larger that those of T. circummaculata. Microscopical observations revealed that the chorial rim and the spermatic groove are less evident in T. circummaculata than in T. rubrovaria. Both species, the majority of exochorion cells are hexagonal. It was also observed the embryo eclosion and details of the embryonic molt.
