Some have long legs, but others have short legs and look more like chunky mites. One of the major physical differences is that harvestmen do not have a defined “waist” like a spider. Harvestmen are arachnids – they have eight legs – but they are not spiders. The truth is that they do not tackle such dangerous prey head-on, rather, they cast lengths of silk to entangle such prey from a safe distance. A bite can be unpleasant, but the effects are short-lived.Ĭellar spiders have been known to capture and consume dangerous spiders like black widows, which may have led to the belief that they must be highly venomous in order to take on venomous prey. Is it because their mouthparts are too small to pierce human skin? Despite their small fangs, they are capable of puncturing human skin. There are no documented cases of human harm and no evidence to suggest they are dangerous to humans. So, are cellar spiders extremely venomous? The answer is no, their venom is relatively weak even on its intended prey. The vast majority of spiders are venomous, but only a few species have venom potent enough to harm humans. There are roughly 1,500 species of cellar spider, so who knows which one was claimed to be dangerous. These spiders are responsible for most of the cobwebs that we see in warehouses and garages. They will run or drop from their webs if pestered further. While unsettling to behold, this behavior might make it difficult for a predator to focus in on the spider. When disturbed, they often vibrate quickly in their webs, becoming a fast-moving blur. Their abdomens may be round, sausage-shaped, or peanut-shaped. Cellar spidersĬellar spiders, or cellar door spiders, are frail spiders with freakishly long and thread-like legs. To complicate the matter, three different leggy beasts are called daddy long legs or granddaddy long legs – so which one was supposedly claimed to be dangerous? Let’s explore each critter and determine if there is any truth to this claim. Have you heard that the “daddy long legs” is extremely venomous? Have you also heard that the only thing keeping this creature from terrorizing all of humanity is its tiny mouthparts that are unable to pierce human skin?
