Northern Paper Wasp

Northern Paper Wasp

Polistes fuscatus

A species of Dominula-group paper wasps, Also known as Common Paper Wasp, Hypervariable Paper Wasp

The northern Paper Wasp (Polistes fuscatus) has a complex society that is dominated by one queen. The first children that a queen gives birth to are infertile females, giving them the regular job of maintaining the nest. Much like human societies, northern Paper Wasps pamper their youth. There are no nursing homes for the elderly.

Appearance of Northern Paper Wasp
The male is identified by its darkened apical flagellomeres in addition to its darkened dorsal surface of the apical flagellomeres that is common to other species of wasps. The facial and abdominal markings of Polistes fuscatus are highly variable, including a variety of different patterns, such as small dots, long stripes, clypeus blotches, yellow abdominal dots, upper clypeus stripes, and combinations of both clypeus edge and tip colorations. Furthermore, some wasps have these facial and abdominal patterns in brown and black instead of yellow.The length of Polistes fuscatus often ranges between 1.5 cm and 2 cm. The fore wing length ranges between 1.2 cm and 1.7 cm; in general, the fore wing of males is above 1.3 cm, whereas females have a fore wing length above 1.1 cm.

How to Identify Northern Paper Wasp?

Life Cycle of Northern Paper Wasp
Egg The egg stage of northern Paper Wasp begins after a female deposits her eggs. They are often oval and small, tiny enough to be overlooked. The eggs embody potential for new individuals, but they remain static and show no visible signs of the insect within, except for size increase over time.
Larva During the larval stage, northern Paper Wasp manifests notable changes, growing considerably and shedding its skin multiple times. The larvae are typically worm-like, lacking wings and developed reproductive structures. They focus primarily on feeding to accumulate energy for subsequent transformations.
Pupal In the pupal stage, northern Paper Wasp undergoes significant transformation inside a protective casing. The size of northern Paper Wasp changes minimally, but its shape, color, and function evolve dramatically as it prepares to emerge. The pupa remains mostly immobile as its body reorganizes.
Adult Emerging from the pupa, the adult northern Paper Wasp's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction and may exhibit brighter colors or diverse markings for its final life stage.

How Can You Attract Northern Paper Wasp
Northern Paper Wasp are attracted to sugars and proteins. Sweet baits or meat can be used as traps.
Rectangle
Habitat Preferences of Northern Paper Wasp Through Different Life Stages
Northern Paper Wasp eggs are typically laid in protected environments like the inner walls of nests often attached to sheltered structures, such as eaves of buildings or dense vegetation. Larvae are found within the cells of these papery nests, where they grow and pupate. To find them, one must carefully inspect the nesting sites, usually above ground level. Mature northern Paper Wasp adults can be spotted foraging for food. They are often near flowers, flying around structures where they might build nests, or visiting various plants. Searching different plants and flowers during daytime or observing areas with potential food sources can yield sightings of adult northern Paper Wasp.
Rectangle
When is the Best Time to Observe Northern Paper Wasp
The best time to find northern Paper Wasp is usually during daylight hours when they are most active, especially in the warmer months.
Rectangle
What is the Best Weather to Observe Northern Paper Wasp
Northern Paper Wasp are most commonly found in warmer weather with low wind conditions, which are ideal for their activity and flight.
Rectangle
How and Where Can You Find Northern Paper Wasp at Different Life Stages
Larva Northern Paper Wasp larvae are typically found inside their nest, which is made of a paper-like material. To find them, look for nests attached to structures or plants, but approach with caution to avoid disturbing the nest.
Pupal During the pupal stage, northern Paper Wasp remain within their cocoon inside the nest. Finding them would involve carefully observing the inside of the nests without causing harm or disturbance.
Adult Northern Paper Wasp adults can be found outside the nest, often foraging for food. To find adults, observe flowers, fruits, and other food sources that northern Paper Wasp might be drawn to for feeding.

Are Northern Paper Wasp harmful to humans?

Northern Paper Wasp has a sting needle at the tail, which can sting people. But it is not aggressive and rarely attacks humans unless it is threatened. Even so, it should be treated with caution, because it will be very painful after being stung, and it will cause redness and swelling.

Human Stinging
Rectangle
Toxic to Humans

Northern Paper Wasp possesses a stinging defense mechanism. The sting delivers a cocktail of neurotoxins causing pain and limited tissue damage. While generally mild and localized, symptoms can include swelling and redness. Rarely, severe cases may experience extreme pain and necrosis, but these are typically non-lethal to humans.

Rectangle
Toxic to Animals

Northern Paper Wasp may inflict mild to severe consequences when its sting delivers venom to humans, pets like dogs and cats, or birds. Typically, adults utilize a sting for defense or prey capture, affecting both larger animals and small arthropods. Responses to the venom vary widely; while a human might experience pain and swelling or an allergic reaction, smaller animals could suffer more debilitating effects or even mortality from the encounter with northern Paper Wasp.

Does the Northern Paper Wasp sting humans?

Northern Paper Wasp may sting humans defensively if their nest is disturbed or they feel threatened. Stings typically occur when humans inadvertently encroach on northern Paper Wasp's territory. Stinging involves injecting venom through a sting apparatus, causing pain and potential allergic reactions in humans. Only female northern Paper Wasp are capable of stinging, as males lack a stinger. After stinging, northern Paper Wasp does not die and can sting multiple times.

Pollinator
Predators of Pests
Pollinator
Pollination Behavior Reason
Eat Pollen Or Nectar
Northern Paper Wasp is attracted to flowers primarily by their vivid colors and enticing smells. While adults feed on pollen, they inadvertently collect and transfer pollen grains between flowers, aiding in plant pollination. This incidental contact during feeding contributes significantly to the pollination process.
Predators of Pests
Purpose
Feed Itself, Feed Offspring
Diets
Caterpillars, Beetle Larvae
Northern Paper Wasp is a skilled hunter, primarily during its larval stage when the adults feed them protein-rich meals like caterpillars and beetle larvae. This predatory habit supports the growth of the young. Adults also consume small insects, aiding in pest control. A less-known fact is that northern Paper Wasp meticulously chews their prey before feeding it to their larvae.
