Abstract
Assessment of butterfly biodiversity at different habitat type s of Gozamen woreda, Amhara regional state, Ethiopia, studied from mid-June 2021 to mid-July 2021. There were 44 butterfly species from five families, with a total of 1023 individuals identified. The Nymphalidae family had the most diversity, while the Papilonidae and Hespariidae families had the least diversity. The diversity and abundance of butterflies reported at Gozamen woreda varied between the forest habitat and the mosaic habitat. The largest diversity and abundance of butterflies were found in the forest habitat, with 41 species and 680 individuals, and the lowest were found in the mosaic habitat, with 22 species and 343 individuals. The Simpson diversity indices were higher in the forest habitat (0.96) than in the mosaic habitat (0.94). The evenness index of butterflies was higher in the forest habitat (3.5) than in the mosaic habitat (3.0). The evenness and equitability index were highest in the mosaic habitat, with 0.88 and 0.96 respectively. The diversity and abundance of butterflies were significant, with Іж² = 10.43 and p = 0.001. The Jaccarda index of similarity revealed that forest habitat and mosaic habitat were 43.2% similar. Accumulation curves for mosaic habitat and forest habitat showed an increase until the 200th and 300th individuals were captured.
