Do not mistake hummingbird moths (Hemaris) for hummingbirds. They fly and move just like hummingbirds, with a similar body shape and a rapid wing beat that produces a gentle humming sound.1
These insects are not only fascinating to watch but they are also pollinators that contribute to the health of our gardens and ecosystems.
If you’re eager to attract these creatures to your backyard, here’s how to transform your garden into a haven for hummingbird moths.
What are Hummingbird Moths?
Hummingbird moths are fascinating insects that are often mistaken for their namesake, the hummingbird. This is due to their unique ability to hover in mid-air while feeding on nectar from flowers, using their long proboscis (tongue).
They are also similar in size and shape to hummingbirds, with a plump body and rapid wing movements that create a humming sound.
Types of Hummingbird Moths
There are only four are considered “true” hummingbird moths:
- Snowberry Clearwing (Hemaris diffinis): This common species is recognized by its olive green thorax and burgundy abdomen with black bands. It is found throughout North America, with a higher concentration in the western regions. Its larvae primarily feed on snowberry, honeysuckle, dogbane, and hawthorn.
- Hummingbird Clearwing (Hemaris thysbe): Similar in appearance to the Snowberry Clearwing, this species has a golden olive thorax and burgundy abdomen. It is more prevalent in the eastern parts of North America. Its caterpillars also feed on honeysuckle, dogbane, hawthorn, as well as viburnum and cherry.
- Slender Clearwing (Hemaris gracilis): Less common than the previous two, this moth has a darker olive green thorax and abdomen with narrower black bands. It prefers the northern regions of North America. Its larvae feed on honeysuckle and dogbane.
- Rocky Mountain Clearwing (Hemaris thetis): This species is primarily found in the Rocky Mountain region. It closely resembles the Slender Clearwing but has distinct orange-brown scales on its wings. Its caterpillars feed on honeysuckle and snowberry.
Where & When to Find Hummingbird Moths
Where to Find Hummingbird Moths
Hummingbird moths can be found in various habitats across North America, including:
- Gardens: They are frequent visitors to flower gardens, especially those with nectar-rich blooms like bee balm, phlox, verbena, and butterfly bush.
- Meadows: Wildflower meadows provide a natural source of nectar for these moths.
- Woodlands: Some species prefer the edges of woodlands, where they can find host plants for their caterpillars.
- Parks: Urban parks with diverse plantings can also attract hummingbird moths.
When to Find Hummingbird Moths
The timing of hummingbird moth activity depends on the species and location:
- Spring: Some species emerge as early as spring, coinciding with the blooming of early wildflowers.
- Summer: This is the peak season for most hummingbird moths, with increased activity during warm, sunny days.
- Fall: As the weather cools, hummingbird moths become less active and prepare for winter.
In warmer regions, there may be multiple generations of hummingbird moths throughout the year. In colder climates, they typically have one generation per year, with adults emerging in late spring or early summer.
Specific Times of Day
Hummingbird moths are primarily diurnal, meaning they are most active during the day. However, some species can be seen feeding at dusk or even during the night.
Tips for Attracting Hummingbird Moths
To attract these creatures to your garden, consider the following tips:
Plant Nectar-Rich Flowers
Hummingbird moths are drawn to tubular, fragrant flowers with abundant nectar. Include a variety of colors and shapes to cater to different species. Some excellent choices include:
- Bee balm (Monarda)
- Phlox
- Verbena
- Butterfly bush (Buddleia)
- Petunias
- Honeysuckle (Lonicera)
- Zinnia
- Salvia
- Four o’clocks (Mirabilis jalapa)
Plant flowers that bloom at different times throughout the year, ensuring a consistent nectar source for the moths. This will encourage them to visit your garden regularly.
Plant Host Plants
Cater to the caterpillars by including host plants for different species of hummingbird moths. Some common choices include:
- Snowberry (Symphoricarpos)
- Honeysuckle (Lonicera)
- Viburnum
- Dogbane (Apocynum)
- Hawthorn (Crataegus)
- Cherry (Prunus)
Provide a Water Source
Hummingbird moths need water to drink and cool down. Create a shallow dish or birdbath with pebbles or rocks for them to perch on.
Avoid Pesticides
Pesticides can harm not only hummingbird moths but also other beneficial insects in your garden. Opt for natural pest control methods whenever possible.
Create a Moonlight Garden
Hummingbird moths are attracted to light-colored flowers that reflect moonlight. Consider planting white or pale-colored varieties in your garden.
It may take some time for hummingbird moths to discover your garden oasis. Continue to maintain a healthy and diverse environment, and they will eventually find their way to your yard.
