Big Pacific NW Centipede

Big Pacific NW Centipede
Seattle, King County, Washington, USA
September 23, 2006
Size: approx 27mm
This is the first photo I took after my brother was kind enough to lift a large container on our patio. It shows 2 centipedes with some sowbugs for scale (I made my measurements based on the sowbugs, so it is only an approximation). I'm showing both in this submission because they were found at the same time, and are the same species. (I will add what I think the species is, when I can find my darn book--Plants and Animals of the Pacific Northwest) (1). It has a good section on some of the non-insect invertebrates in this area.

I was wrong, again...
Well, I found my book (Plants & Animals of the Pacific Northwest)(1). It is (I am sure!), a type of European Centipede, Lithobius forficatus. It reaches a length of 3cm. "It hides under boards, bricks, flowerpots, and the like."

Which measurement is correct?
If the European centipede only reaches 3 cm (30 mm) then either 55 mm is incorrect, or European Centipede is not the correct ID.

I'm sorry, I meant to correct
These specimens were 27 or 28mm in actuality.
The large native centipedes in my area are differently colored and found in forest settings, from what I've read.

Wrong size noted
I "upped the measurement" because on actually looking at a metric ruler, I realized that I was way off. I truly believe that this is an average size for these guys.

They are really fast, too!
