Koch's wolf spider is a brown and grey hunter that runs fast over the ground. It does not build a web to catch food. Instead it chases insects, like a little wolf. The mother carries her babies around on her back.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
