However, in the unlikely event of a bite from this species, a positive identification of the spider by an expert should be made and medical attention sought if any reaction persists for more than a short time. Most reputable sources, including the University of California, Riverside, still say that this species would never be considered as harmful to humans. Recently, however, it was shown that the tiny fangs (about 0.25 mm) were actually capable of piercing human skin in a test done on the US television show, Mythbusters, but the stinging sensation produced was very short-lived. They have long and skinny legs and a peanut-shaped body that sets them apart. It had been thought that the fangs of this spider were incapable of piercing human skin. Long-bodied cellar spiders (Pholcus phalangioides), are not only mistaken for brown recluses, theyre also mistaken for harvestmen or daddy long-leg spiders. However, the venom is not actually that potent, even for insects. The myth probably grew from observations that the Daddy-long-legs Spider will kill and eat a Redback Spider.

While both have long legs, there are some distinctions that set them apart, leading to confusion surrounding their classification.

However, there is no scientific evidence to back this up. Daddy long legs, often considered spiders, belong to two different groups of arachnids: pholcid spiders and harvestmen. cellar spider, Holocnemus pluchei, is now established throughout the United States, especially in the Southwest. There is a persistent belief that the Daddy-long-legs Spider has the most toxic venom of all spiders.
