Brandão and Vinson outside Valhalla (IMAGE) Rice University Caption Pedro Brandão-Dias (left) and Camila Vinson outside the door to Valhalla with a photo of the nonstinging wasp species they discovered nearby. Neuroterus valhalla, which is just 1 millimeter long, was named for the Rice graduate student pub because it was discovered in a tree just outside.
