Asian Hornet sightings, identification and reporting

The Asian Hornet (Vespa velutina) is a highly aggressive predator of native insects and poses a significant threat to honey bees and other pollinators. It also feeds on other insects, fruit and flowers.

How to identify the Asian Hornet (Vespa velutina)

You can identify Asian Hornets by their:

  • velvety dark/dark brown mid-body
  • black head with an orange/yellow face
  • brown segments on the rear bordered with a fine yellow band
  • brown upper leg segment with yellow lower segments

Natural Environment staff, together with numerous volunteers, will be monitoring reported sightings and tracking hornets back to their nests, where they can be destroyed.
