Fig. 9 in Courtship and male-male interaction behaviour of Orsima ichneumon (Simon, 1901), an ant-mimicking jumper spider (Arachnida: Salticidae)

Fig. 9. Mount behaviour and copulation (a) Male uses legs I and II to tap female's legs I and II, female assumes hunched legs and lowers cephalothorax to substrate with abdomen tilted higher than cephalothorax, allowing male to walk over her cephalothorax; (b) Male moves to left or right of female's abdomen; (c) Female's abdomen is rotated 30–60° for male to insert palp and copulation occurs.
