The spiders inhabiting the ground surface of a citrus orchard were studied by using_fall traps for two years. A total of 912 specimens representing 29 species and eight families was collected. Nearly 86% of population was due to family Lycosidae alone. Three species viz. Pardosa birmanica (31.9%), Pardosa oakleyi (20.5%) and Lycosa vulgaris (2.8%) were the most dominant species which jointly constituted 74.2% of the total number of the spiders caught. The diversity index and species richness increased during the warmer months of the year while the evenness index value was low during these months.
