Abstract
Eggs of Megaselia spiracularis and M. scalaris were examined with the aid of scanning electron microscope. The surface structure of the eggs of both species was observed, and some new findings were made. The micropylar region, which was not noticed so far by light microscope, was recognized as a kind of cactus form situated at the anterior end of the egg. The markings of ventral surface, which were not elucidated clearly by light microscope, were observed in detail in both species.
