Another sampling event in the
catch-as-catch-can category, this time in the Highlands area of Bellevue. Although I usually keep my nose to the grindstone on spider collecting ventures, especially short ones like this (I had only 2 hours, less if it started raining), I couldn't resist taking the time to stop at one of the area's numerous Indian grocery stores first to stock up on snacks. What a treat!

Cone source: Pinus nigra trees |
|
Cone microhabitat, scales hardly open |
Not far from the grocery I found my cone source: eight black pines (
Pinus nigra) planted along 140th Ave NE. These trees had been heavy cone producers, but few of the cones had more than a few scales even partially open. I see this repeatedly in
P. nigra in western Washington, where this exotic tree species is widely planted.

Tenuiphantes tenuis in my net |
|
Preserved Erigone male |
With some diligent searching, however, I managed to scrounge up 50 of these barely-opened cones, and tapped 9 spiders from them. Immediately identifiable were female
Tenuiphantes tenuis and
Tachygyna vancouverana, both from the family Linyphiidae and both species I tap frequently from cones in the greater Seattle area. The other identifiable species was another linyphiid, an
Erigone male. I'll have to wait for the specimen to cure before I can identify it to species. I've tapped an
Erigone from cones only once before: a male
E. aletris last October in
Lynnwood.
