The embryonic membrane of the stinkbug Plautia crossota is not a bag-like structure enclosing the embryo. It has the same shape as the embryo and covers the legs, proboscis etc. of the embryo like a skin. In other words, a larval stinkbug undergoes molting at the same time as hatching. At hatching, the proboscis which was previously stored in the head and thorax of the embryo, is pulled up into the snout region, and molting is completed upon the molting of the proboscis. The embryonic membrane (or exuviae ) with the egg burstor on its surface is left behind in the egg as the larva hatch (embryonic emergence). The video captured a series of these processes. A part of the video is played at fast speed to provide a better viewing of the changes
