How does a typical Paper Wasp nest differ structurally from an Enclosed Paper nest found in attics?

Paper wasps build an open, umbrella-shaped comb attached to a single anchor point, whereas enclosed nests are large and fully sealed

The difference between these two common paper nest types lies primarily in their exposure and overall enclosure, which relates to their specific location. Paper wasps tend to build exposed nests, often dangling from a single anchor point under an overhang; these nests are recognizable as an open, umbrella-shaped comb structure, meaning the cells face downward but are not fully surrounded by outer material. Conversely, nests found in sheltered voids like attics or wall cavities often belong to species like the European hornet. These grow into large, fully enclosed, opaque structures where the paper material wraps entirely around the internal comb structure for maximum insulation and protection.
