A crystalline layer has been identified as a constituent of the eggshell in the dipteran Drosophila melanogaster. This 400A thick intermediate chorionic layer (ICL) is composed of eight 50A thick sublayers and lies between the vitelline membrane and the endochorion. Whole mount views of isolated ICL after negative staining reveal P2 planar periodicity which, when analyzed further by optical diffraction and filtering, showed 1st (100A), 2nd, 3rd and 4th order reflections.
在双翅目果蝇的卵壳中，一种结晶层已被确定为其组成成分。这个厚度为400埃的中间绒毛膜层（ICL）由八个厚度为50埃的亚层组成，位于卵黄膜和内膜之间。负染色后分离出的ICL的整体观显示出P2平面周期性，通过光学衍射和滤波进一步分析时，显示出一阶（100埃）、二阶、三阶和四阶反射。
