Found this colony in a rotted out 2"x8"x8' section of wood. Only used last 3 inches so I cut it off and brought it home. Have all the brood, workers and seen the queen. Have them seperated from the wood and moving into a test tube. They are about 4mm long and the queen only appears to be 1 or 2 mm longer in length. And escavator was due to demo the area they lived in so my little rescue colony.
