Polistes major or Polistes carnifex
The large wasps of about 4 cm were bright yellow with brown bands. They were drinking water in a splash zone next to the river. The distributions of both these very similar wasps includes Chiapas, Mexico.
Tropical Forest, dry season, Chorreadero Park, 10 km above Chiapa de Corzo, Chiapas, Mexico.
