The European paper wasp (Polistes dominula) is an invasive species, often identified by its slender, black-and-yellow appearance (resembling yellowjackets) and trailing legs during flight. Unlike native species, they build small, open-comb nests in sheltered, dark, and often artificial areas like pipes, eaves, and electrical boxes.
Key Facts about the European Paper Wasp:
Appearance and Identification:
Coloration: Primarily black with bright yellow markings, often mistaken for yellowjackets.Body Shape: Slender with a narrow "waist".Flight: Long hind legs dangle below them while flying.Size: Similar to other paper wasps, but generally more slender.
Behavior and Ecology:Nesting: They build small, open-comb, papery nests made of chewed, saliva-mixed wood fibers.
Habitat: They prefer urban environments, nesting in hidden, dark, or enclosed spaces such as eaves, bird boxes, and utility pipes.Diet: They are predatory, preying on insects, particularly caterpillars, to feed their larvae, and also feed on nectar and fruit.Temperament: They are generally less aggressive than yellowjackets and tend to sting only when their nest is disturbed.
