Larva Larvae of yellow paper wasp are typically found in the nests constructed by the adults. Seek out nest sites, which could be in crevices or in the ground, to observe larvae.
Pupal To find pupal yellow paper wasp, look within the nests where larvae were raised. The pupae will be immobile and often found in protected cells within the nest structure.
Adult Adult yellow paper wasp can be found foraging for food, on flowers, or around human habitations. Search for adults in areas with plenty of floral resources or near food sources like garbage bins where they may come to scavenge.

Are Yellow paper wasp 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

Yellow paper wasp is a wasp species whose sting contains neurotoxins that can disrupt human nervous system functions. The adult's primary defense mechanism is its sting, employed during predation or defense. Risks to humans vary from mild irritation to severe neurological symptoms. Long-term effects are rarely serious but can include persistent pain and neurological complications.

Rectangle
Toxic to Animals

Yellow paper wasp can deliver venom via a sting, which ranges from mild to severe in its effects. For humans, stings might cause pain, swelling, and, in rare cases, severe reactions. Smaller mammals such as dogs and cats may experience intense pain and could be more seriously affected due to their size. The adult form of yellow paper wasp is capable of envenomation, and although the purpose is typically defensive, accidental encounters can result in poisoning.

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.
