Hunter's Little Paper Wasp

Fascinating facts about the Hunter's Little Paper Wasp

• A Polistes dorsalis wasp can fit on the tip of your finger, its fore wings measuring just 11-17 mm long, about the width of a fingernail. This tiny size makes it one of the smaller Polistes species, letting it slip into narrow crevices and hidden shelters that larger wasps cannot reach. Its shield-shaped exoskeletal plate is dark with a bright yellow band, and the antennae's flagellomeres are dull orange rather than sharply tapered. These subtle color cues let naturalists tell it apart from close relatives like P. fuscatus. Such compact design lets the wasp build discreet, low-ground nests that stay out of sight from predators and humans alike.
• A single Polistes dorsalis nest can house up to 75 adult wasps, yet the whole colony fits on a single open-faced paper comb that hangs from a sheltered spot like a rock pile or hollow log. Because the nest lacks an outer envelope, it stays lightweight and can be tucked under shrubbery or the lower edge of a roof in urban gardens. The modest size means the colony can be established close to the ground, reducing exposure to wind and aerial predators. This hidden, low-profile architecture helps the wasp thrive in both wild fields and city backyards, making it a common yet often unnoticed neighbor.
• Polistes dorsalis faces a hidden threat from the ectoparasite Elasmus polistis, which lays its eggs on early-stage pupae inside the wasp's sealed cells. In one recorded nest, researchers found as many as 103 parasitic pupae crowded onto a single Polistes host, each larva devouring the wasp pupa until only indigestible material remains. The parasite then builds a protective wall of its own feces inside the cell, shielding itself from the wasp workers that might otherwise destroy it.
• Polistes dorsalis was first described by Fabricius in 1775, and since then five subspecies have been described, two of them in 1949 (P. dorsalis californicus and P. dorsalis clarionensis) and two in 1940 (P. dorsalis maritimus and P. dorsalis neotropicus).
• When disturbed, Polistes dorsalis delivers a sting that scores a 2 on Christopher K. Starr's 5-point pain scale. The sting's impact depends on colony size; larger groups are more likely to attack with less provocation.
