Common Spiders in Seattle: A Guide to Local Arachnids
Seattle, with its damp climate and lush greenery, provides a suitable habitat for a variety of spiders. From harmless house spiders to more noticeable orb-weavers, understanding the common spiders in the area can help you identify and coexist peacefully with these creatures. This guide explores some of the most frequently encountered spiders in Seattle and provides information about their characteristics and habits.
Common Seattle Spiders
House Spiders
Several species of house spiders thrive in Seattle homes. These spiders are generally small to medium in size and often build webs in corners, ceilings, and other undisturbed areas. Common examples include the American house spider (Parasteatoda tepidariorum) and cellar spiders (family Pholcidae), also known as daddy long-legs. These spiders are beneficial as they prey on other insects.
Orb-Weaver Spiders
Orb-weavers are known for their intricate, circular webs that they construct to trap prey. Various species of orb-weavers are common in Seattle gardens and parks, especially during the late summer and fall. These spiders are generally harmless to humans and play a role in controlling insect populations. You can learn more about Orb-weaver spiders on Wikipedia.
Hobo Spiders
The Hobo spider (Eratigena agrestis) has a reputation that often precedes it. Native to Europe, these spiders have become established in the Pacific Northwest, including Seattle. They are funnel-web spiders, meaning they build webs that lead to a retreat where they wait for prey. While their bite was once considered medically significant, current research suggests that the venom is not as potent as previously believed.
Wolf Spiders
Wolf spiders are large, hairy spiders that are known for their hunting prowess rather than building webs. They are often found in gardens and wooded areas around Seattle. Wolf spiders are active hunters and are capable of moving quickly to capture their prey. Female wolf spiders carry their egg sacs on their spinnerets and later carry their young spiderlings on their backs.
Jumping Spiders
Jumping spiders are easily recognizable by their distinctive jumping ability and their large, forward-facing eyes. They are active hunters and do not build webs to trap prey. These spiders are often brightly colored and can be found on plants, walls, and other surfaces around Seattle homes and gardens.
