Biological material was collected using Barber pitfall traps, a passive and efficient technique for monitoring ground-dwelling fauna. Samples were collected at regular intervals of 12–16 days, and the captured material was subsequently preserved in 40% ethanol and taxonomically identified based on specialized literature and online resources. To characterize community diversity, the Shannon, Simpson, and Pielou’s Evenness indices were calculated. The results revealed significant differences between the two years, reflecting the influence of climatic conditions on faunal dynamics. In 2023, the community was dominated by Coleoptera (1,048 individuals), followed by Hymenoptera and Orthoptera, indicating a diversified and relatively stable structure. In 2024, the total abundance of Coleoptera decreased significantly (702 individuals), while Diptera showed a marked increase (425 individuals), becoming the second most abundant group. This shift reflects the differential response of taxonomic groups to the warmer and drier conditions observed in 2024, which favored water-tolerant and generalist species. Analysis of diversity indices indicated a reduction in both diversity and evenness in 2024, associated with a more uneven distribution of abundances. The study highlights the sensitivity of ground-dwelling arthropod communities to interannual climatic variability and underscores the importance of continuous monitoring for understanding ecological dynamics in agroecosystemsEnglishpea cropdwelling faunabiodiversity indicesArticle2069-8275
