The ultimate leaf masquerade in an orb web spider, an undescribed species of Poltys (Araneidae) from Yunnan. A–C, A female had hung dead leaves from a twig that also included live leaves to masquerade itself from visual predators (A). Upon slight disturbance, she withdrew higher onto the twig (B, C) where it remained motionless; D, lateral view of female pose in nature, note her abdomen resembling a dead leaf ventrally and a live, green leaf dorsally, both parts extending into a long and straight, apical abdominal hairy pedicel; E, female placed on a flat surface, showing her flexible abdominal pedicel, now curved; F, same, dorsal close up, note ''leaf venation'' and long hairy pedicel.
