Long-bodied Cellar Spider (Pholcus sp. considered most likely to be P. phalangioides)
A long ago introduced species (=alien) spider of the family Pholcidae now widely distributed in North America. Females have a body length of about 8 mm and males are slightly smaller. The length of its legs are about 5 or 6 times the length of its body (reaching a legspan up to 7 cm in females).
Confusion often arises over its common name, because “daddy long-legs” is also applied to two other distantly related but superficially similar arthropods. Nor it is a “harvestman”
Frequently seen living on the ceilings of rooms, caves, garages or cellars. This spider species is considered beneficial in parts of the world because it kills and eats other spiders.
