Wyoming is home to a diverse range of spider species. Whether you’re hiking in a national park or simply exploring your backyard, it’s likely that you’ll encounter some of these eight-legged creatures. Here are some of the common spiders found in Wyoming:

Wolf Spiders

Wolf spiders are abundant in Wyoming and can be found in various habitats. They are typically ground-dwelling creatures and do not create webs to catch prey. Instead, they actively hunt and pounce on their victims. Wolf spiders can vary in size and coloration, but they are generally brown or gray with distinct patterns on their bodies.

Cellar Spiders

Cellar spiders, also known as daddy longlegs, are commonly found in homes and buildings throughout Wyoming. They are often seen in corners or basements, where they spin irregular and messy webs. While their appearance may be off-putting to some, cellar spiders are actually beneficial as they help control the population of other insects, including venomous spiders.

Crab Spiders

Crab spiders are known for their ability to change color and blend in with their surroundings. They are often found near flowers and use their camouflage to ambush unsuspecting prey. Crab spiders do not spin webs but instead rely on their agility and stealth to catch their meals.

Daring Jumping Spiders

Daring jumping spiders are small but agile hunters. They are known for their impressive jumping ability, which they use to pounce on their prey. These spiders have excellent eyesight and can often be seen exploring their surroundings, ready to spring into action.

American Grass Spiders

American grass spiders, also known as funnel-web spiders, are commonly found in grassy areas, gardens, and fields. They create funnel-shaped webs that serve as both a shelter and a trap for their prey. American grass spiders are fast and can move quickly to capture their victims.

Notable Wyoming Spiders: Black Widows and Fishing Spiders

Wyoming is home to some notable spider species, including the venomous Black Widow. These spiders are easily identifiable by the distinctive red hourglass mark on their abdomen. While Black Widows are not aggressive towards humans, their bites can be dangerous and should be treated as a medical emergency. If bitten by a Black Widow, seek immediate medical attention.

Another fascinating spider species found in Wyoming is the Fishing Spider, also known as the Dock spider or Wharf spider. These spiders are typically large in size and are commonly found near water sources. They are known for their unique ability to run on water and catch prey, including small fish. Fishing spiders are nocturnal creatures that prefer to stay close to their aquatic habitats.

Both Black Widows and Fishing Spiders play important roles in Wyoming’s ecosystem. While Black Widows may be venomous, they help to control the population of other insects in the area. Fishing Spiders, on the other hand, contribute to the balance of aquatic ecosystems by preying on small fish and insects that live near or in the water.
