Common Spiders of Portland, Oregon
|
||||||||||
| The purpose of this website is to help people identify some of the most common spiders found in homes, yards, and natural areas in and around Portland, Oregon, and Vancouver, Washington. The site also includes information on the behavior of spiders, and on where and when one is most likely to find them. Links to websites with additional information on spiders, as well as organizations dedicated to spiders, are included at the bottom of this page.
A spider’s diet consists primarily of living insects, or sometimes, other spiders. One way to categorize spiders is by how they hunt their prey. We can divide spiders by their hunting techniques into those that build webs ("web-building" spiders) and those that rely on active hunting ("wandering" spiders). These two categories can be further divided, either by the type of web a spider builds (for example, orb-web versus cobweb), or by the strategy it employs when actively hunting (for example, ambushing versus stalking). This website groups spiders first by where one might find them, and then by their hunting technique. Common Spiders of the Yard & Garden (This link is under construction)
