Definition

noun

A taxonomic family (in the order Araneae) whose member species are commonly called cellar spiders or daddy long-legs spider


Supplement

Pholicidae is a taxonomic family belonging to the order Araneae of class Arachnida. The members of this group are generally called cellar spiders or daddy long-legs spiders. The common name, daddy long-legs should not be confused to other arthrodpod groups that also go by the same name: the harvestment arachnids and the crane fly insects. The name accounts for the species' long legs, which could be about five to six times the length of the body.

There are about 1340 members of the Pholicidae family. Many of them can be found living in human habitats, e.g. in the corners, dark spaces, or cellars. Other common habitats include caves, mammal burrows, and under the rocks. Their body length may reach up to fifty mm. Many of them (particularly, Pholcus and Smeringopus) have a peanut-shape body and a globular or cylindrical abdomen. Their color may be brown or gray.

One of the most common species found in human habitats is the Pholcus phalangioides.
