Daddy long-legs

Fact Box
Pholcus phalangioides (RM)
Body length:
female: 8 mm
male: 7.5 mm
In a thin, tangled web attached to the ceilings and upper walls of rooms, sheds and caves (hence this species is also called a cellar spider) but also under bridges and in hollows of dead trees
Probably too small to cause illness in humans; the suggestion it has very potent venom is a myth but its long legs give it an advantage over other kinds of spiders
