Yellow-legged (Asian) Hornet update.
Yorkshire beekeepers have just received an update that a nest of yellow-legged (Asian) hornets has been discovered just south of Malton in North Yorkshire. Most of the incursions into the UK to date have been around ports or easily linked to imports, so a nest being found 60ft up a lime tree in North Yorkshire is extremely bad news.
Hopefully you've seen some of the media coverage about this particular hornet. It's an invasive species that arrived in France in 2004 and has been steadily working its way across the continent. Being an imported species these hornets have no natural predators in Europe, so they spread unchecked and have an absolutely devastating impact on local insect populations. Although a lot of the coverage has been based around "saving the bees" these critters will eat pretty much anything and everything smaller than them; moths, butterflies, wasps, bees, all the things we need to pollinate our food crops.
BBKA have a series of resources on how to identify YLH here: https://www.bbka.org.uk/identify-report-asian-hornet, in particular how to tell them apart from common wasps and the mostly harmless native European hornet.
The National Bee Unit policy at the moment is one of trace and destroy, so if you see one of these nasties please get a picture of it (a picture is 100% needed to sift through the huge number of false-positive reports) and submit it through the 'Asian Hornet Watch' app, which is on all the usual app stores.
How to identify if the insect in front of you is a 'Yellow-Legged Asian Hornet' and details of how to report any sightings.
