Species composition and diversity of ant fauna (Hymenoptera: Formicidae) observed throughout a Yala season growing cycle of paddy fields in Gampaha District, Sri Lanka

Rice fields are inhabited by a great variety of fauna including ants. Species composition, proportional abundance and species diversity of ant fauna in two, similar rice fields in Mahadarawa, Gampaha District of Sri Lanka were investigated by honey baiting, hand collection and pitfall trapping condu...
