ResumoThe objective of this work was to evaluate the influence of seasonality on the diversity and richness of the edaphic macrofauna during the dry and rainy periods, in an area of Caatinga in the Brazilian semiarid region. Samples were collected in a sample grid, totaling 10 points, spaced 30 meters apart, in rainy and dry seasons. For quantitative assessment of macrofauna, the total number of organisms (species abundance) was measured, according to diversity. The diversity of the soil macrofauna for this research corresponds to the following order: Hymenoptera> Diptera> Aranaea> Orthoptera> Coleoptera, for the rainy and dry periods, with a greater predominance of the order Hymenoptera. The influence of seasonality was observed in relation to the richness and diversity of the region's macrofauna, with marked fluctuations between the rainy and dry periods.
