European hornet

European hornet

Vespa crabro

A species of Hornets, Also known as Hornet

A famously ill-tempered pest, european hornet (Vespa crabro) is a species of hornet not generally aggressive unless it is provoked or disturbed in the presence of food. It makes its nest out of a chewed, papery substance, and it also chews food for its young. It is legally protected in some countries, such as Germany, where killing a hornet can result in large fines.

Species Status of European hornet
It is the largest eusocial wasp native to Europe. Unwarranted fear of V. crabro has often led to the destruction of nests, leading to the decline of the species, which is often locally threatened or even endangered.

Life Cycle of European hornet
Egg The egg stage is the initial phase where european hornet's life begins. Typically oval, the eggs are minuscule and lack distinct features. Color varies from transparent to a shade of white or pale yellow.
Larva As a larva, european hornet drastically differs from the adult, being worm-like in shape without wings, and with function limited to feeding and growth. The larva is often creamy white and moults several times.
Pupal Pupation marks a transitional period within a cocoon or cell. The pupa is immobile and undergoes significant internal changes. Size and shape evolve, hinting at adult features, but still encapsulated.
Adult Emerging from the pupa, the adult european hornet's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of European hornet Through Different Life Stages
The larvae of european hornet are typically found in sheltered aerial locales, often within hollow trees or in man-made structures where adult european hornet build nests from chewed wood pulp. To locate the larvae, one should search these nests, distinguishing them by their papery appearance. Adult european hornet, however, are commonly found around food sources such as flowers for nectar or other insects for prey. They are also attracted to human activities. Therefore, searching for adults may involve examining flowering gardens, orchards, and areas where human food consumption occurs. Pupae, transitioning within the nests, are in the same habitats as the larvae but inaccessible without nest deconstruction.
Rectangle
When is the Best Time to Observe European hornet
The best time to find european hornet is typically late spring through early fall when they are most active. Look for them during the day, as they are diurnal insects.
Rectangle
What is the Best Weather to Observe European hornet
European hornet are more likely to be found outdoors in warm and dry weather, as they do not prefer cold or rainy conditions.

How and Where Can You Find European hornet at Different Life Stages
Larva European hornet larvae are located inside the nest, usually within hexagonal cells made of wood fiber. To safely observe larvae, approach the nest cautiously and preferably at night when the european hornet are less active. Use protective clothing and avoid disturbing the nest.
Pupal Similar to larvae, european hornet pupae are found within the nest's cells. It is risky to attempt finding european hornet in this stage due to the protective nature of adult european hornet around their nest. If necessary for research, use the same precautions as for the larva stage.
Adult European hornet adults can be found by looking around flowers, under the eaves of buildings, or around other structures where they may build their nests. To attract them, set traps baited with food that is appealing to european hornet. Keep a safe distance from active nests to prevent being stung.

Toxic to Humans

European hornet's sting injects venom containing neurotoxins which can lead to pain, swelling, and redness. Symptoms generally include temporary discomfort, though severe cases can result in nausea or dizziness. Repeated stings might induce higher toxicity levels, potentially causing systemic effects in humans.

Rectangle
Toxic to Animals

European hornet's sting can cause discomfort and pain in animals such as humans, dogs, cats, and birds. Upon being stung, individuals may experience mild reactions such as localized pain, swelling, and redness. The venom is more of an irritant than a serious threat, and symptoms tend to resolve relatively quickly without lasting harm. While mammals, birds, and other insects like bees can be affected, they typically recover from the mild toxic effects without severe complications.

Rectangle
Is the European hornet Deadly?

European hornet has the potential to be fatal primarily due to venom-induced severe allergic reactions in stings. It can cause anaphylaxis, especially in vulnerable individuals such as children, the elderly, or those with previous allergic incidents. Prompt preventive measures and treatment for stings are vital to avoid potentially life-threatening outcomes.

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.
