Abstract

The milkweed bug, Spilostethus pandurus egg was re-described and photographed using
light and scanning electron microscopes. Egg whole-mount showed the different development
stages from zero to 116 hrs. Egg dechorionation was unfeasible at the early
stages, from 0-100 hrs. SEM showed the hatching lines and weakness lines, and chorion
with 11-13 micropylar openings.
