Arachnids consist mostly of spiders, mites, scorpions, ticks, and harvestmen. Commonly mistaken for insects, arachnids have many differences which separate them evolutionarily. The easiest and main difference is all arachnids have 4 pairs of legs, compared to insects which only have 3 pairs of legs. Some arachnids front pair of legs have been modified into sensory structures. Spiders especially help control insect populations, and in China and Israel, have been used as pest control in apple orchards and rice fields.
