What Are Red Wasps?
Belonging to the family Vespidae (paper wasps), they are a species of wasp native to the United States. They are spread out over New York, Florida West to Kansas and Texas.
They are scientifically called Polistes carolina or Polistes rubiginosa.
Red wasps grow up to an inch long with six legs and a pair of frail wings that are black or purple in color. The wasps are between bright red and orange in color, often identified by the large nests they build.
These are social wasps that build their large, umbrella-shaped nests in hidden areas.
These species build nests that can house up to 5,000 wasps in brood cells. These wasps are abundant in the garden in summer when they are building nests for the breeding season.
Red Wasp Lifecycle
In a red wasp colony, life cycles occur in four phases:
This takes place in the spring season when young females start building new nests.
There is a queen wasp, larger in size than others, who is known as the foundress. She is the one who starts building the wasp nest.
The nests are built individually or with several foundresses working together.
At this phase, the foundress lays only female wasps, who become her workers. This time is taken up for maintaining the nest, foraging, and taking care of the new wasp larvae by adult wasps.
The reproductive phase lasts from the first hatching of the new larva to the colony declining. Adults mate to lay eggs, and the larvae start to grow.
As they become bigger and stronger, they spread out of the nest and start to create their own.
Decline and Rebirth
This is the final stage of a read wasp’s life cycle consisting of colony decline. The new wasps have all flown out to make their own nests, and the old colony declines and finally perishes.
What Do They Eat?
Red wasps are omnivores that feed on a lot of organic materials. Their diet includes nectar, fruits, honey, and small insects. These wasps are also attracted to leftover food, meat in particular.
The wasp larva feeds on caterpillars and other insects that are chopped up by the adults.
Nectar is also an important part of the wasps’ diet. They are often attracted to bright flowers, goldenrod being a favorite.
What Eats Red Wasps?
In their natural habitat, there are a lot of creatures that feed on them. The bright colors of these wasps make them an easy target for a lot of creatures.
Birds are the most common predators of solitary wasps.
When wasps are flying alone, the birds can easily swoop in to hunt them, which is difficult for social wasps in groups.
In the case of red wasps, a bird will try to hunt them when they are away from the nests.
The common birds to hunt wasps are sparrows, starlings, and mockingbirds, among others.
Invertebrates and Other Insects
Large insects like dragonflies, centipedes, spiders, and praying mantes are common wasp predators.
They can attack the wasp mid-air and also hunt them among tree branches and flowers.
Amphibians and Reptiles
One of the common reptiles that feed on wasps are geckos and small lizards. Insects like toads, frogs, and salamanders also make their way to the wasps’ nests to feed on the larvae.
Large mammals can sometimes feed on red wasps if they are hungry or stumble on their nests.
Black bears are the most common predators of these wasps, usually going after the nests in search of honey. Small mammals like badgers, weasels, and mice also feed on wasps.
