What are Daddy Long Legs?

Before diving into their diet, let's clarify what "daddy long legs" refers to. The term is often used ambiguously, confusing two distinct creatures: harvestmen (order Opiliones) and cellar spiders (family Pholcidae). This article focuses on harvestmen, the arachnids most people picture when they hear "daddy long legs." Cellar spiders have a separate diet, which will be briefly touched upon.

Harvestmen (Opiliones)

Harvestmen, also known as harvest spiders, are arachnids, but they are not spiders. They lack venom glands and silk-producing spinnerets, key features of true spiders. Their appearance, with long, thin legs, often leads to confusion.

What Do Harvestmen Eat?

Harvestmen are primarily scavengers. Their diet consists mainly of:

Dead insects: This includes flies, beetles, and other small invertebrates. They are opportunistic feeders, readily consuming anything decaying.
Plant matter: They supplement their diet with decaying plant material, fungi, and occasionally, nectar.
Feces: Harvestmen are not picky eaters and consume animal droppings.
Soft-bodied insects: Occasionally, they may prey upon very small, soft-bodied insects. Their feeding strategy revolves around finding readily available food sources.

How Do Harvestmen Hunt?

Harvestmen are not active hunters. They lack the specialized hunting tools of spiders. Instead, they rely on their sense of smell and touch to locate decaying organic matter. Their chelicerae (mouthparts) are used to grasp and manipulate food, tearing it into small pieces for consumption.

What Do Cellar Spiders Eat?

While not the focus of this article, cellar spiders, also called daddy long legs, are true spiders. They primarily prey on live insects, including:

Small flying insects: Flies, mosquitoes, and other small insects.
Other small invertebrates: Like springtails or mites.

They use their webs to trap prey, and they possess venom, albeit mild, for subduing their catches.

The Role of Daddy Long Legs in the Ecosystem

Harvestmen play a vital role as decomposers in their environment. By consuming decaying matter, they contribute to nutrient cycling and maintain a healthy ecosystem. Their presence indicates a generally healthy environment. They are not harmful to humans and are beneficial scavengers.

Frequently Asked Questions (FAQs)

Do Daddy Long Legs Bite?

Harvestmen cannot bite in the conventional sense. They lack the mouthparts to pierce human skin. While they might try to grasp with their chelicerae, it won't be painful.

Are Daddy Long Legs Poisonous?

Harvestmen are not venomous and pose no threat to humans or pets. This is a common myth.

What attracts Daddy Long Legs?

Harvestmen are attracted to damp, dark places with plenty of decaying organic matter. This is why they often appear in basements, cellars, and under rocks.

Conclusion

Daddy long legs, or harvestmen, are fascinating creatures with a surprisingly simple diet. As primarily scavengers, they play a crucial role in maintaining a balanced ecosystem. Understanding their feeding habits dispels many misconceptions about these harmless arachnids. Next time you see one, remember their valuable role as a natural decomposer.
