Two pairs of southern giant hornets, also known as “murder hornets,” have been found in northern Spain for the first time. Researchers are now searching for the nest of these invasive insects, which are known to kill off beehives. The hornets, which originate from Asia, have been spotted in the city of Siero in both March 2022 and October 2023. The scientists involved in the study believe that the hornets likely first arrived in Europe on a cargo ship. The discovery of these hornets in Spain could have a significant impact on the local ecosystem, as they aggressively hunt native hornets, bees, butterflies, moths, and flies. The researchers are working to locate and destroy the nest of the southern giant hornets before their population grows and further disrupts the ecosystem. The genetic testing and analysis of the captured hornets have confirmed the species’ identity, and experts are now focusing on mitigation efforts such as education and alerting local authorities. The detection of these hornets in Spain suggests that more may be on the way, highlighting the importance of strengthening quarantines and check measures in port cities to prevent the introduction of invasive species.
