|Ponderosa cone site in Everson|
The tapped cones yielded 11 spiders and 4 species, plus 7 adult harvestmen. As I've found in other cone samples in western Washington, many of the spiders present and all of the harvestmen were introduced species. However, Ozyptila praticola (Thomisidae), which we have found in great abundance in the Seattle area, was not among them. Further, we didn't find it in any of the other microhabitats we sampled in the area, and Rod hasn't collected any from other sites he's sampled in Whatcom County. If the species has spread south from the Vancouver area, its presumed point of introduction in British Columbia, we have yet to detect it in northern Washington state.
