How Common Are Paper Wasps?
WouterSeveral species of paper wasps are found in North America and around the world. They are members of the vespid subfamily of the insect family Polistinae. The family contains more than 300 species. They live in woods and forests, but can also be found in urban areas. They feed on flies and other insects, and build paper-like nests.
Paper wasps are generally black or brown, and have long legs. Their wings are folded lengthwise. They have a narrow petiole between the thorax and abdomen.
They are also referred to as cuckoo paper wasps because they use their nests as a means of raising brood. They are obligate social parasites. They live on their hosts’ nests and use the pheromones of the host to communicate with each other. They also use the host’s food to feed the larvae.
A paper wasp colony typically consists of less than 100 adult wasps. The queen is the key to the future of the colony. She defends the nest and actively seeks food and other nesting materials. Other females may help with the nest and care for the larvae. In addition, paper wasps may swarm in large numbers.
Paper wasp nests are constructed of a mixture of wood fiber and saliva. They are made in protected locations such as porch ceilings and roof overhangs. They are also often seen hanging from tree branches or twigs.
When a paper wasp nest is disturbed, it is likely to sting. They will sting to defend their nests and to protect their queen. They may also sting if they are pressed against skin.
