   Ian Cooper photographed this spider  in a hollow of a large conifer’s rough bark at dusk at Colquitz River Park.  Dr Robb Bennett comments:

If it is a “relatively” big spider  it may be a female Pimoa altioculata. If small, then it could be one of several linyphiids, e.g., a species of Bathyphantes (among whom the pimoids used to be classified).

Jeremy Tatum writes: A subsequent photograph of it next to the tip of a key shows that it was really quite a small spider, and further close-ups showed that it is Bathyphantes.

Further comments by Dr Bennett after seeing the additional photographs:  I’m pretty sure now that this spider is a female linyphiid in the genus Bathyphantes. It is quite likely Bathyphantes keeni.

   Ian also took more photographs of a harvestman, which I think is his Oligolophus tridens

   Ian also photographed the caddisfly-larva-like case of the caterpillar of a tineid moth on a treetrunk.  You can just see the head of the caterpillar poking out of the upper end of the case.
