Can anyone identify this please - it moved so fast that I had to slow the video right down to see it - you probably can't tell but it was reallly very big (unforturnately I don't have David Attenborough's camera crew!) and I didn't want to get too close! Surrey UK
Well done for having a go with the video.
It is a bit of a challenge to see, but I am fairly sure it is a European hornet, Vespa crabro.
(I'm looking at its brown front, black middle, yellow back-end; and correct size.)
Thanks Mike. I think you must be right. It's buzz was extremely loud- it dwarfed all the bumblebees that were flying around and from the video had a very yellow face- I found this I the web link you posted:
Vespa crabro vexator Harris, 1776. A European hornet found in southern counties of England, and continental Europe. This subspecies can be distinguished from the Common European hornet as V. crabro vexator has a yellow head
The thing that struck me as I looked at it by eye was its red/ orange colour which it shows in the photos on the link. I have only seen one flying in and out so I'm assuming this could be the queen? I'm assuming there's only one as it flies out then comes back again with no others having flown in or out in the meantime!
Should I get this moved- worried about the kids getting stung- not to mention myself!
Well done for looking into it further.
If you go to the 'Images' tab on this page, you'll see the queen and worker side by side - it is easy to tell the difference - http://www.nhm.ac.uk/nature-online/species-of-the-day/collections/our-collections/vespa-crabro/
In my experience, hornets are similar to wasps in terms of aggressiveness - and they won't sting you just for the sake of it, only if provoked. I'd go along with the opinion expressed here - http://www.insectstings.co.uk/hornets/ and here - http://www.vespa-crabro.de/hornet_vespa_crabro_vexator.htm
So in your case, personally, if you're not going to be interfering with their nest or the insects themselves when they are near the nest or busy hunting, I'd leave them alone. But your situation may warrant removal - if you have young kids, if you or family have known allergy to wasp stings, or if you are disposed to hate big buzzing things, or if you know your neighbours will complain. ...In which case, get rid of the nest while there is still just the one hornet.
Here's some advice - http://www.wikihow.com/Get-Rid-of-Hornets
But in your case, assuming there's no other way tothe nest itself, you may be able simply to block the access crack shown in your video.
