sheepsheepDescripción
I collected some well-expired lupine seed pod stalks from Federal Way and a few days later had spiders all over the house. So far found 1 cross orb weaver, 2 zebra jumpers, 10 oak jumpers, 2 common crabs, 2 running crabs, a false black widow, a dark cobweb weaver, a tiny Phidippus, and a bunch of tiny probable cobweb weavers. INat should categorize this as an invasive species =/

White fork in the brown median stripe on carapace does not extend the full length of carapace, eliminating Pisaurina dubia.
Only two Tibellus have 4 spines on tibia I, T. duttoni and T. Chamberlini.
T. chamberlini has multiple pair of black spots on the abdomen. Eliminating T. chamberlini.
T duttoni has 1 or 2 pairs of black spots on the posterior 1/3 of the abdomen.
Also stipes on either side of median stripe appear to end near the back edge of the carapace.
