Asian Hornets are a non-native species of hornet that can cause problems for our native bees.
Asian hornet facts
- Asian hornets (Vespa velutina nigrithorax) are slightly smaller than native European hornets and look like large black wasps with orange face and yellow legs:
- An Asian hornet queen is up to 30mm long; workers are up to 25mm long.
- Asian hornets are dark brown or black with a velvety body and the abdomen is almost entirely black except for a yellow fourth abdominal segment. Legs are brown with yellow ends.
- The Asian hornet is active mainly between April and November (peak August/September) and is inactive over the winter.
- A single Asian hornet can kill 50 bees a day, with a nest containing up to 6,000 workers and up to 350 queens.
- In Jersey, France and large areas of Western Europe they are stripping the environment bare of insects before moving on to prey on managed honeybee colonies.
