Identification

Pagasa are distinguished from other Nabidae by the presence of a fossa spongiosa—a specialized pad of hairs on the tip of the front tibia that aids in climbing slick surfaces and grasping prey. They can be fully winged or have wings reduced to non-functional pads. The of the front leg is muscular and swollen, armed with teeth on the underside for securing prey. Some species appear almost -like in form, leading to potential confusion with ground beetles (Carabidae).
