image: A femal paper wasp (Polistes metricus) on her recently founded nest, in this case constructed in the laboratory from source materials in University of Illinois school colors.

This image relates to an article that appeared in the Sept. 28, 2007, issue of the journal Science, published by AAAS. The study, by Dr. Amy L. Toth and colleagues at University of Illinois, Urbana-Champaign in Urbana, Ill., was titled: "Wasp Gene Expression Supports an Evolutionary Link Between Maternal Behavior and Eusociality." view more
