Wolf spiders prey upon many insects such as crickets and ants and have been seen catching other spiders as well. They are even known to stalk and catch small lizards, frogs, mice and tiny birds.
Wolf spiders stalk their prey much like wolves do in the wild, which is how they got their name. They don't weave webs like other spiders, but locate potential prey with their keen eyesight. They then attack and overpower their prey with superior strength and speed. However, the wolf spider can't actually eat meat if it happens to catch a small mouse. Rather, it drinks the liquid out of its prey with a sucking motion that resembles using a straw.
