Harvestmen, also known as daddy longlegs or Opiliones, are a group of arachnids belonging to the order Opiliones. They are characterized by their long, slender legs, cylindrical bodies, and typically non-venomous nature. While commonly referred to as spiders or insects, harvestmen are not true spiders, but rather a distinct arachnid group with over 6,500 known species.
These arachnids can be found worldwide, inhabiting various environments such as forests, fields, caves, and even human dwellings. They are most commonly observed during the autumn season, hence the name "harvestmen," as they are often found in high numbers during harvest time. Harvestmen primarily feed on small invertebrates like insects, mites, and small spiders through predation, as well as scavenging on decaying organic matter.
Harvestmen possess an elongated body comprising two main regions, the cephalothorax (fused head and thorax) and abdomen. Unlike spiders, these arachnids lack venom glands and do not produce silk to spin webs or capture prey. Despite their somewhat eerie appearance, harvestmen are harmless to humans and are valuable contributors to ecosystems. They play a crucial role in controlling populations of insects and other invertebrates, aiding in nutrient cycling by contributing to decomposition processes.
In summary, harvestmen are arachnids resembling spiders, commonly known for their long legs. They are not true spiders but belong to the order Opiliones. Found worldwide and active during harvest time, they feed on small invertebrates and organic matter. Harmless to humans, they are beneficial contributors to ecosystems.
