Nice turret spider hole.

Finally managed to spot some of these spiders in their turrets, and I even managed to coax a few further up by flicking a twig around the entrance. Sadly, none of the did more than inch forward to investigate.

Most of my attempts to illicit strike responses from turret spiders end in failure, but for whatever reason Trent was able to get this one to cooperate. I tried to reciprocate but again without luck. Trent was gently stroking the edge of the turret with a twig, whereas I was poking it, so maybe the key is to immitate a smaller insect. There's anecdotal evidence to suggest that they eat ants, so maybe think ant-sized movements. Also, you need to do it under cover of full darkness for them to be staged near the burrow entrance (though they seemed willing to strike under flashlight illumination). Note the deep, transverse foveal groove and the sclerite on the abdomen, both indicative of the former genus Atypoides (Adams 2014).

California Turret Spider Burrow

Richard showed us a whole bunch of these structures.

I guess this is a spider burrow: a conical silk-lined structure incorporating forest debris. Seen in a forest of Douglas Fir and Coast Redwood. Several others were nearby with smaller apertures; the fourth photo is one of these. Similar structures with the Foldingdoor Spider Anthrodiaetus riversi have been posted from Pepperwood.
