Worker wasps grow visual brains, queens stay in dark

A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new 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.
