Tarantula Migration
Tarantulas Wandering in Southwest Colorado: A Unique Natural Phenomenon
Every fall, a fascinating event unfolds across the plains and foothills of Southwest Colorado—the annual tarantula migration. It’s a natural spectacle that draws attention not only from local residents but also from nature enthusiasts and curious onlookers from across the country. While the thought of hundreds of large, hairy spiders might send shivers down some people’s spines, the tarantula migration is actually an incredible and harmless display of nature at work.
What Is the Tarantula Migration?
The tarantula migration is not a migration in the traditional sense, where animals move long distances for survival or food. Instead, it’s a seasonal event where male tarantulas—most commonly the Aphonopelma hentzi species—emerge from their burrows in search of mates. These bachelors are driven by one purpose: finding love before the end of their short adult lives. Think of it like nature’s speed dating, but with way more legs and a lot less talking.
Starting in late August and continuing through October, the males set out at dusk, bravely trekking across fields, roads, and even hiking trails in their quest for romance. While this phenomenon occurs throughout the southwestern U.S., Southwest Colorado—particularly around La Plata and Montezuma Counties—offers a prime viewing opportunity for those wanting to witness this spidery love parade.
Why Do Tarantulas Migrate?
The male tarantulas, typically between 7 and 10 years old, have spent their lives underground, feeding and molting in their solitary burrows. But after years of being single, they’ve had enough and emerge during the fall to search for that special someone—because even spiders can’t resist the call of love. Mating is their one and only mission now, and after they find a mate, they’ve basically checked off their entire bucket list.
Females, on the other hand, are much more grounded (literally and figuratively). They prefer to hang out in their burrows, waiting for Mr. Right Now to wander by. With a lifespan of up to 20 years, they take their time, knowing the males will come knocking. Unfortunately for the guys, some of these spider dates don’t always end well—cannibalism is a real possibility. Talk about a high-stakes romance!
Where to See the Migration
In Southwest Colorado, several areas are well known for good tarantula spotting. The flat grasslands between Cortez and Durango, particularly around Highway 160, are a great place to witness the migration. It’s not uncommon to see these large, slow-moving romantics crossing roads or meandering through open spaces, likely dreaming of the perfect spider wedding.
For those who wish to experience the tarantula migration, it’s best to go out just before sunset, when the males become more active. Be sure to bring a flashlight if you plan to stay after dark, as the tarantulas tend to be most active at dusk and into the early evening hours.
Are Tarantulas Dangerous?
Despite their intimidating size and appearance, tarantulas are generally not dangerous to humans. Sure, they look like they could headline a horror movie, but they’re just hopeless romantics in search of a mate. While they can bite if threatened, their venom is mild and typically not harmful beyond a bee sting in terms of pain or reaction. They’re much more interested in finding love than engaging with humans, so if you come across one, it’s best to observe from a respectful distance and let them continue their search for spider soulmates.
Tarantulas also play an important role in the ecosystem, keeping populations of insects and small invertebrates in check. Their presence is a reminder of the often-overlooked importance of spiders in maintaining balance in nature—whether they’re swiping right on their tarantula Tinder or not.
How to Enjoy the Tarantula Migration Safely
If you plan to observe the tarantula migration, there are a few things to keep in mind to ensure both your safety and the well-being of these eight-legged Casanovas:
- Watch from a distance: Tarantulas are delicate creatures. Avoid picking them up or disturbing them on their journey for love.
- Drive carefully: If you’re on the road, be mindful that tarantulas are slow-moving, and it’s easy to accidentally run them over. Drive cautiously in known migration areas, especially during the evening.
- Respect their habitat: Stick to trails and paths, and avoid trampling through their natural habitats. Many of these areas are fragile ecosystems.

So, whether you’re a spider enthusiast or simply curious about the natural world, the tarantula migration is a spectacle worth seeing—if you’re brave enough to witness nature’s ultimate matchmaking event.
