The summer of 2023 has brought an unexpected and captivating phenomenon to the UK's gardens and social media feeds: an influx of hummingbird hawk-moths. These unique creatures, with their distinctive grey fur and vibrant orange wings, have sparked curiosity and wonder among nature enthusiasts and casual observers alike.
The Rise of the Hummingbird Hawk-Moth
In a typical year, sightings of these moths are relatively rare, with only eight recorded in the UK in 2021. However, this year has been exceptional, with reports of numerous sightings across the country. The National Trust has even dubbed it a "hummingbird hawk-moth summer."
One of the most fascinating aspects of these moths is their resemblance to tiny birds. Despite their small size, growing up to just 6cm in length, their rapid wing movement creates an audible hum, a characteristic that sets them apart from other moths and gives them their name.
A Bird-Like Moth
The hummingbird hawk-moth's wings beat at an astonishing rate of up to 80 times per second, faster than their namesake, the hummingbird. This incredible speed allows them to achieve impressive flight speeds of up to 12 miles per hour. It's a remarkable adaptation that has earned them their unique place in the insect world.
So, what has led to this sudden increase in sightings? Experts believe that the hot weather and strong winds across Europe have played a significant role. According to Vicki Hird, Strategic Lead on Agriculture at the Wildlife Trust, these windy conditions can "push" the moths across the continent, bringing them to the UK in larger numbers. Additionally, the drought in Europe may have impacted their food sources, prompting them to seek sustenance in the UK's gardens.
Weather and Migration
This year's weather patterns have also contributed to another remarkable migration event: the "painted lady summer." Conservationists have reported a surge in the number of migratory butterflies, known as painted ladies, arriving and breeding in the UK. Warmer temperatures have been cited as a key factor in this phenomenon.
Attracting Visitors to Your Garden
If you're hoping to spot a hummingbird hawk-moth in your garden, Vicki Hird recommends planting flowering plants such as valerian and buddleia, which are known to attract these moths. Additionally, the species requires bedstraw for their caterpillars' diet, so ensuring a supply of this plant can encourage their presence.
A Deeper Look
The arrival of these moths and butterflies highlights the intricate relationship between weather patterns, migration, and the availability of food sources. It serves as a reminder of the delicate balance of nature and the impact that even subtle changes in our environment can have on wildlife.
Conclusion
The hummingbird hawk-moth's unexpected appearance this summer has provided a fascinating insight into the wonders of nature. It's a reminder to appreciate the beauty and diversity that exists right in our backyards. So, keep an eye out for these remarkable creatures and the many other fascinating species that call our gardens home.
