Asian Hornet

Look Out For Asian Hornets

What Do They Look Like? 

  • Slightly smaller than native European hornet. Asian Hornet queens are up to 3 cm in length; workers up to 25 mm
  • Dark abdomen, 4th segment yellow
  • Bright yellow tips to legs (native hornet dark)
  • Entirely brown or black thorax (native hornet more orange).

During August the wasps will begin their annual search for a way into your beehives with the intention of stealing honey. Their presence is usually pretty obvious but, these days, beekeepers should also be on the lookout for Asian Hornets as well. The presence of Asian Hornets may not be quite as obvious. They may be ‘hawking’ in front of the hive or ‘skulking’ behind or under it to seize tired or unwary bees which they will butcher before taking the thorax (which is high in protein) back to feed to their larvae.

We hope that Asian Hornets do not get into this country but we must all be on our guard – the earlier the presence of Asian Hornets is detected the sooner action can be taken to find and destroy the nest.
