Pholcus phalangioides, commonly known as the cosmopolitan cellar spider, long-bodied cellar spider or one of various types called a daddy long-legs spider, is a spider of the family Pholcidae. It is also known as the skull spider, since its cephalothorax is said to resemble a human skull. This is the only spider species described by the Swiss entomologist Johann Kaspar Füssli, who first recorded it in 1775.^[1] Its common name of "daddy long-legs" should not be confused with a different arachnid group with the same common name, the harvestman (Opiliones), or the crane flies of the superfamily Tipuloidea.

Females have a body length of about 8 mm while males tend to be slightly smaller. The length of the spider's legs are on average 5 or 6 times the length of its body.^[2] Pholcus phalangioides has a habit of living on the ceilings of rooms, caves, garages or cellars.

This spider species is considered beneficial in parts of the world because it preys on other spiders, including species considered dangerous such as redback spiders.^[3]^[4] Pholcus phalangioides is known to be harmless to humans and a potential for the medicinal use of their silk has been reported.^[5]^[6]^[7]
