The hummingbird clearwing moth is a fascinating creature known for its unique appearance and behavior. These moths closely resemble hummingbirds as they hover over flowers, sipping nectar with their long proboscis during the day. Although they are part of the sphinx moth family, their distinct features and daytime habits have earned them a special spot in the hearts of nature enthusiasts.
These moths can be found throughout various parts of the United States, with their range extending from the Pacific Northwest to the southeastern areas of the country. Their favorite flowers to feed on include honeysuckle, dogbane, and members of the rose family, like hawthorn and cherries source.
The adult hummingbird clearwing moth has a furry greenish-yellow or tan body, a reddish-brown band across the abdomen, and a wingspan of 1½ to 2¼ inches source. As they go through a complete metamorphosis, starting from a larva and transforming into a winged adult, these moths play a vital role in pollination, making them essential to our ecosystem.
Hummingbird Clearwing Moth Basics
Identification and Characteristics
The hummingbird clearwing moth is a fascinating insect that resembles a hummingbird in appearance and behavior. They belong to the Sphingidae family, also known as sphinx moths.
- Body: fuzzy olive to golden olive above, whitish below in the front part
- Wings: transparent with reddish-brown borders
- Wingspan: 1½ to 2¼ inches
Their unique features, such as a protruding head, large eyes, and a furry thorax, make them resemble bumblebees (source). They also have a conical abdomen and hover over flowers to feed on nectar, using a long proboscis.
Sphinx Moth Family
Hummingbird clearwing moths belong to the Sphingidae family, which consists of numerous species known for their rapid flight and agile hovering abilities. The hummingbird clearwing is a species in this family that mimics hummingbirds and bumblebees to blend in while visiting flowers.
Sphinx Moth Family Key Traits:
- Rapid flight and hovering abilities
- Large, prominent eyes
- Feeds on nectar from various flowers
While hummingbird clearwing moths are generally found during the day, most other sphinx moths are nocturnal. However, they all share a common need for specific food plants for their larvae, such as honeysuckle, dogbane, and members of the rose family (source).
Comparison Table
| Feature | Hummingbird Clearwing Moth | Other Sphinx Moths |
|---|---|---|
| Wingspan | 1½ to 2¼ inches | Varies by species |
| Coloration | Olive, golden olive, and reddish-brown | Varies by species |
| Active Time of Day | Daytime | Mostly Nighttime |
| Larval Food Plants | Honeysuckle, dogbane, rose family | Varies by species |

Behavior and Life Cycle
Feeding and Pollination
The Hummingbird Clearwing Moth feeds on nectar from various flowers, including honeysuckle, dogbane, and some members of the rose family, like hawthorn, cherries, and plums1. They exhibit pollinator behavior by hovering over flowers and using their long proboscis to feed on nectar2.
Reproduction and Development
- Female moths lay eggs on specific food plants.
- After hatching, caterpillars feed on these plants.
- Larvae develop into pupa and form a cocoon.
- The adult moth eventually emerges.

| Wings | Clear portions with some black scales6 | Opaque, usually black or brown |
| Legs | Black | Black or brown |
| Pollination | Yes | Yes |
| Feeding | Nectar from flowers | Nectar and pollen from flowers |
Habitat and Geographic Distribution
Hummingbird clearwing moths are mainly found in North America. They’re also observed in parts of Asia and Europe, but not in Africa. These fascinating moths are widespread across North America, from Newfoundland to Texas.
Their preferred habitats include:
- Meadows
- Fields
- Open woods
- Gardens
These moths are common in areas with diverse flora, as they feed on nectar from various flowers1. Their larvae specifically need food plants like honeysuckle, dogbane, and some members of the rose family, such as hawthorn, cherries, and plums2.
In summary, the hummingbird clearwing moth can be found in various habitats across North America and some parts of Asia and Europe. They prefer meadows, fields, and other open areas with diverse flora to support their nectar and larval food needs.
Attracting and Supporting Clearwing Moths
Garden Plants and Flowers
To attract hummingbird clearwing moths to your garden, consider planting flowers rich in nectar that they can feed on. Some examples of flowers preferred by clearwing moths include:
- Phlox: These flowers come in various colors and can easily attract clearwing moths to your garden.
- Verbena: This plant has beautiful blooms that offer plenty of nectar to support clearwing moths.
It is noteworthy that clearwing moths are also attracted to other flowering plants such as honeysuckle and dogbane.
Host Plants
Besides providing nectar-rich flowers, it is essential to offer host plants for the larvae of hummingbird clearwing moths. Some common host plants include:
- Hawthorns
- Cherry and plum trees
- Viburnums
These plants belong to the rose family and have leaflets that cater to the dietary needs of the clearwing moth larvae. Offering a variety of host plants in your garden can help support the entire lifecycle of these fascinating creatures.
Different Species of Clearwing Moths
Hummingbird clearwing moths are fascinating creatures that belong to the sphinx moth family, scientifically known as Sphingidae. These moths are often mistaken for hummingbirds due to their similar size and hovering behavior while feeding on nectar.
There are several species of clearwing moths that exhibit unique traits and appearances. Some notable species include the Snowberry Clearwing, Hemaris diffinis, and the White-lined Sphinx.
The Snowberry Clearwing (Hemaris diffinis) is distinguished by its bumblebee-like appearance. Some features of this species are:
- Olive to golden olive color on the upper body
- Dark burgundy or blackish abdomen
- Whitish legs and front part of the body
In contrast, the Hemaris diffinis or the Hummingbird Sphinx, also known as the Common Clearwing, exhibits a slightly different appearance:
- Reddish-brown coloration on parts of the body
- Clear portions on their wings, earning them the “clearwing” name
Lastly, the White-lined Sphinx is another hawk moth species with distinct characteristics:
- Large size and striking patterns on its wings
- White lines across the wings and pink bands across the abdomen
Here’s a comparison table of the three species mentioned:
| Species | Colors | Wing Pattern | Similar To |
|---|---|---|---|
| Snowberry Clearwing | Olive to golden, dark burgundy | Clear portions | Bumblebee |
| Hemaris diffinis | Reddish-brown | Clear portions | Hummingbird |
| White-lined Sphinx | White lines, pink bands | Bold patterns | Hawk moths |
These clearwing moth species play an essential role as pollinators, benefiting various plants and ecosystems. It’s crucial to protect and preserve these delicate Lepidoptera, as they are an integral part of maintaining a healthy environment.
