Morphological phylogeny of cobweb spiders
and their relatives (Araneae, Araneoidea, Theridiidae).
As an example of the evolutionary intricacies that context dependency can unravel, we focus here on the evolution of a putative behavioral synapomorphy of cobweb spiders (Theridiidae): a typical attack tactic named reeling.
Hunting tactics in a cobweb spider (Araneae-Theridiidae) and the evolution of behavioral plasticity.
Wolf spiders (Lycosidae), cobweb spiders
(Theridiidae), and giant crab spiders (Sparassidae) showed no significant habitat preference.
Spiderlings also are predators once they begin to feed (Foelix 1996; GB unpublished data), although the young of some cobweb spiders (Theridiidae) are fed by their mother with freshly caught prey or by regurgitation (Gertsch 1949; Viera et al.
In these cobweb spiders, spiderlings cohabit with their mother in the same web, at least to the third molt outside of the egg sac (pers.
Asymmetric female genitalia and other remarkable morphology in a new genus of cobweb spiders (Theridiidae, Araneae) from Madagascar.
Theridiid or cobweb spiders of the granitic Seychelles islands (Araneae, Theridiidae).

The attack behavior of the cobweb spider
Achaearanea tesselata (Keyserling 1884) is roughly separated into three sequential steps: descend from the suspended retreat, pass through the sheet threads, and wrap the prey from underneath the sheet.
