Abstract :In this study, spermatheca and eggs of Pyrrhocoris apterus insert ignore into journalissuearticles values(Heteroptera: Pyrrhocoridae were examined by light microscope and SEM. The eggs have ~1.30 mm length and 0.94 mm width. Newly laid eggs turn from white to yellow as soon as embryonic differentiation. P. apterus egg surface shows polygonal insert ignore into journalissuearticles values(usually hexagonal and pentagonal); shapes. The eggs have pipe shaped 6-7 micropylar projections. The egg-burster which is a dark T-shaped or triangular pattern, explosive becomes visible when the embryo is well developed. The nimph, which has completed its embryonic development, comes out of the egg with peristaltic movements. The spermatheca of P. apterus consists of a bulb, a pump, a flange of pump, and duct. The morphology of the egg and spermatheca is useful for classification, because they show a great diversity among species and genera.
