The hornet moth or hornet clearwing (Sesia apiformis) is a large moth native to Europe and the Middle East and has been introduced to North America. [1] Its protective coloration is an example of Batesian mimicry, as its similarity to a hornet makes it unappealing to predators.
The moth's wings lack the large amount of scales found in most other lepidopterans, particularly in the centralized regions, making them appear clear. It loses the scales on its wings early after the pupa stage by its highly active flight tendencies. Hemaris diffinis is an excellent bumblebee mimic.
As it begins to fly, scales fall off leaving a mostly clear wing with reddish-brown borders and veins. [2] The width and shape of the border as well as the patterning of the veins vary between individuals. [5] The moth beats its wings quite rapidly and has a wingspan of 4 to 5.5 centimetres (1.6 to 2.2 in).
