Figure 9 in The evolution of prey-wrapping behaviour in spiders
Figure 9. Ventral view of simultaneous wrapping movements of a mature female Azilia affinis wrapping a prey (stippled) (view from above the horizontal orb). First one (a) and then the other (b) leg IV pulled silk from the spinnerets, and then both legs were moved simultaneously ventrally (arrows in (c)) to press the line between them against the prey. The time elapsed between positions indicated by solid and dotted lines was 0.10 s (a), 0.10 s (b), and 0.03 s (c).
Figure 10 in The evolution of prey-wrapping behaviour in spiders
Figure 10. Hypotheses regarding the evolution of several prey-wrapping behavioural characters, including wrapping by moving the body versus moving legs IV, non-immobilization wrapping versus immobilization wrapping, alternate versus simultaneous movements of legs IV, and wrapping the prey by rotating it on the web line on which it was snared. The hypotheses are illustrated by super-position of the behaviour of the groups observed directly in this study or in previous publications (*) on a tentative phylogenetic tree (modified from Coddington 2005). Justifications of the hypotheses are discussed in the text.
Figure 8 in The evolution of prey-wrapping behaviour in spiders
Figure 8. Antero-lateral view of simultaneous wrapping movements of legs IV of a mature female Gaucelmus calidus. The spider first pulled sticky silk (with small black dots in drawing) from her spread spinnerets (second leg IV pulls line in dotted lines of (a)), and then moved both legs IV past the prey, snagging the sticky line between them on the prey (dotted lines in (b)). The time elapsed between positions indicated by solid and dotted lines was 0.1 s in both drawings.
Figure 7 in The evolution of prey-wrapping behaviour in spiders
Figure 7. Stages in simultaneous use of legs IV early attack behaviour by Nesticoides ruficeps on a muscoid fly. (a) The left leg IV pulled a segment of sticky wrapping line from the spinnerets (dotted black line). This leg then held the sticky line (solid lines in (b)) while the right leg IV pulled an additional length of sticky line, and then both legs IV swung ventrally and anteriorly to apply the sticky line to the prey (dotted lines in (b)). The time elapsed between positions indicated by solid and dotted lines was 0.03 s (a) and 0.07 s (b).
Figure 6 in The evolution of prey-wrapping behaviour in spiders
Figure 6. Early stages of an attack on a fly prey by Theridion evexum. (a) The spider tapped prey with her right leg I and quickly withdrew it. Then she turned to face away from the prey (b–e). She attached her drag line to the line along which she had been descending (b), and reached posteriorly with leg II to grasp the line above (b, c). She seized her drag line with her left leg III (c), and also brought her right leg IV to her spinnerets (c) to begin to pull what may have been the first segment of sticky wrapping line (c, d). She then pulled additional segments of wrapping line with her left leg IV (e) and right leg IV (f). Finally, she applied the line between the two legs IV to the prey with a simultaneous ventral movement of both legs IV (g) (small arrows show movement between positions indicated by the solid and dotted lines). The time elapsed between first and second positions was 0.27 s (a), 0.24 s (b), 0.12 s (c), 12 s (d), 0.12 s (e), 0.07 s (f), and 0.03 s (g).
Figure 1 in The evolution of prey-wrapping behaviour in spiders
Figure 1. Wrapping behaviour of Psalmopoeus reduncus (Theraphosidae). (a) Spider tilts her abdomen to the right as the right posterior spinneret is pressed to the substrate (position indicated by dotted lines followed other position by 0.10 s); (b) the spider presses both posterior spinnerets to the substrate; (c) the spider turns (arrow), swinging its abdomen toward the right while the leading spinneret is lowered and the trailing spinneret is raised; (d) wrapping lines emerging from the trailing, raised spinneret are visible; (e) wrapping lines emerging from the leading, lowered spinneret are visible.
Figure 5 in The evolution of prey-wrapping behaviour in spiders
Figure 5. (a, b) Portions of a Drosophila fly that had been wrapped by the pholcid Physocyclus globosus were covered with a film of apparently liquid, presumably gluey substance; (b) close-up.
Figure 3 in The evolution of prey-wrapping behaviour in spiders
Figure 3. Wrapping behaviour of Tengella radiata (Tengellidae) (a, b) and Tortolena sp. (c). (a) The trailing spinneret was raised (arrow) while the leading spinneret was lowered; (b) a pair of lines from the spinnerets (arrows) were visible; (c) the spider turns while standing over the prey (not shown), with the leading spinneret lowered and the trailing spinneret raised. The time elapsed between the positions indicated with solid and dashed lines was 0.50 s.
Figure 2 in The evolution of prey-wrapping behaviour in spiders
Figure 2. Patterns of attachments of wrapping lines by Psalmopoeus reduncus (a) and Tengella radiata (b, c) on and near the prey package (thick lines) (numbers refer to order in which attachments were made. (a) Zig-zag attachments by a P. reduncus in stage I, prior to turning above a prey (l, attachment by leading spinneret; b, attachment by both spinnerets; t, attachment by trailing spinneret); (b, c) attachments made by T. radiata on and near to different prey.
Figure 4 in The evolution of prey-wrapping behaviour in spiders
Figure 4. Wrapping behaviour by the filistatid Kukulcania hibernalis. (a, b) In lateral view, the spider pulls wrapping lines from the spinnerets with its left leg IV (a) and then pushes them toward the prey (b); (c, d) a lateral view of a similar sequence, but in which the spider's spread spinnerets are visible and its body is lifted about 90°; the right leg IV pushes silk toward the prey while the left leg IV withdraws from the prey and prepares to pull more wrapping silk from the spinnerets; (e, f) in a posterior view, the spider twists its abdomen toward the left leg IV (e) as this leg is brought near the spinnerets and begins to pull wrapping lines (f). The time elapsed between lines labelled 1, 2, and 3: 0.03 and 0.03 s (a), 0.03 and 0.10 s (b), 0.03 s (c), 0.03 and 0.17 s (d), 0.07 s (e), and 0.03 s (f).

Building behaviour does not drive rates of phenotypic evolution in spiders
<p>This data set contains raw data tables, scripts and supplemental figures supporting the article Wolff et al. (2021, PNAS 118: e2102693118). In our study we assembled morphometric and ecological trait data of spiders from literature and de novo measurements and observations and used this data to infer the rates of morphological change over deep time in relation to web building behaviour.</p>
