This either causes the hornet to lose its grip, or the bee raises its sting and tussles until the hornet gives up.</p><p>"The buff-tailed bumblebee did not evolve alongside Asian hornets – their native predators include badgers, birds, wasps and spiders – so O'Shea-Wheller describes this as 'an evolutionary coincidence'. </p><p>" 'This defence that already works against their natural predators also works against the hornets,' he says. European honeybees, on the other hand, have no such 'co-evolved system' to protect themselves from these new predators." </p><p><a href="https://www.bbc.com/future/article/20240206-the-bees-learning-to-fight-off-invasive-hornets" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://www.</span><span class="ellipsis">bbc.com/future/article/2024020</span><span class="invisible">6-the-bees-learning-to-fight-off-invasive-hornets</span></a> </p><p><a href="https://kolektiva.social/tags/BeeHugger" class="mention hashtag" rel="tag">#<span>BeeHugger</span></a> <a href="https://kolektiva.social/tags/BeeHuggah" class="mention hashtag" rel="tag">#<span>BeeHuggah</span></a> <a href="https://kolektiva.social/tags/Bumblebees" class="mention hashtag" rel="tag">#<span>Bumblebees</span></a></p>
