The term daddy long legs can actually refer to any of three distantly related groups of arthropods.
1 various members of the family Pholcidae, also known as cellar spiders, particularly the species Pholcus phalangioides also known as the Skull Spider
2 various members of the family Tipulidae, commonly called crane flies. These winged insects bear no resemblance to spiders
3 various members of the order Opiliones, also known as Harvestmen. These are arachnids and are commonly mistaken for spiders, but they are not closely related to true spiders. They are probably closer to mites or scorpions. Unlike spiders, they do not possess ether silk or venom glands, and their two main body segments are joined together so that they appear as one oval structure. More than 6,500 species of harvestmen have been identified, and more than 10,000 are estimated to exist. Although some exotic shorter legged species look more like beetles or crabs, most are known for their very long thin legs.
What you recall seeing were probably a variety of harvestmen.
