Are Blackjacket harmful to humans?

The female wasp has a long thick stinger connected to the poison gland. The main components of the venom are some alkaline substances, including histamine, serotonin, bradykinin, hyaluronidase, etc. When it is stung, it will shoot venom into the skin of the person, but the sting needle is not left in the leather suit. After a person is stung by a wasp, the stinged skin will immediately become red, swollen and painful, even with petechiae and skin necrosis. When the eye is stung, it will cause severe pain, tearing, redness and swelling, and may also cause corneal ulcers. In addition, systemic symptoms include dizziness, headache, vomiting, abdominal pain, diarrhea, restlessness, and increased blood pressure. The above symptoms usually disappear within a few hours to several days. In severe cases, drowsiness, systemic edema, oliguria, coma, hemolysis, myocarditis, hepatitis, acute renal failure and shock. Some people allergic to bee venom can manifest as urticaria, anaphylactic shock, etc.

Human Stinging
Rectangle
Toxic to Humans

Blackjacket's sting contains venom that can cause pain and inflammation in humans. The venom's toxins, aimed at defense and predation, can lead to neurotoxic effects. Mild encounters usually result in temporary discomfort, while severe stings might trigger more intense and lasting symptoms, but typically not life-threatening unless in cases of extreme envenomation or secondary complications.

Rectangle
Toxic to Animals

Blackjacket typically inflicts pain and discomfort on other animals it encounters, via a sting that can inject toxins. The intensity of the toxicity ranges from mild to severe, primarily affecting both humans and a variety of other animals, with adults being the toxic stage. When humans or mammals like dogs come into contact with blackjacket, they may experience significant pain, swelling, or even severe reactions requiring medical attention. Smaller animals such as rodents or insects could suffer fatal outcomes when exposed to the toxin.

Rectangle
Does the Blackjacket sting humans?

Blackjacket only stings when threatened or their nest is disturbed, primarily to defend their colony. Females possess the stinging capability; males don't. The sting injects venom, causing pain and potential allergic reactions in humans. Stinging has no adverse effects on blackjacket as their stingers are not barbed unlike those of honeybees.

Pollination Behavior Reason
Eat Pollen Or Nectar
Blackjacket assists in pollination primarily through foraging for food. Attracted by the vivid colors and enticing scents of flowers, it consumes pollen and nectar. While feeding, pollen grains stick to its body and are inadvertently transferred to other flowers, facilitating cross-pollination.

European potter wasp
European potter wasp

The European potter wasp or European tube wasp (Ancistrocerus gazella) is a species of potter wasp. As an imago (adult), the female collects as many as 20 caterpillars for each nest, which consists of a single cell. Her larval offspring then feed on these inside the nest, which is sealed with mud arranged by her. As adults, they eat nectar and aphid honeydew. Males cannot sting, and the sting of a female is not painful. They can be found on windows, foraging for nectar on flowers, or searching out small cracks or holes in which to nest.
