what is the niche of the harvestmen?

Answer 1

They fill the niche of creepy organisms that people feel compelled to squish. Otherwise, they are nocturnal scavengers that prey on other invertebrates, and they also eat plants, fungus, detritus, and dead insects. . They might be considered a generalist, with respect to their feeding habits since they eat such a wide variety of foods. All they need to survive is a temperate climate, and a moist place with organic material.
