Spider samples were taken after planting the rice crop until harvesting at 15 days interval (DAT)... more Spider samples were taken after planting the rice crop until harvesting at 15 days interval (DAT) at randomly selected 8 sites in four districts (Kushinagar, Deoria, Gorakhpur and Mahrajganj) of northeastern Uttar Pradesh, India. A total of 13,303 individuals belonging to 58 species, 28 genera and 10 families were collected. Among them, 9 (53.3%), 11 (33.6%), 35 (12.8%), and 3 (0.3%) species were most dominant, dominant, agrophile and rare, respectively. The most dominant species was Tetragnatha javana (7.23%) followed by Pardosa pseudoannulata (6.89%); Tetragnatha mandibulata (6.34%); Pardosa birmanica (6.33%); Hippasa holmerae (5.70%); Tetragnatha maxillosa (5.46%); Oxyopes javanus (5.31%); Hippasa partita (5.05%); and Camaricus formosus (4.95%), Araneus ellipticus (4.89%), Clubiona japonicola (4.43%), Leucauge decorata (4.19%), Neoscona theisi (3.88%), Lycosa mackenziei (3.86%), Plexippus paykulli (3.00%), Plexippus calcutaensis (2.52%), Plexippus petersi (2.01%), Leucauge celebesiana (1.99%), Pardosa sumatrana (1.58%), and an araneid species (1.29%). Of the total catch, 30.9% were juveniles and proportion of males was 0.72. Lycosidae and Tetragnathidae accounted for the largest population, each representing 29.85% and 27.95%, respectively. Among six foraging guilds, orb weabers (44.3%) formed the most dominant guild followed by ground runners (30.0%), stalkers (15.2%), foliage runners (5.3%), ambusers (5.1%) and space builder (0.1%). Different ecological indices were calculated at all 8 locations and 8 DATs and its consequences were discussed.
