Webbprothoracic legs (Figures 1(a) and 2(b)). The sac containing the attached paired glands is inverted and contracted back into the thoracic hemocoele by a pair of retractor muscles (Figure 2,Rp1). Both types of glands are found in all larval instars, and apparently show negligible changes in shape during ontogeny.

His metathoracic (rear) legs will grasp onto the lower (ventral) portion of the female. Often his legs overlap crosswise.
Webb1 juli 1991 · The prothoracic leg’s horizontal force pattern was different from that seen in the foreleg of a trotting quadruped, such as a dog, despite the fact that whole-body ground reaction force patterns can be similar in six- and four-legged runners (Alexander, 1977a; Full and Tu, 1990, 1991).
