Cellar spider or Daddy longlegs

Pholcus phalangioides

Description:

Is a spider of the family Pholcidae. Females have a body length of about 9 mm; males are slightly smaller. Its legs are about 5 or 6 times the length of its body (reaching up to 7 cm of leg span in females). Its habit of living on the ceilings of rooms, caves, garages or cellars gives rise to one of its common names. In Australian homes, they are considered beneficial because it is sometimes believed they will kill and eat the venomous Redback spider.

An urban legend states that Pholcidae are the most venomous spiders in the world, but because their fangs are unable to penetrate human skin, they are harmless to humans. These claims have both been proven untrue. Recent research has shown that pholcid venom has a relatively weak effect on insects. In the MythBusters episode "Daddy Long-Legs" it was shown that the spider's fangs (0.25mm) could penetrate human skin (0.1mm) but that only a very mild burning feeling was felt for a few seconds. :D
