Appearance of the Asian hornet

2. Color: The Asian hornet has a dark body that is almost black, with a yellow stripe at the back of the abdomen. Its face is orange-yellow.
3. Wings: The wings are dark and almost smoky gray.
4. Legs: The hornet has yellow tips on its legs, which is a striking distinguishing feature when it flies.
5. Nest: The Asian hornet's nest is often high in the trees, but it can also be found underground or in tall structures such as chimneys. It has an oval shape and is made of chewed wood, which gives the hornet a papery texture.
It is important to distinguish the Asian hornet from the European hornet (Vespa crabro), which is more harmless and a natural part of the European fauna.

How dangerous is the Asian hornet?
The Asian hornet (Vespa velutina) is a predatory insect that originated in Asia and has spread in recent years to various parts of Europe, including France and now also Switzerland and in Bretzwil. Although it poses a threat to honey bees and native biodiversity, it is generally no more dangerous to humans than other wasp species. Nevertheless, there are some aspects to be aware of:
1. Threat to honey bees: The Asian hornet preys on honey bees, threatening native bee populations. A decline in bees can have a negative impact on pollination and thus on local flora and agricultural production.
2. Stings: As with other wasp and hornet species, the stings of the Asian hornet can also be painful. For most people, the stings are unpleasant but not dangerous. However, people who are allergic to wasp or hornet stings can suffer a severe allergic reaction, which in the worst case can lead to anaphylactic shock.
3. Aggressiveness: Although the Asian hornet is not necessarily more aggressive towards humans than other wasp species, it can become aggressive if it feels threatened, especially near its nest.
4. Ecological effects: Apart from the direct effects on honey bees, the spread of the Asian hornet can also disturb the ecological balance by affecting the populations of other insects.
To avoid confusion, it is important to note the distinction between the Asian hornet and the larger Asian giant hornet (*Vespa mandarinia*), which is often referred to as the "killer hornet." The giant hornet poses a potentially greater danger to humans due to its more powerful venom and the size of its sting.
