MYTH BUSTER ... "Stop the Urban Legend!"
Is the “Daddy Long-Legs” the most venomous spider? NO...Absolutely Not
There are 2 groups of Arachnids commonly called "Daddy Long-legs" & neither are dangerous to people.
ARACHNIDA: Opiliones (syn. Phalangida)
Commonly called "Harvestmen" or "Daddy Long-legs," Opiliones DO NOT POSSESS VEMON nor a delivery system.
ARACHNIDA: Araneae (True Spiders)
Family: Pholcidae, "Cellar Spiders"
Although these are "true spiders," their venom is mild and not considered dangerous to vertebrates (incl. humans).
