The study aimed to investigate the seasonal presence and characterization of the group of butterflies (abundance, richness and biodiversity) in the agroecosystem of Brassicaceae plants in the Basra province. Two different ecosystem sites (Karmat Ali at the sedimentary habitat and Al-Zubair region at the desert habitat) were sampled during the growing season of 2020/2021. There are 823 and 507 individuals at the Karmat Ali and Al-Zubair sites, respectively; the specimens consist of 9 butterflies belonging to four families. The most abundant family was Nymphalidae (60%), followed by Lycainidae (28%) and Pieridae (9%), while Hesperiidae recorded the lowest relative abundance of 3%. The highest butterfly population was recorded for Vanessa Carudi, while Pieris rapae had the lowest density. The results showed differences in abundance, species richness, and Diversity of butterflies at the sites. The highest values of Diversity and richness were at Karmat Ali, compared to the Al-Zubair region. The study of butterflies' abundance and biodiversity indices indicated that environmental factors and the polyculture plantations support the butterfly population in agricultural habitats.
