This weekend we took a trip with some entomology students to the Vermillion River Observatory. The astronomical function of the observatory has long been abandoned, but the site remains as a lovely nature reserve and one of the closest patches of decent forest habitat to where we live in Champaign-Urbana.
The acrobat ant Crematogaster lineolata was one of many ants we encountered, and in this nest the queen was right up near the surface. She lingered long enough for me to get a few shots before she disappeared into the labyrinth of tunnels.
