Did You Know?
The paper wasp nest under the eave generates anxiety out of proportion to the actual risk it poses. A nest in a location where people regularly pass close to it warrants management. A nest in a location where people do not regularly pass close to it warrants nothing except periodic observation
If This Animal Could Talk...
"Watch closely, respect my space, and let my habitat explain the rest of the story."
Polistes carolina is one of four Polistes paper wasp species in North Louisiana's 26 parishes, and the easiest to identify. That warm reddish-brown body sets it apart from the other three before you examine anything else.
Paper wasps as a group rank among the most studied colonial insects in North America, partly because their open-comb architecture makes behavioral observation easier than in enclosed-nest species, and partly because the genus Polistes generated decades of research on why some wasps live in colonies rather than nesting alone.
A Few More Facts
How they hunt and forage: Workers hunt caterpillars from plant surfaces in the foraging range around the nest, chew them to protein paste, and feed the paste to larvae in the open cells. Adult workers feed on nectar and honeydew. The protein-to-carbohydrate balance of worker foraging shifts across the season, but caterpillar hunting is the primary colony protein source throughout. The caterpillar species taken by Polistes carolina workers reflect the caterpillar community available in open and edge habitats throughout the 26 parishes. Workers hunt opportunistically within their prey size range, taking whatever caterpillar species are available on foliage within flight range. The same colony may provision cells with tobacco hornworm larvae from the garden and geometrid larvae from adjacent woodland on the same day.
Live birth or eggs? no
When young are born: Queens emerge in late February or March, worker population peaks in August, and the colony ends with the first sustained cold, typically November in North Louisiana.The Red Paper Wasp in Agricultural North LouisianaThe red paper wasp's association with open and edge habitats in North Louisiana puts it in direct contact with agricultural settings throughout the 26 parishes.

Red paper wasp colonies produce the characteristic Polistes two-register sound: a faint papery rustling at the open comb audible from a few feet in still conditions, and a sharper defensive buzz when workers are disturbed. At agricultural fence posts and field-edge structures where this species nests most consistently, both sounds carry in open air without needing to approach close enough for visual contact with the nest.
Open agricultural margins and field-edge structures throughout North Louisiana put red paper wasp nests in standing-height observation range from road shoulders and field paths throughout the 26 parishes.

Frequently Asked Questions
Does Red Paper Wasp live in North Louisiana?
Yes. Polistes carolina is one of four Polistes paper wasp species in North Louisiana's 26 parishes, and the easiest to identify. The nest on the structure near you right now, if you are in the right habitat in North Louisiana, may be Polistes carolina. The red paper wasp is the most distinctively colored of North Louisiana's four Polistes species, and the one most likely to produce a confident field identification without a photograph.
How do you identify Red Paper Wasp?
The red paper wasp is the most distinctively colored of North Louisiana's four Polistes species, and the one most likely to produce a confident field identification without a photograph. The body is uniformly reddish-brown to orange-red with limited yellow markings, lacking the strong black component that characterizes the other three North Louisiana Polistes species. The abdomen, thorax, and head are all in the same reddish-brown tone, giving the red paper wasp a monochromatic warmth that distinguishes it at a glance. That legs show yellow on the tibiae and tarsi. The wings are orange-tinted. The abdomen carries faint darker rings at segment margins but nothing that would be described as bold banding. At distance, in full sun, the red paper wasp glows in a way that the other paper wasps do not, the warm reddish tone catches light differently than black and yellow.
What does Red Paper Wasp eat?
Workers hunt caterpillars from plant surfaces in the foraging range around the nest, chew them to protein paste, and feed the paste to larvae in the open cells. Adult workers feed on nectar and honeydew. The protein-to-carbohydrate balance of worker foraging shifts across the season, but caterpillar hunting is the primary colony protein source throughout
Is Red Paper Wasp dangerous to people?
The Sting
All female Red Paper Wasp workers sting. The sting occurs in defense of the nest when the nest is disturbed, or in defense of the individual when the individual is grabbed, trapped, or struck. The colony defense response at the nest involves wing buzzing and raised-abdomen posture before stinging; workers at the nest do not typically sting without this warning display. Workers away from the nest on foraging trips are much less likely to sting than workers at the nest.
The sting of Polistes species is comparable in pain to a honeybee sting in most assessments, moderate, immediately painful, fading over fifteen to thirty minutes in most individuals without systemic reaction. Allergic reactions to Polistes venom do occur and require medical management.
That red paper wasp's reddish-brown coloration distinguishes it from every other paper wasp in North Louisiana. The fine-backed paper wasp, metric paper wasp, and ringed paper wasp are all darker, with more prominent black components. The red paper wasp stands apart visually in any direct comparison.
That only confusion species in North Louisiana is the metric paper wasp in its reddish color forms, but the metric paper wasp shows more black on the abdomen and thorax than the red paper wasp's warm monochromatic pattern. A paper wasp that reads as uniformly warm-toned rather than black-and-yellow is almost certainly Polistes carolina.
