Lepidoptera: Biology and Taxonomy

The structure of the eggshells and particularly the morphogenesis and the fine structure of an aeropyle were studied in the wax moth Galleria mellonella. Galleria has eggs whose chorion shows an inner trabecular layer and the walls of aeropyles are coated by threads. During oviposition air enters the trabecular layer in a sufficient quantity to allow the development of the caterpillar if the egg is immersed in boiled water or paraffin oil. This layer is in communication with the atmosphere by means of 150 to 200 aeropyles.
