Auckland Residents Urged to Report Yellow-Legged Hornet Sightings

Biosecurity New Zealand has issued an urgent call for residents in Auckland to report any sightings of yellow-legged hornets following the discovery of a queen hornet on the North Shore. On October 17, 2023, biosecurity officers successfully removed a nest of yellow-legged hornets, known scientifically as Vespa velutina, in the suburb of Glenfield. This species had not previously been recorded in New Zealand, raising significant concerns about its potential impact on local honey and wild bee populations.

The presence of the yellow-legged hornet poses a notable biosecurity risk. According to Mike Inglis, North Commissioner at Biosecurity New Zealand, the nest was still in its early stages of formation, indicating that the immediate threat of a fully established colony has been mitigated. Nevertheless, with the summer season approaching, there is an increased risk that any undetected nests could further threaten local ecosystems.

Inglis emphasized the importance of vigilance among Auckland residents. “This is the first time we’ve found a queen yellow-legged hornet in New Zealand,” he stated, highlighting the unprecedented nature of this discovery. The yellow-legged hornet is known for its aggressive behavior and has the potential to disrupt local bee populations, which are vital for pollination and maintaining biodiversity.

Biosecurity New Zealand is urging residents to familiarize themselves with the appearance of the yellow-legged hornet to aid in early detection. The hornet is identifiable by its distinctive yellow legs and brown body, and it can grow to approximately 3 centimeters in length. In light of this new threat, authorities are calling for community cooperation to report any sightings immediately.

The removal of the hornet nest is a proactive measure aimed at preventing the establishment of a larger population, which could have dire consequences for local agriculture and wildlife. Residents are encouraged to report any suspected hornet sightings to Biosecurity New Zealand, which has established protocols for monitoring and managing such invasive species.

As the situation evolves, Biosecurity New Zealand continues to monitor the area closely. The agency remains committed to safeguarding New Zealand’s unique environment and agricultural interests from invasive pests. Local communities play a vital role in this effort, and prompt reporting of any suspicious insect activity is essential to maintaining biosecurity in the region.
