Asian Hornets (Vespa Velutina) were found this summer in New Alresford and Brockenhurst. It pays to be observant and aware of this species. There are many good websites with information about what they look like and what to do if you find one for example at http://www.nonnativespecies.org/alerts/index.cfm?id=4.
If you see one this Autumn (or next Summer) report it straight away to firstname.lastname@example.org. Information about a new app can be found here: https://www.gov.uk/government/news/new-app-to-report-asian-hornet-sightings
