Yes, the hummingbird moth, particularly species like the hummingbird clearwing (Hemaris thysbe) and the snowberry clearwing (Hemaris diffinis), is known for its nocturnal activity. These moths resemble hummingbirds in their appearance and behavior, often hovering in front of flowers to feed on nectar. They are indeed attracted to strong, sweet scents, which helps them locate flowers, especially those that are rich in nectar.
Hummingbird moths play an important role in pollination, much like their avian counterparts, and their nighttime activity makes them especially fascinating to observe. They are commonly found in gardens and fields where their preferred flowering plants bloom, such as phlox, lilacs, and certain types of flowers in the evening or night.
