|The fallen cone microhabitat|
Tapping 60 cones, I collected 48 spiders and 14 species from 7 families. Compared to my eastern Washington cone samples, where I'm lucky to collect 6 species per site, this sample was exceedingly rich. Being in Puget Sound, I suppose it wasn't too surprising that 3 of the species were introduced.
Interestingly, the most numerous species in my cone sample was Neriene litigiosa (Linyphiidae). Commonly called the Sierra dome weaver, this species is most often collected from vegetation or aerial webs, but also pitfall traps. So far, this site remains the only place I've collected it from cones.
