Construction and function of the web of Tidarren sisyphoides (Araneae: Theridiidae)

Madrigal Brenes, Ruth; Barrantes Montero, Gilbert (2009)

In this paper, we describe the construction and function of the double sheet and tangle web of Tidarren sisyphoides (Walckenaer 1842). Web construction includes several stages: construction of the scaffolding that serves ...
Ontogenetic changes in web architecture and growth rate of Tengella radiata(Araneae, Tengellidae)

Madrigal Brenes, Ruth; Barrantes Montero, Gilbert (2008)

In some spiders features of the webs of early instars may represent features of the ancestor's web. Some second instar spiderlings (first instar outside of the egg sac) of Tengella radiata (Kulczynski 1909) construct a ...
Vestiges of an orb-weaving ancestor? The “biogenetic law” and ontogenetic changes in the webs and building behavior of the black widow spider Latrodectus geometricus (Araneae Theridiidae)

Eberhard Chabtree, William G.; Barrantes Montero, Gilbert; Madrigal Brenes, Ruth (2008)

Young juveniles of L. geometricus fit the strong trend for “ontogeny to repeat phylogeny” previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur ...
