    • Abstract

       

      Eggs of Triatominae and Echtrichodiinae, though identical, present distinct ultrastructural diversities in respect of collar rim, follicular pattern, position and distribution of the aero-micropylar system and the operculum, facilitating easy identification of the eggs of the species of the subfamilies. Possessing as they do, a continuous endochorionic aerostatic layer for supplying ambient oxygen to the developing embryos, they simulate other reduviid eggs. While the eggs of Triatominae are comparatively simple, being laid in exposed habitats, those of Echtrichodiinae possess additional opercular respiratory structures in view of their oviposition in specialised habitats.
