Aug. 9 (UPI) -- At dusk across highways in south-eastern Colorado, thousands of Oklahoma brown tarantulas are beginning their annual trek searching for mates. The hairy eight-legged beasts, about 3 inches long, migrate in large numbers near La Junta, Colo.
The males are about 10 years old and have only one chance to mate with females who wait in burrows in the Colorado grasslands, said Whitney Cranshaw, entomology professor at Colorado State University.
