Hemaris diffinis, commonly known as the Snowberry Clearwing Moth, is a small hummingbird mimic with a wingspan of 1.5 to 2 inches. It features a distinctive clear wing pattern, yellow and black body, and is known for hovering flight. Found in gardens and woodlands across North America, it feeds on nectar and plays a role in pollination.

Hemaris diffinis, commonly known as the Snowberry Clearwing, is native to North America. Its geographical distribution spans from Alaska and the Yukon in the north, across Canada, and throughout the United States, with the exception of the southernmost states. It is especially prevalent in the eastern two-thirds of the United States.

The Snowberry Clearwing is typically found in open and semi-open habitats, including gardens, fields, and forest edges. It prefers areas where host plants such as honeysuckle (Lonicera spp.) and snowberry (Symphoricarpos spp.) are abundant. These environments usually feature a temperate climate with seasonal variations in temperature and precipitation.

Hemaris diffinis occupies the niche of a day-flying moth that mimics the appearance and behavior of a bumblebee. This mimicry helps it avoid predators. It is an important pollinator, feeding on nectar from a variety of flowering plants, including milkweed, lilac, and phlox. Its larvae feed on the leaves of host plants, primarily honeysuckle and snowberry, contributing to its role in the ecosystem as both a pollinator and a herbivore.
