How to identify a yellow-legged hornet

Contrary to popular belief, the invasive yellow-legged hornet (previously referred to as the Asian hornet) is not a large insect and is smaller than the European hornet, which is native to the UK. European hornets are yellow and brown, they are very large and make a loud sound when they fly. Yellow-legged hornets are more similar in size to wasps, but are much darker in colour than any native wasp. The image below shows the invasive yellow-legged hornet on the left and the native European hornet on the right.
