Note:  This is not a scientific site but merely a photographic journal.  I know nothing about spiders except what I learn through asking experts or
from mere observation so my guess at identification of spider species may be right or wrong.  Contact experts at your extension service for precise
 identification.  These photos are for your enjoyment or to give you a general idea of what spider you may be seeing around the house or cabin.  The
more you learn about nature, the less you have to be afraid of everything that scurries your way.  Copyright information is at the bottom of the page.

I love this quote by Rod Crawford from the Burke Museum "...house spiders are mostly harmless and beneficial. Human property rights
mean nothing to other species. There was spider habitat for millions of years where your home is now. My advice is, 'just wave as they go by.'"

  Note: All spider identifications are merely a guess by a spider admirer. Input from experts would be
greatly appreciated! (birdbrain@amazingnature.us) Thanks to Bugguide.net for helping to identify the arachnids on this site. If you
want to see detailed information on the parts of a spider, I found a Belgian website, presented by
Gie Wyckmans, that is very detailed.
