Why Do Wasps Shake Their Bum?

Wasps are omnivorous and feed on both insects, fruit, and sweet substances such as nectar and honey. They play a critical role in pollinating plants and crops and are an important food source for humans. However, many people confuse wasps with bees because they are both insects, but there are several key differences. Bees are herbivorous and primarily feed on flowers. Their hind legs are flattened for collecting and transporting pollen. Wasps, on the other hand, are predatory and will feed on a wide variety of prey, including insects, fruits, and sugary substances like nectar and honey. They are also known to build papery nests in trees and roof eaves.

The Flicking Wasps Wings

The reason why wasps flick their wings is not fully understood. Some entomologists believe that it may be a form of thermoregulation. As the wasp flaps its wings it can change the temperature of different parts of its body. For example, the thorax of the wasp is warmer than the abdomen. When the wasp flaps its wings it can redistribute this heat so that it is evenly distributed throughout the insect’s body. It is also possible that the wasps flick their wings to communicate with one another. Just as bees use their antennae to communicate, wasps can use the pulsing of their wings to broadcast a special chemical called the nasonov pheromone.

Wasps are particularly active in spring and early summer, when they are looking for protein foods like meat and fish. To keep wasps away from your yard, remove any food sources, especially sugary ones, and cover drinks or other open containers outside. You can also try spraying your yard with a mixture of clove, geranium, and citronella oil to deter wasps and other pests.
