The UK is experiencing a unique and captivating phenomenon this summer: an abundance of hummingbird hawk-moths. These fascinating creatures, with their distinctive grey furry bodies and bright orange wings, have been spotted in gardens across the country, captivating the attention of nature enthusiasts and social media users alike.
What makes this year's sighting particularly remarkable is the significant increase in their presence. In 2021, there were only eight recorded sightings of the hummingbird hawk-moth in the UK, according to the National Trust. However, this summer has been dubbed a "hummingbird hawk-moth summer" by the Wildlife Trust, indicating a substantial rise in their numbers.
The hummingbird hawk-moth, despite its small size (up to 6cm long), is often mistaken for a tiny bird due to its hovering flight and distinctive appearance. Its wings flutter so rapidly (up to 80 times per second) that it creates an audible hum, resembling the flight of a hummingbird, for which it is named. This species, native to the Americas, shares the hummingbird's rapid wing beats and ability to fly up to 12 miles per hour.
The surge in hummingbird hawk-moth sightings can be attributed to several factors. Firstly, the hot weather and strong winds across Europe have played a crucial role. These conditions have facilitated the migration of these moths from Southern Europe to the UK, allowing them to travel higher and cover more ground.
Additionally, the UK is currently experiencing a once-in-a-decade "painted lady summer," with a significant influx of migratory butterflies arriving and breeding in the country. Conservationists attribute this increase in butterfly numbers to the warmer weather, which has also contributed to the rise in hummingbird hawk-moth sightings.
The hummingbird hawk-moth's preference for flowering plants, such as valerian and buddleia, makes gardens an ideal habitat. Vicki Hird, the Wildlife Trust's Strategic Lead on Agriculture, advises gardeners to cultivate these plants to attract these moths. Bedstraw is also essential, as it is the primary food source for the caterpillars of the hummingbird hawk-moth.
This summer's hummingbird hawk-moth sightings offer a captivating glimpse into the wonders of nature. As these moths continue to grace our gardens, they remind us of the intricate relationships between species and the impact of environmental factors on their behavior and distribution. It's a reminder of the importance of preserving diverse ecosystems and the delicate balance that sustains our natural world.
