Delta pyriforme philippinense
Black wasp about 1 inch long with club-shaped petiole connecting abdomen and thorax. Amber-colored wings, antennae and ventral side of abdomen.
Suburban neighborhood on mesic, tropical, insular lowland plateau.
Spotted on concrete slab outside my back door, apparently in distress. It did not fly away when I approached, but walked slowly. However, after I took my camera inside and returned to look for it, it was gone, so it obviously had more mobility than it seemed when I first observed it. A couple of days after I made this spotting I discovered the dead insect a few yards away. I collected the corpse and recorded additional images (nos. 3-5).
