Asian giant hornet: A giant to respect at a safe distance

The Asian giant hornet is one of the largest and most awe-inspiring wasps in the world. It can reach five centimetres long and flies like a small bomber. With this animal we keep our distance and show it respect. Let's look at why it matters and at the remarkable contest between it and honeybees.

Its body

The Asian giant hornet can grow to five centimetres, with a sting about six millimetres long. Its aggression peaks in autumn, when it is defending its nest — the most dangerous season, so always keep away. Its strong mouthparts can crush other insects.

For all its danger, it plays an important role in the forest: it preys on many pest insects. So between people and hornets, the most important rule is quite simply "keep a safe distance".

Its life and its story with the bees

The hornet feeds on other insects, especially honeybees — a handful of hornets can destroy a hive. But Japan's native honeybees have evolved a remarkable defence: when a scout hornet appears, the bees swarm over it, form a tight ball and vibrate, heating the centre to nearly 50 degrees, cooking the hornet alive. That "hot ball" battle is one of the classic moments of nature.

A note for grown-ups

If you see a hornet, move away with your child and do not provoke it. You can tell the story of the bees heating the hornet, and add a gentle reminder: even powerful attacks are beaten by cleverness and teamwork — and for people, the wisest response is simply to stay well away.
