Whereas most animal and some dioecious plant species have an XY or X0 system, relatively few share the WZ or Z0 system with Lepidoptera, the most prominent ones being birds, snakes, and caddis flies (Trichoptera). This chapter focuses on the fate of the W chromosome. Although most extant lepidopteran species possess a W chromosome, the Lepidoptera clade started evolution with a Z0 system, and the W chromosome appeared much later in its history. Thereafter, the evolution of the W chromosome followed the rules already learned from Y chromosomes: It decayed, fused with other chromosomes, and sometimes even got lost again. Hence, the W chromosome exhibits the full evolutionary life cycle of a typical sex chromosome in a single clade. Here we review data on the composition of W chromosomes, their molecular differentiation and evolution, and their role in sex determination.
