Wolf Spiders (Family Lycosidae)

Wolf Spiders are characterised by a top row of 2 medium-sized eyes, a middle row of 2 large eyes and a bottom row of 4 small eyes. They have good eyesight and sense of touch. They carry their egg sacs in a "white ball" under their abdomen and after hatching, the young ones piggyback on the parent.
