Hemaris, commonly known as clearwing moths or hummingbird moths, is a genus of diurnal and crepuscular insects belonging to the family Sphingidae, which includes sphinx moths. The name Hemaris is derived from the Greek word "hēmeros," meaning day, further emphasizing their preference for daytime activity.
These moths are characterized by their hawk-like swift movements and the transparent or glassy appearance of their wings, which gives them the nickname "clearwings." With a stout body covered in dense, often colorful hairs, these moths closely resemble hummingbirds in their size and manner of flight. Typically, they display a mix of brown, black, and yellow markings along their bodies and wings.
Hemaris moths are known for their effective mimicry of bumblebees or hoverflies, as they hover effortlessly in front of various flowers while probing for nectar using their long proboscis. This tactile organ, reminiscent of a straw, allows them to feed on the nectar of numerous flowering plants. Consequently, they play a vital role in pollination, aiding in the transfer of pollen between plants.
Found across various regions globally, including North America, Europe, and Asia, Hemaris moths can be seen in a variety of habitats, including open woodlands, gardens, and meadows. Despite their similarity to hummingbirds, these moths are entirely unrelated, representing a remarkable convergence of evolutionary traits between insects and birds.
