When you think of the word hovering, most people think of a hummingbird because of its flight traits. The hummingbird hawk moth, also known as the Macroglossum Stellatarum has a flight pattern very similar to the hummingbird, which is an excellent hovering animal.
These sphingid moths are found in Europe, North Africa, and Asia, for their warmer climates, but do not last long during the winter. Along with the hovering wing aspect of the moth, the Macroglossum Stellatarum also has a long, straw-like mouth, similar to the hummingbird’s long beak, which is used to suck nectar from flowers. This straw-like mouth is called a proboscis.
Some features that allow this moth to fly effectively are its narrow wings and aerodynamic body. The moth’s narrow wings are able to flap rapidly, sustaining a steady, leveled flight, or hover as it retrieves nectar from flowers. Size of the wingspan can vary from a small 40mm to a larger 10 cm. The hawk moth’s aerodynamic body allows for fast cutting motions used to circle around a patch of flowers when collecting nectar. This phenomenal flyer is able to reach speeds of 12 mph when flying instead of hover.
The video above shows the moth’s amazing stability when it hovers around flowers.
