The Asian Yellow-Legged Hornet, Vespa velutina, is a serious threat to bees and beekeeping in Britain, given its predatory nature and the fact that a large nest may contain 10-12,000 hungry insects.  It also poses a secondary threat to birds and bats, as it has the ability to consume massive numbers of their prey, while themselves being virtually immune from attack by any of our native species.  PLEASE LEARN ABOUT THIS DANGEROUS PEST and look out for news about it, preferably by checking the news page on https://friendsofthebees.org and don't rely on newspapers, which regularly feature pictures of the wrong species. There is an Android app called "Asian Hornet Watch" that makes identification and reporting easy: this is an invasive non-native species that must be reported to http://www.brc.ac.uk/risc/alert.php?species=asian_hornet  If you use FaceBook, look for my page "Defending Britain Against the Asian Hornet" for news and updates.
