Two castes of paper wasps are genetically identical. Larvae turn into either workers or potential queens, depending on the behavior of adults, say University of Wisconsin scientists. If adults drum on nest walls with their antennae, the vibrations inhibit fat storage and produce workers.
Learn more about paper wasps at the Encyclopedia of Life.

Is it possible to retrieve a video advertised in a November 2006 issue of Smithsonian Magazine? "The trap-jaw ant in action" How does this compare with the Sea creature in the April 2011 issue of Smithsonian Magazine? (Sorry, someone in the family has moved our copy for the moment.)
