Daddy Long legs, or harvestmen, are not actually spiders. Daddy long legs are not poisonous, have long legs and a large bulbous-looking body. They feed on insects, which makes them helpful around the garden. They are especially active at the time of harvest, toward the end of summer and beginning of fall. They are visible during this season because it's generally the time when they mate.
