Daddy Long-legs Spider

Pholcus phalangioides

The Daddy Long-legs Spider is a cosmopolitan species that is arguably the most common spider found inside Australian homes. It is perfectly adapted to indoor life and thrives in dark, undisturbed corners of houses, garages, and sheds. Recognised by its tiny body and extremely long, delicate legs, it constructs a loose, tangled web. Despite a persistent urban myth claiming it has the most potent venom of all spiders, its venom is weak and harmless to humans, and its fangs are incapable of piercing human skin effectively. It is generally considered a beneficial house guest, as it is a known predator of other, more dangerous spiders like Redbacks, as well as a consumer of common household insects.
