The hornet is Britain’s largest social wasp measuring up to 35mm long – its size alone ensures it cannot be mistaken for any other wasp. Like the common wasp, it is striped but, instead of being black and yellow, it has chestnut-brown and yellowy-orange stripes. The head consists of stout antennae, two ‘c’ shaped eyes and three round simple eyes.
Hornets get confused by lights at night and may fly into windows. If this happens, turn off the light for a few minutes so the hornet can re-orientate itself.
