Bumblebee Moths and Hummingbird Moths
Hemaris diffinis resembles bumble bees and Hemaris thysbe vaguely resembles hummingbirds in flight. Hemaris diffinis, the snowberry clearwing, is a moth of the order Lepidoptera, family Sphingidae, and is sometimes called "hummingbird moth" or "flying lobster".
Hemaris thysbe, the hummingbird clearwing, is a moth of the family Sphingidae (hawkmoths). Coloration varies between individuals, but typically the moth is olive green and burgundy on its back, and white or yellow and burgundy on the underside. Its wings are transparent with a reddish-brown border. It has light-colored legs, which combined with the lack of striping on the underside is diagnostic. Beating its wings rapidly, H. thysbe hovers to collect nectar from a variety of flowers. The combination of its appearance and its behavior commonly leads to it being confused with a hummingbird or bumblebee.
