I found three of these tiny underbark Laemophloeids clustered beneath the bark of a small deciduous log or large branch. I recognized them as a species I had photographed previously due to their very reflective elytral facets. (These glint brightly in the sunlight as the beetle runs for shelter.) These guys were very slow-moving due to the cold. Back at home in my warm light arena, they were active enough to fly. Those pix will be along later.
