While I photographed it, this individual seemed very interested in shadowy hiding-places; it escaped me several times and each time had a knack for quickly finding very narrow crevices in which to hide. The last time it found a crevice (a seam of caulk separating from a window frame), it ran along the wall up to the crevice and then backed into it, which I thought was interesting.
