Hummingbird Hawk-Moth Invasion: UK Gardens See Record Sightings 2026

The hummingbird hawk-moth is creating a buzz across UK gardens, with a surge in sightings reported this summer. These remarkable insects, often mistaken for tiny birds, are drawing the attention of wildlife enthusiasts and gardeners alike.

Experts at Butterfly Conservation confirm that 2026 could be a bumper year for these migratory moths, thanks to warm southerly winds and heatwaves that have carried them from the Mediterranean and North Africa. Gardeners from Sussex to Scotland are sharing their awe-inspiring encounters on social media, describing the moth's distinctive hovering flight and rapid wingbeats.

What Is a Hummingbird Hawk-Moth?

The hummingbird hawk-moth (Macroglossum stellatarum) is a day-flying moth that resembles a hummingbird in both appearance and behavior. Its grey-brown body, orange hindwings, and long proboscis allow it to feed on nectar while hovering, much like its avian namesake. With wings beating up to 80 times per second, it creates a soft hum that adds to the illusion.

Unlike most moths, this species is active in daylight, making it easier for gardeners to spot. It is a master of long-distance migration, traveling thousands of miles from southern Europe and North Africa to reach the UK's cooler climate.

Why Are Sightings Increasing in UK Gardens?

Several factors are driving the recent influx of hummingbird hawk-moths to UK gardens:

• Warm southerly winds during heatwaves help propel moths northward.
• Drying food plants in Mediterranean breeding areas push moths to seek new habitats.
• Abundant nectar sources in UK gardens, such as buddleia and lavender, attract them.
• Climate change is making UK summers more hospitable for these insects.

Richard Harrington, an honorary fellow of the Royal Entomological Society, notes that the combination of warm weather and food scarcity in their native regions is a key driver. "It may also be that their food plants are drying out in their Mediterranean breeding areas," he explains.

Spotting a hummingbird hawk-moth is a thrilling experience, but it can be easy to confuse it with other insects. Here are key features to look for:

If you see a moth that seems to be a "grey lump with orange wings," as one Sussex resident described, you've likely encountered this incredible species. Its blurry wings in photos are a giveaway of its rapid wingbeat.
