It includes the cellar spider P. phalangioides, often called the "daddy longlegs".[2] This may cause confusion because the name "daddy longlegs" is also applied to two other unrelated arthropods: the harvestman and the crane fly.
Pholcus, like Pholcidae in general, have extremely long and thin legs.[3] The genus can be distinguished from other pholcid genera by its large size (body length >4 mm), eight eyes, evenly domed prosoma (lacking a median furrow or pit) and cylindrical opisthosoma (longer than it is high).[4]
In the wild, Pholcus live in environments such as caves, under rocks, forest shrubs and deep limestone cracks. Synanthropic species such as P. phalangioides live in and around buildings and other disturbed habitats.[5]
