Abstrakt: Sex chromosome evolution is a fascinating and very dynamic process, which is best to be studied on diverse groups of organisms. Moths and butterflies (Lepidoptera) are known for their species diversity and female heterogamety, which makes them an ideal research model. Most species of Lepidoptera have a WZ/ZZ (female/male) system, although some species lack the W chromosome. The first part of this thesis discusses possible mechanisms and points of its origin in terms of phylogeny. Specifically, it focuses on the lack of W chromosome in the group of bagworms (Psychidae), supporting recent theory about the independent origin of W chromosomes in Lepidoptera. The second part of the thesis provides valuable information about the W chromosome variability and molecular content within the group of loopers (Geometridae). Finally, the third part describes the accumulation of retrotransposons on the W chromosome in Peribatodes rhomboidaria and emphasizes their importance in the process of sex chromosome differentiation.
