Fig. 8. Development of progranules (types I and II) into pigment granules of ommochromes (type III). Ommochromes are progressively deposited onto a homogeneous matrix of type I progranules (white spider), through an intermediate state of vesiculated progranules type II (light yellow spider). The progranules then decrease slightly in size and form the ommochrome pigment granules (type III) (bright yellow spider).
