The Pholcidae are a family of araneomorph spiders. The family contains over 1,800 species, including daddy long-legs spiders. Some species of pholcids exhibit a threat response when disturbed by a touch to the web or entangled large prey. The arachnid responds by vibrating rapidly in a gyrating motion in its web. This behavior has led to these spiders sometimes being called ‘vibrating spiders’
About Pholcidae in brief
The Pholcidae are a family of araneomorph spiders. The family contains over 1,800 species, including daddy long-legs spiders. They are found in every continent in the world except Antarctica. Some species of pholcids exhibit a threat response when disturbed by a touch to the web or entangled large prey. The arachnid responds by vibrating rapidly in a gyrating motion in its web. This behavior has led to these spiders sometimes being called ‘vibrating spiders’ There is a legend that daddy. long-legged spiders have the most potent venom but that their fangs are either. too small or too weak to puncture human skin; repeated of the same harvest, harvest the same skin; or that they have a.
short fang structure but are able to deliver medically significant bites. According to Rick Vetter of the University of Riverside, California, daddy daddy spiders, possessing stronger fang muscles for penetration, are not toxic to humans. Pholcus phalangioides often uses an alternating tetrapod gait, which is commonly found in many spider species. The spider vibrates the web of other spiders, mimicking the struggle of trapped prey to lure the host closer. In some regions of the U.S. Brown recluse spiders also have uncate fang structures but are not as venomous.
