A hornet which can kill up to 50 bees a day has been found in Sark in the Channel Islands for the first time.
The Asian hornet has been positively identified by States of Guernsey experts and sent for genetic testing.
The public are advised to photograph and report the "aggressive predator" of honey bees if spotted.
The hornet found in Sark measured 22mm (just under 1in) and beekeepers in the Channel Islands have been notified.

The Guernsey Beekeeping Association has advised its members to increase vigilance and monitoring of bee hives through the use of hornet traps.
Anyone spotting what they believe to be Asian hornet is recommended to watch it long enough to determine the direction of travel as this may be helpful in finding a nest site.
As with wasps and bees, the hornets have a painful sting so people should avoid direct contact and never attempt to disturb a hornets' nest.
