Standard accounts of how spiders obtain food without masticating their prey are probably largely wrong. Species in the families Uloboridae, Thomisidae, Araneidae and Theridiidae do not inject digestive fluid into the prey’s ...

Theridion evexum constructs webs in the understory of wet middle-elevation forests in Costa Rica. The spiders construct retreats by curling a leaf and produce a mesh in front of the opening. Long, more or less vertical ...

We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...

We describe the presence and dimensions of viscid globules in both the sheet and tangle portions of the webs of Achaearanea tesselata (Keyserling 1884). We found viscid globules in all sheets and tangles of the webs examined. ...

Adult females of Helvibis longicauda accumulated tiny pieces of vegetation in the mesh of their webs. The amount of debris accumulated was much greater in webs of spiders with either egg sacs, spiderlings or juveniles than ...

Adaptive flexibility in response to environmental variation is often advantageous and occurs in many types of traits in many species. Although the basic designs of the orb webs of a given species are relatively uniform, ...

Web designs of young spiders are often less derived than those of older conspecific individuals. This study tested whether this ‘‘ontogeny repeats phylogeny’’ pattern occurs in two species of Latrodectus and two species ...

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 ...

The abundance of wood cavities is thought to be a limiting factor for bird species that depend on these cavities for nesting. Thus, it is expected that number of cavity adopters correlates with number of cavity excavators ...

Las tasas de parasitismo de Theridion evexum por la avispa parasitoide Zatypota petronae y de Allocyclosa bifurca por Polysphincta gutfreundi fueron estudiadas durante dos años. El parasitismo en T. evexum fue muy bajo ...
