ponderosa pines near Bear Creek
Alas, despite slogging though wet grass and hopping rose-guarded creeks, I only found 26 cones to tap. The result was only two juvenile spiders, although one was an Ebo sp. (Thomisidae). Only a handful of adult Ebo have been collected from any microhabitat in Washington. As for the litter, which was bone dry despite the general dewiness of the area, I got skunked (see Def. 5)!
Our collecting area was about 2.5 miles up the canyon from its mouth on the Columbia River. Here the flat, grass-covered canyon bottom gave way to a pocket of wetlands. To my delight, ponderosa pine groves were growing on both the canyon bottom and the canyon's south-facing slope, with a few lone trees at the foot of the north-facing slope. Lots of possibilities!

In any case, these cones had spiders! From 150 cones total I collected 8 species and 67 individuals including 34 juvenile Steatoda sp. (Theridiidae), three Euryopis formosa and a female of the infrequently found crab spider Xysticus gulosus (Thomisidae). Even that threadbare needle litter produced two juvenile spiders.

Next stop, Spokane County!
