A small primary nest of Asian hornets in was reported to the National Bee Unit (NBU) on Thursday, June 22.
An NBU inspector reportedly investigated the sighting and collected samples, which have been sent for analysis.
Traps have been set for hornets returning to the nest site, and follow up activities will take place to raise awareness.
NBU said this is the earliest date in the season that a nest has ever been found in Great Britain.
Nests have previously been reported in the autumn, when insects are more visible as the population of the nest increases to its maximum.
The Asian hornet is smaller than the European hornet and is a highly aggressive predator of native insects. While it poses no greater risk to human health than a bee, they can cause incredible damage to honeybee colonies and other pollinating insects.
