Above is the nest of a paper wasp in the Chartergus genus. The side of the nest has been cut away to show the combs. The entrance hole to the nest is indicated at the bottom of the nest. Each of the combs would have had a centrally placed hole to allow movement between combs. This wasp is found in South America.
Below is an old nest of
a Polistese sp. wasp. These wasps are known as paper wasps and usually have
fairly small nests in sheltered locations. This one was on the inside of a
window shutter, so it would have been in the dark.
Unlike the other social wasps nests Polistes sp. do not have an outer envelope covering the nest, and they have a much smaller nest with just a single tier of cells.
