Murder hornets spotted in North America caused a panic in 2021. Here's what they really are and how they got here ⬇️
Murder hornets, also known as Asian giant hornets , are the world's largest wasps. These hornets naturally occur in Asia, but humans have accidentally introduced them into North America where they pose a threat to native wildlife, as they kill other insects, including smaller wasps and bees.
Murder hornets can kill about 30,000 individuals in a bee colony during a"slaughter" attack. After most of the adult bees are dead, the hornets focus on the bee larvae and pupae — bees' dormant form between larvae and adults. Murder hornets steal the bee larvae and pupae and take them back to their nest to feed to their own larvae, according to the University of Florida .
More murder hornets were reported in Washington and Canada in 2020 and 2021. According to a statement released by the WSDA, one dead hornet found near Marysville, Washington, in June 2021 appeared to be unrelated to any of the previously discovered hornets and was therefore from a separate introduction. Life cycle Murder hornets are social insects that live together in colonies or nests. All murder hornet colonies begin in spring with one mated queen.
