As dusk loomed, I searched webs on a boulder while Rod finished sifting moss. A couple hiking past asked if I was collecting moths, and was I a biologist. They were interested to learn that I was looking for spiders, asked to see some, and said they were excited to get back to camp and tell their kids that they'd met a real biologist on the trail. Now that made my day!

|Known distribution of Ozyptila praticola |
in Washington (so far)
I returned to my previous sampling location in Issaquah, knowing that there were some untapped cones there dropped by "weeping" white pines (probably Pinus monticola 'Pendula'). This being late autumn, and judging from my recent experiences, I knew the likelihood of finding an adult Ozyptila praticola in any particular cone was not high. But I also knew that the likelihood would increase with each cone I tapped.

Weather may force me to suspend further eastward sampling until spring. Until then, I will probably refocus my search southward, towards Tacoma.

Black pine (P. nigra) trees planted in front of a local business provided me with 45 tappable cones and 14 spiders. Half of them were Ozyptila, but they were all juveniles, and all praticola in appearance. The day before, I had thought that there was nothing more annoying than finding one juvenile Ozyptila probably-praticola, but I was wrong. It was much more annoying to find seven of them!
