Each fall, large numbers of tarantulas skitter across the landscape in La Junta and southeast Colorado.

While this phenomenon has traditionally been called a migration, it is actually an annual mating ritual performed by male tarantulas who roam across the 443,000-plus acres on the Comanche National Grassland looking to mate.
