The Hummingbird Hawk-moth is a large, day-flying moth which hovers like a hummingbird as it uses its long "proboscis" (tongue) to drink nectar from flowers.
It is quite plain from above when at rest and well-camouflaged but it has orange under-wings briefly visible when hovering in flight.
UK flight time: Summer (mainly migrant).
Wingspan: 40-50mm.
Flying with tongue out while feeding.
They are native to much of temperate Eurasia, from Portugal (including the Azores) and Northwest Africa to Japan.
The long tongue allows them to access nectar in tubular flowers that other moths/insects can't reach such as petunia
and raspberry sage, above.
When hovering, like its namesake hummingbird, the wings move rapidly but the head and body are still.
The fish tail (different individual than that hovering in the row earlier).
Have you seen that it can flash violet highlights in its tail? It can also have a face pattern in the tail.
