What do harvestman spiders eat?
Harvestmen are omnivores, eating a variety of organic material, or scavengers, feeding on feces or carrion, but some are predatory on aphids and other small insects.

Why do harvestmen clump together?
Let's begin with #1- Harvestmen clump together for multiple reasons. First off, a clump of harvestmen looks a lot larger and scarier than a single harvestmen, so can help to cause predators to think twice about wanting to have them as a meal.

Do harvestmen have venom?
Instead of feeding, like a spider does – when a spider feeds they inject venom into their prey and that helps to break it down. But with harvestmen, since they don’t have venom, they essentially will grab their prey while it’s alive, or they’ll scavenge something that’s dead, and they will just kind of masticate it with their fangs and eat it that way.
What are the four legs of an arachnid?
The term "arachnid" refers to a group of animals that possess four pairs of legs, chelicerae (fang-like mouthparts) and appendages near the mouth called "pedipalps." The term "arachnophobia" refers to a fear of such animals. Usually, the fear is most focused on one group of arachnids known as spiders, but the other members (scorpions, mites, ticks and harvestmen) are seldom viewed favorably by humans.#N#Many people see the similarity of form and think that the harvestman, perhaps better known as the granddaddy longlegs, is a kind of spider. Spiders have two body segments (see image above). The cephalothorax is the fused head and thorax regions, which is distinct from the abdomen. Harvestmen essentially have an oval body without the separation. They also do not produce silk or a web. They are not true spiders. Venom produced by spiders helps them in their role as predators, but harvestmen do not need venom because they are scavengers. They feed by searching over the ground or over plants for small insects, eggs, or dead material (either plant or animal). For protection, harvestmen can produce defensive chemicals that taste and smell bad.#N#Small red mites often are found hanging onto the legs or bodies of harvestmen. It is not known what those mites are doing. If they feed on the harvestman, they would be considered parasites, but they would be "phoretic" mites if they merely hang on to be transported to locations that might provide a good source of food. The long legs of harvestmen are easily detached and will twitch for some time after removal. "Pacemakers" located in the first segment of the legs (called the femur) send signals that make the muscles in the broken leg tighten, but the leg relaxes between signals. Repetitive pulses of the signal create the twitches. The twitching probably attracts attention of possible predators and allows the harvestman to escape.#N#Harvestmen often will aggregate into groups in which the legs seem to be twined together and the bodies close to each other. When disturbed, a single harvestman typically pushes its body up and down in a slow, vibrating motion. The large groups will perform the same behavior if disturbed, so the pulsating mass of harvestmen may be an even greater deterrent to potential predators. Furthermore, the defensive chemicals produced by a mass may be collectively more effective, so grouping might promote greater security while the aggregation rests or hibernates.
