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. The study is published in Behavioral Ecology and Sociobiology. A stained cross-section of a Leipolmeles wasp shows different brain regions. O’Donnell’s study showed that paperwasps in different castes had different-sized sensory brain regions. “The wasps in different castes within a colony don’t differ much genetically. The differences we see show the signature of the environment on brain development,” said Sean O’Donnell, PhD, a professor in Drexel University’s College of Arts and Sciences who led the study. O’Donnell’s team found that the queen wasps had smaller brain regions for processing visual information than the workers in their own col
