After more than a decade of research, Professor of Biology Greta Binford and Research Associate and Visiting Professor Pamela Zobel-Thropp have discovered for the first time what is in the venom of these animals, and compiled evidence of the effects of their venoms on humans. The new evidence crushes that old urban legend. In a new research paper, "Not So Dangerous After All," just published in the journal Frontiers in Evolution and Ecology , Binford and Zobel-Thropp detail their chemical analysis of pholcid commonly known as cellar spiders or daddy long-legs venom. Their results show that the venom is full of interesting proteins and peptides and is highly toxic to insects, but all evidence indicates it has negligible toxicity on mammals especially when compared with black widow venom, for example. In , Discover Network's hit series MythBusters took the liberty of dispelling the daddy long-legs myth with venom from the same species and overseen by Chuck Kristensen, a coauthor on this work; however, until Binford's paper was published, there had been no rigorous analysis of what is in the venom of any pholcid spiders. Funded by a grant from the National Institutes of Health since , the paper details the team's diligent pursuit of solid evidence.

Long Leg Definition

Daddy longlegs , order Opiliones , also spelled daddy-longlegs or daddy long legs , also called harvestman , any of more than 6, species of arachnids class Arachnida that are known for their extremely long and thin legs and for their compact bodies. Daddy longlegs are closely related to scorpions order Scorpiones but, because of their appearance, are often mistaken as spiders order Araneida or Araneae. However, unlike true spiders, in which the body is divided into two distinct segments the cephalothorax and the abdomen , daddy longlegs look as though they have only one segment, because of a broad fusion that makes the juncture between the two segments almost indiscernible. Many species of daddy longlegs are omnivorous, feeding on small insects , mites , spiders, snails , and vegetable matter. Food generally is obtained through predation or scavenging. A fifth, extinct suborder, Tetrophthalmi, is indicated by fossil specimens.

Don't fear the pholcid: Daddy long-legs' venom is only dangerous if you're an insect

A long leg is part of a spread or combination strategy that involves taking two positions simultaneously to generate a profit. Long leg investments can be used in a wide range of spread and combination scenarios. Generally, a long leg position is entered with a simultaneous short leg position.

Pholcidae , commonly known as cellar spiders , daddy long-legs spider , granddaddy long-legs spider , carpenter spider , daddy long-legger , vibrating spider and skull spider , is a family of araneomorph spiders first described by Carl Ludwig Koch in The common name "daddy long-legs" is used for several species, especially Pholcus phalangioides , but is also the common name for several other arthropod groups, including harvestmen , which are arachnids but not spiders, and crane flies. Pholcids are thin and fragile arachnids. Pholcus and Smeringopus have cylindrical abdomens and eyes arranged in two lateral groups of three and two smaller median contiguous eyes.
