The European hornet is not a native species to the Balearic Islands. Although its invasive potential in the Balearics is unknown, it is being targeted as a cautionary measure. It seriously affects beekeeping activities given its preference for feeding on honeybees. Hunting pressure can lead to bees ceasing all gathering activities and thus represents a danger to their survival.
