Worker wasps grow visual brains, queens stay in the dark
January 6, 2014
A queen in a paperwasp colony largely stays in the dark, but worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new Drexel University study indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the different behavioral reliance on the senses. The study is published in Behavioral Ecology and Sociobiology.
