Do not attack humans
- Daddy long legs do not attack humans. Some of their actions might be misinterpreted as attacks, however. Often when a large group of them is startled, they scatter. Their eyesight is poor, so they sometimes run directly at a person, and may even begin climbing up their legs. This is not an attack, and there’s no danger.

Daddy longlegs have simple eyes mounted on eye turrets attached to their bodies. These eyes act as light sensors and do not appear to provide more than blurry images.

The Opiliones first appeared a long time ago and have barely changed at all over millions of years. Fossils dating back 400 million years, before dinosaurs roamed the earth, look very similar to today's daddy longlegs. Because of their extensive history, researchers use daddy longlegs fossils for evolutionary and biogeographic studies. Scientists e...
Another myth is that their legs grow back. During the average lifetime, daddy longlegs have a 60 percent chanceof losing one or more legs. This can happen when a predator pulls them off or when the harvestman chooses to detach the appendage. Their gait then permanently changes. Typically, they use the two longest legs as feelers, then alternate the...
Detaching their legs isn't the only or even primary way they escape predators. Daddy longlegs prefer to blend in with their surroundings and play dead. Warning predators away with a foul-smelling liquid from their exocrine glands is another defense. The glands are unique to these arachnids and are also used to communicate with other harvestmen. Som...
Daddy longlegs have small, hairy appendages near their mouth used as sensory organs called pedipalps. Using high-speed cameras, researchers discovered the hairs on the pedipalps secrete a glue-like substance to capture prey.They embrace their mark with their pedipalps and apply the secretion in milliseconds. With only a few microscopic drops, the g...
Groups of daddy longlegs sometimes form thick clusters called aggregations. Aggregations contain three or more huntsmen, with one enormous assemblage containing 300,000 individuals. Once created, the mass can stay in place for months, particularly during winter. Researchers speculate that aggregations form for mating, temperature control, humidity ...
