The Eternal Verities of Tarantulas


Yesterday at the grocery store in Pueblo, the conversation was about tarantulas — one of the employees explaining how he tries to usher the huge spiders out of the house before his wife sees and kills them.

It's that season:

Every year, 10,000s of male tarantulas start marching around the southern part of Colorado, typically from late August through October as summer nighttime temperatures cool.
The eternal verities: we Homo saps might all vanish, but giant hairy spiders will still march across the land.

Generally, the first tarantulas to appear will show up in southeastern Colorado around the end of August, roaming throughout the month of September. A second, southwestern wave will appear a bit later in the year, with their presence peaking in October. These fuzzy fist-sized arachnids creep around on a quest to find a mate and after mating, they'll die — typically at the hands of their mate or due to cold weather.

They really should be the mascot for Colorado State University-Pueblo, not the made up-by-a-committee "thunderwolf":

Lira is a student ambassador at CSU-Pueblo, and she often leads campus tours for prospective students and their parents. During these outings, Lira touts the tarantula as a captivating aspect of the campus that sits on a bluff above the Arkansas River several miles from downtown Pueblo. It’s not uncommon to see a tarantula skirting an open expanse as summer cedes to fall. But don’t worry, Lira assures visitors, sightings are intermittent, and the spiders are not harmful to people.

“It’s one of my engagement points when I talk to students because it’s one of the unique things they might experience here,” said Lira, a junior on a pre-veterinary track. “Not having a city impede on you allows you to see the wildlife around us, and tarantulas are part of what you might see. It’s cool being on the outside of the city because you get to experience the prairie. It’s an opportunity for discovery.”

Let the rhythms of nature sooth you.
