Wasps

Wasps are insects belonging to the order Hymenoptera, which also includes bees and ants. They are known for their distinctive yellow and black markings and their ability to sting. Wasps are found in virtually every part of the world except for the polar regions.

Classification

Wasps are divided into two primary subgroups: the Parasitica, which are mostly parasitic, and the Aculeata, which are the stinging wasps. The Parasitica are further divided into several superfamilies, including the Ichneumonoidea, Chalcidoidea, and Cynipoidea. The Aculeata include the families Vespidae, Sphecidae, and Pompilidae, among others.

Characteristics

Wasps range in size from the tiny fairyfly to the large tarantula hawk wasp. They have a slender body with a narrow waist, and most species have two pairs of wings. The females of many species have a stinger, which they can use to defend themselves or to paralyze their prey.

Behavior

Wasps are known for their social behavior. Many species live in colonies, where they build nests and care for their young. Some species, such as the yellowjacket and the hornet, are known for their aggressive behavior when their nest is threatened.

Role in Ecosystem

Wasps play a crucial role in the ecosystem. They are predators of many pest insects, helping to control their populations. Some species are also important pollinators.

Human Interaction

While wasps are often seen as pests due to their stings, they are generally not aggressive unless provoked. Some species, such as the paper wasp, are even used in biological control programs to help control pest insects.
