With a body length ranging up to nearly half an inch. These things are, let’s admit, a bit creepy both in appearance and in habits. The white tip at the rare of spider abdomen is visible. The long-bodied cellar spider, Pholcus phalangioides. If these spiders were indeed deadly poisonous but couldn't bite humans, then the only way we would know that they are poisonous is by milking them and injecting the venom into humans.Ī photo of a Pholcus phalangioides that has immobilises a whitetail spider (Lampona cylindrata) by wrapping it in silk.Ī whitetail spider (Lampona murina) wrapped in silk. ![]() There is no reference to any pholcid spider biting a human and causing any detrimental reaction. If you are bitten by a cellar spider, seek medical attention immediately. ![]() It can cause redness and swelling around the bite site. The cellar spider’s bite generally causes only minor symptoms, but in some cases, it can lead to more serious reactions. The myth is incorrect at least in making claims that have no basis in known facts. The vast majority of cellar spider bites cause only minor symptoms that are mild and short-lived. There is an often-repeated urban myth that states ‘the daddy longlegs is the most poisonous spider in the world, but it can’t bite you because its fangs are too small’. When a victim is trapped in the web it immobilises it by wrapping it in silk, not like other spiders that use venom. These webs are constructed in dark and damp recesses, in caves, under rocks and loose bark, abandoned mammal burrows in undisturbed areas in buildings and cellars, hence the common name "cellar spiders". However, Pholcids are also quite commonly found in warm, dry places, such as household windows. Pholcid spiders (Araneae: Pholcidae), officially cellar spiders but popularly known as daddy long-legs, are renown for the potential of deadly toxic venom, even though venom composition and potency has never formally been studied. They hang inverted in messy, irregular, tangled webs. Pholcids are fragile spiders, the slender body being 2–10 mm in length with very long legs which may be up to 50 mm long. Pholcids are web-weaving spiders and are distributed worldwide and were accidentally introduced to New Zealand. The Daddy long legs are an introduced spider during the early European colonial period. Clever cellar spiders have been known to vibrate other spiders’ webs, mimicking trapped prey to lure the hosts into their devious traps, including huntsman spiders and poisonous hobo spiders.Common Name: Daddy Long Legs, Granddaddy long-legs spider, Daddy long-legs spider, Daddy long-legger, Cellar spider, Vibrating spider, Daddy longlegs spider. Some cellar spider species raid other spiders’ webs and eat the hosts, their eggs or the other spiders’ prey. ![]() This erratic behavior earned these spiders the name, "vibrating spiders," although they are not the only species to exhibit this behavior. When cellar spiders’ webs are disturbed or these spiders are threatened by entangled, large preys, these arachnids initiate rapidly vibrating, gyrating motions in their webs, blurring themselves, making it difficult to focus on them. Cellar spiders may eat prey immediately or store their catches for later. After snaring prey, cellar spiders quickly envelop their prey with silk then inflict fatal bites. Preferring the dark, damp recesses of caves, under rocks, under loose bark, abandoned mammal burrows, in addition to undisturbed areas such as cellars and basements, cellar spiders also spin their webs in warm, dry windows and attics.Īlthough cellar spider webs don’t contain adhesive properties, their random web structure traps insects, making their escapes difficult. Confusion arises due to applying the name "daddy longlegs" to two distantly related arthropod groups: harvestmen, which are arachnids but not spiders, and crane flies, which are insects.Ĭellar spiders hang upside-down in messy, irregular, tangled webs. Often mistaken for other spider species, cellar spiders are commonly called daddy longlegs spiders, granddaddy longlegs spiders, carpenter spiders or vibrating spiders.
