Spider Sleuthing in The San Juans – Day 7 Debunking Spider myths

Today, I’m going to introduce you to Rod Crawford in my post. Rod is the curator and spider expert (GENIUS) at the Burke Museum in Seattle. He is the go-to guy for anything you would possibly want to know about spiders.

One thing I really like about Rod are his efforts to debunk some of the most common myths about spiders. For instance, putting that spider you find in your house outdoors is good for the spider and where it belongs. Nope. Nope. Nope,….and one more big ole’ NOPE! Take a look here to read what Rod says about where some spiders live (including indoors), and why tossing them outdoors is not a good idea.

Not a Spider!

Harvestman probably Phalangium opilio

I found this the other morning (Sept. 8, 2018) when my husband had to drive over to unlock the gates at Mount Grant, San Juan Island Land Bank Preserve.

While I was waiting for him at the top, I had a chance to photograph this really interesting spider (or so I thought). It had 8 legs and looked like a spider to me, but not one I’d seen before on San Juan Island. I spent that evening going through my spider ID book without any luck.

So I sent off an email to Rod Crawford, curator of the arachnid collection at the Burke Museum in Seattle and all around “spider man” genius. Here was his response.

“Dear Cyndi,
The reason you could not find the top specimen in the Adams spider book, is that it isn’t a spider. It’s a harvestman (member of a separate order of arachnids). Even a scorpion is more closely related to a spider, than a harvestman is. Harvestmen have segmented bodies that are all in one piece (not 2 separate pieces), 2 eyes close together on a little bump, totally different mouthparts, respiratory system and reproductive system, no venom and no silk. Yours is probably the common European import Phalangium opilio.”

So, I learned something new today. I hope this will inspire you to read up on Harvestmen or Opiliones. I know that’s what I’ll be doing this evening for my light reading!
