Myth bashing: Are daddy longlegs spiders?

The answer is yes and no. It turns out that someone wasn’t very creative when naming little critters with long legs, and it can lead to a lot of confusion!

The critters most commonly referred to as daddy longlegs are not spiders. They are Opiliones and also known as harvestmen. They are also arachnids, but are more closely related to scorpions than to spiders. A few characteristics differentiate Opiliones from spiders. For starters, Opiliones just have two eyes. They cannot produce silk and therefore cannot make webs. They also lack venom glands. Spiders usually have two distinct body segments, but Opiliones have a compact oval-shaped body. It looks like one segment but the cephalothorax and abdomen are fused together so that the joint … Continue Reading (2 minute read)

    They’re not *completely* harmless. One time I went camping with my family and my brother woke up because one crawled on his face. He was covered in them. We don’t know why they chose his tent to spend the night in, but there they were, hundreds of them. He screamed and tried to get out of the tent, but it was one of those 2-layer zip doors and he only got the first one unzipped, so he got stuck in between the tent layers and rolled the tent over on top of himself, which presumably freaked the spiders out, so they were scurrying every which way. Anyway, the spiders themselves didn’t do anything, but my brother had nightmares for years, and has a severe phobia of spiders now into his late 30s. Just wanted to share this story about my brother.

    Too many people believe these little dudes are “the most venomous spiders alive” but that their mouths are too small to bite people. Who knows where it started but goddam that myth has spread.

    Seems like a lot of bugs have this moniker. There was another kind of bug peopple called ‘daddy long legs’ when I lived in England that iirc was something different again.

    Also, fun fact: Their name comes from the fact that they have a symbiotic relationship with bees, who bring their dead just outside the hive. Then the Harvestmen come to reap the dead.
