Jumper courtship is a complex business. Each species relies on its own suite of visual, tactile, and sometimes vibra tory and olfactory signals. The male usually sets out to impress a reluctant female, which is typically larger and relatively drab. A case in point: Asemonea tenuipes (far left, above). In the top panel a dark, narrow male resplendent in psy chedelic colors is on the underside of the leaf. The pale, plump female has escaped to the top. The male looks for her, and, feeling her movements through the leaf, he vibrates it, perhaps to telegraph his impending arrival (bottom panel). If she doesn't run away, he begins the mating dance, which seems sub missive, as if he were groveling (above). Finally, the female permits approach. The male rotates his body into a less awkward position and calms her with caresses from his out stretched legs (left, above). Looking under her abdomen, the male inserts his left palp (left, below) and discharges sperm. He can then mate again with his right palp.
