Desert Harvestmen (Order Opilones)

Harvestmen superficially resemble spiders, but they actually belong to a different order (spiders belong to the order Araneae. They are also called "daddy long-legs," but this name is also used for crane flies (Tipulidae) and cellar spiders (Pholcidae). Unlike spiders, they have no fangs and do not inject venom. In addition, their abdomen is fused to the cephalothorax. They typically have only two eyes on a single turret-like tubercle at the top of their head region. The second pair of legs are longer than the others, and are used like tactile antennae. Harvestmen are typically scavengers that feed on dead insects, spiders and pillbugs (isopods). Apparently the first species to be described were seen in the fall during harvest time.
