Every year in the late summer, early fall there is a migration of 8 to 10 year old brown back Oklahoma tarantulas looking for mates. The females are hunkered down in burrows on the plains. While they can live to 20 or more years of age their mates die soon after the mating. We “patrolled” highway 109 between La Junta and Kim, Colorado for a glimpse.
