Ropalidia Paper Wasps are very small; they occur in Southeast Asia, India, Australia, Africa and Madagascar.
These wasps are narrow waisted brown wasps with black, yellow, grey or white markings on the body.
All species build communal papery multi-celled nests of wood pulp and saliva, attached by stalk to plants, rocks or buildings. Very social and defend their nests aggresively. Larvae are fed on chewed-up, soft-bodied insects such as caterpillars. Nests are abanoned at the end of the season.
