Figure 6. Distribution of adhesive setae in spiders.

Above: proportions of species bearing claw tufts, scopulae (incl. ‘false’ claw tufts), both or none, combined with lifestyle. Tree and plots below indicate proportions among the different lineages, with sizes of first plots resembling the number of species (numbers given in italic font). Results show the two major evolutionary pathways of spiders, web builders and free hunters, out of which the latter ones are often associated with adhesive setae.
