Short-bodied cellar spiders, on the other hand, have legs that are about ½ inch long. The legs of long-bodied cellar spiders can be up to two inches long. The legs of cellar spiders are particularly long and thin, giving them their typical “daddy longlegs” appearance. At the rear of their abdomen are small, noticeable spinnerets that produce silk for constructing webs. Their cephalothorax is narrower, while the abdomen is typically more rounded. Head and BodyĬellar spiders, like all arachnids, have two body segments – the cephalothorax in the front and the abdomen in the back. Their color varies from pale yellow to light brown or gray. These spiders are also characterized by their slender, elongated bodies, which often appear cylindrical or pear-shaped. Their most distinguishing feature is their long, thin legs, which can span several inches. Their bodies are typically small to medium-sized, with lengths ranging from 2 to 10 millimeters. Anatomy of Cellar SpidersĬellar spiders exhibit unique physical characteristics that set them apart from other spiders. Even though a spider bite can be painful or uncomfortable, the venom is the dangerous part, not the bite itself. 98% of spiders are harmless and don’t pose any threat to people. In reality, most spiders don’t bite humans unless they feel threatened to do so. However, there’s no research out there to prove this to be true. There’s a myth floating around out there that cellar spiders have the most poisonous venom out of all spiders and that only their short fangs keep them from being a threat to humans. Its venom is also weak, so the cellar spider has to depend on its silk web to immobilize any prey that comes near its web. Even though it has fangs and venom glands, its fangs are quite short. While many spiders bite their prey to inject it with venom, the cellar spider doesn’t. That doesn’t necessarily make them dangerous, though. Are cellar spiders harmful?Īre cellar spiders dangerous? Cellars are harmless spiders that appear on every continent except for Antarctica and are commonly mistaken for daddy longlegs because of their leg length.Īlmost all spiders that are native to North America are venomous. This article delves into the intriguing world of cellar spiders, their characteristics, habitat, diet, and their harmless relationship with humans. They are often associated with deadly venoms due to urban myths, despite no scientific evidence supporting this. These creatures are a prime example of the gap between public perception and scientific understanding. Cellar spiders, scientifically identified as Pholcidae, are commonly misidentified as “daddy long-legs” due to their thin, elongated legs.
