Records from Sarmiento y Centenario

Other common names: Araña Patona, Araña De Las Casas.


Description: It has a somewhat elongated body and very long, thin legs, which is the most noticeable characteristic when differentiating it from spiders of other families. However, it shares this trait with other species of the Pholcidae family.

Sexual Dimorphism: Difficult to notice with the naked eye, but when observed closely, the modified pedipalps (mouthparts) of the male are visible, which serve a reproductive function. It is common to see females with their egg sac, which is circular in shape and not covered with silk, held by their chelicerae (mouthparts).

Habitat: Naturally inhabits caves and crevices, however, the species has adapted to living inside all kinds of human-made structures, both inhabited and abandoned, where it is a very abundant species.

Geographical Distribution: Cosmopolitan species, likely due to the involuntary transport of specimens by humans worldwide.

Behavior: It constructs an irregular and three-dimensional web, from which it hangs inverted. When disturbed, it performs a series of body vibrations, shaking rapidly from side to side as a defense mechanism.

Feeding: It is a sedentary species that consumes insects trapped in its web.
