Turned out it wasn't an Asian Hornet (AH) but here's the story.
I had a pm on this forum yesterday from a beek I know who had lost my contact details. Message said:
"Hi
Had a phone call from an ex-beekeeper friend in Mary Tavy.
He has had a beekeeper from South Wales staying at Lydford, who was very concerned and claims that he saw Asian Hornets in a yellow shrub outside the National Trust teashop at Cotehele... taking honey bees.
Quite why the message was passed to me I do not know.
No photo or sample, but chap was convinced they were Asian Hornets
Thought your group may be interested... have sent email to the alien species lot!
Good Luck"
As a coordinator for a newly formed Asian Hornet Action Team, I started phoning down my contact list and the first two volunteers that I spoke to said they would stop what they were doing and meet me at Cotehele, a National Trust property in Calstock, Cornwall. We met up by the teashop and found the shrub that was attracting all the insects - it was Pileostegia viburnoides (common name "Climbing Hydrangea"). The plants were absolutely covered in all sorts of pollinators, including: honey bees, wasps, several types of bumble bee (including queens), hover flies and other flies.
Feeding on these were European Hornets(EH). We saw EHs take a wasp and a honeybee. The EHs behaved just like an Asian Hornet (AH) in that they took their prey to a perch and bit the head off, possible more, before flying off with the remains. The one difference appeared to be that the EH took a static prey feeding on the plant whereas we are informed the AH takes its prey in the air. Trying to follow the flight of the hornet, as they are doing in Jersey, to track the hornets to their nest, was very difficult.
The conclusion that we came to after watching for half an hour was that what had been seen by the Welsh Beekeeper was a European Hornet behaving like an Asian Hornet and the speed of flight meant that a casual watcher from the teashop tables would not realise that it was the native hornet and not the invasive species.
How did we feel at the end of our first call-out? Well, relieved in a sense that it was a false alarm. I was personally grateful that the first people I called to assist dropped what they were doing and drove out to Calstock with cameras and nets ready for action.
Today, I reported our findings to the local SBI and sent him photos of what we had seen. He checked with the RBI who decided that he should put up a monitoring trap (which a forum member has offered to check daily).
The big lesson that came out of this is that some beekeepers still don't know how to identify Asian Hornets, despite all the efforts over the last two years by the NBU. Come on guys, wake up!
