Feeding and Nutrition

Nectar and Flowers

Snowberry clearwings and hummingbird clearwings are both drawn to the nectar of flowers. They have a preference for certain types of flowers, like vines, bluebells, monarda, phlox, and verbena. These insects play an important role in pollination as they move from one flower to another in search of nectar.

As a pollinator, the snowberry clearwing visits various types of flowers to gather nectar for its nutrition. The hummingbird clearwing does the same, with a similar taste in flora. Here is a comparison table of their preferred flowers:

Snowberry Clearwing   Hummingbird Clearwing
Vines                 Vines                
Bluebells             Bluebells            
Monarda               Monarda              
Phlox                 Phlox                
Verbena               Verbena              

Both snowberry and hummingbird clearwings contribute to plant pollination when they feed on the nectar of these flowers. This, in turn, helps in the propagation and maintenance of the plant population. As a gardener, providing a friendly habitat for these pollinators would be mutually beneficial to these insects and your garden’s overall health.

Remember to choose flowers that attract snowberry clearwings and hummingbird clearwings and plant them in your garden. This will not only ensure good pollination but also create a pleasant environment where these fascinating creatures can thrive.

Breeding and Life Cycle

Eggs and Caterpillars

During the breeding season, both snowberry clearwing and hummingbird clearwing females lay their eggs on the host plants. They choose plants that their caterpillars will later feed on, such as honeysuckle, snowberry, and hawthorn. When the eggs hatch, the caterpillars begin to feed on the leaves of these plants.

The caterpillars of both species have distinct appearances. Snowberry clearwing caterpillars are usually green with black spots and a yellow stripe along their sides. Hummingbird clearwing caterpillars, on the other hand, are mostly green with a dark green stripe running down their backs.

Cocoon and Adult Stage

As the caterpillars grow, they eventually reach their final instar and begin to pupate. They spin a cocoon within the leaf litter and debris on the ground. It takes about two weeks for the pupa inside the cocoon to develop into an adult moth.

Once the adult moths emerge, they begin to search for food and mates. Both snowberry clearwing and hummingbird clearwing moths are diurnal, meaning they are active during the day. They hover around flowers, sipping nectar with their long proboscis, much like hummingbirds.

The main differences between the two moths can be observed in their appearance. Snowberry clearwing moths have a yellow and black banded abdomen, while hummingbird clearwing moths have a greenish-yellow or tan body. Both species have a wingspan ranging from 1½ to 2¼ inches.

In summary, the breeding and life cycle of snowberry clearwing and hummingbird clearwing moths involve similar steps of egg laying, caterpillar feeding, pupation, and adult emergence. The main differences between the two species are their caterpillar appearances and adult moth colorations.

Interactions with Other Species

Predators and Defences

Birds and other predators often hunt both the snowberry clearwing and the hummingbird clearwing moths. These moths, however, have developed fascinating defense mechanisms to protect themselves. One such mechanism is their ability to mimic other species, such as bumblebees, to deter predators. While feeding, you might notice their rapid wing beats, which help them evade potential threats.

  • Snowberry clearwing: Fuzzy golden yellow body with black and yellow bands on the abdomen 3.
  • Hummingbird clearwing: Furry greenish-yellow or tan body with reddish-brown bands across the abdomen 2.

Mimicry and Camouflage

Both the snowberry clearwing and the hummingbird clearwing moths use mimicry and camouflage as ways to elude predators. By mimicking the appearance of bumblebees, they discourage would-be predators from attacking them.

  • Mimicry: Both species have evolved body colors and patterns that resemble bumblebees 3 2.
  • Camouflage: When resting, these moths often blend in with their surroundings, making it difficult for predators to detect them 1.

Given their striking resemblances to other creatures, it’s no surprise that snowberry clearwings and hummingbird clearwings often go unnoticed or are mistaken for insects, like bumblebees. Be sure to observe their unique behaviors and adaptations in the wild whenever you encounter them.

Attracting Clearwings to Your Garden

Garden Plants

To attract the beautiful snowberry clearwing and hummingbird clearwing moths to your garden, consider planting some of their favorite nectar-rich plants. These can include:

  • Honeysuckle: This vine or shrub produces fragrant, tubular flowers that are sure to draw in clearwing moths.
  • Dogbane: A perennial plant with small, fragrant flowers adored by clearwings.
  • Hawthorn: These shrubs or trees offer clusters of small, white flowers that provide nectar for clearwing moths.

Other plants that you can add to your garden for these pollinators are cherries, plums, mertensia, viburnums, and hawthorns3. Planting a diverse variety of these plants will help create a welcoming environment for both snowberry and hummingbird clearwings to visit.

Protecting Clearwings in Your Garden

It’s equally important to ensure that your garden provides a safe and comfortable habitat for these moths. Here are some tips to protect clearwings in your garden:

  • Avoid using pesticides: Chemicals can be harmful to clearwing moths along with other pollinators. Opt for natural pest control methods instead.
  • Provide shelter: Make small piles of branches or allow for leaf litter to accumulate. These can be used by the clearwings for attaching chrysalis or cocoons2.
  • Offer water sources: Incorporate shallow bowls with water or a bird bath in your garden that can serve as a water source for clearwings and other pollinators.
  • Allow areas for larval feeding: Snowberry and hummingbird clearwing caterpillars consume foliage of particular host plants1. Including these plants in your garden provides a home not just for the adult moths, but for their larvae as well.

By following these tips and incorporating their preferred plants, you can create a vibrant garden that is a haven for both snowberry clearwing and hummingbird clearwing moths.

Letter 1 – Possibly Snowberry Clearwing Caterpillar


pink and green horned caterpillar
June 30, 2010
I took a picture of a large pink and green caterpillar with a single horn that I found in the Carbon County, PA area. It was in a grove of crabapple trees. It was discovered in mid June. Any help on identification would be greatly appreciated.

Possibly nowberry Clearwing Caterpillar

Hi Jessica,
Your caterpillar is a Hornworm in the family Sphingidae.  We are nearly certain your caterpillar is that of a Snowberry Clearwing,
Hemaris diffinis, and we are basing that on a photo posted to BugGuide.

Letter 2 – Pecan Bark Borer or Lesser Pecan Tree Borer


Clear Winged Moth – Synanthedon geliformis
May 5, 2010
I took this picture of a elm borer moth in mid-April and ID’d the moth easily enough; thankfully I noticed in the picture that the antennae are a little fuzzy and started with moths – I’d though it might be a wasp when I spotted it, with those narrow looking black wings. It took me a lot longer to ID the bush it was visiting, some sort of viburnum, I’m pretty sure now. It’s part of a neighbor’s hedge, but they didn’t know what it was. Since this is a still picture, it doesn’t show that the moth was flexing just the tip of it’s abdomen up occasionally.
I love your website. It has really helped learn more about ID’ing the smaller fauna of our world.

Pecan Bark Borer

Hi Karen,
First, we want you to know that we are setting your photo to post on Mother’s Day because we are leaving our office behind for a few days to visit our mother in Ohio and we will not be checking our email nor posting any letters while we are away.  Your letter has us quite puzzled because you mention using our humble site to make identifications, yet we do not have an example of a previous posting of Synanthedon geliformis, and furthermore, the single image posted to BugGuide does not list a common name.  We next tried a google search of the scientific name, and we found a mounted specimen posted to the Moth Photographers Group website, but again with no common name.  There appears to be a real dearth of information on this species online, but eventually we discovered a mention on the Index to the Common Names for Florida Lepidoptera website, where it is called a Pecan Bark Borer.  More searching led us to the Full Text of Pecan Insects online and this information:
(Synanthedon (Sesia) geliformis Walker.)
Two different species of clear winged moths, both related to
each other and to the peach tree borers, occur on pecan. One
species has been recorded by Ilerrick* as attacking the pecan in
Mississippi and this species appears to be the one attacking it in
North Carolina. The moth is deep steel blue in color with yellow
bands on abdomen and legs. Gossardt found a species attacking
pecan in Florida and, not finding the adult, judged it to be the
same insect. We have never taken this insect in Georgia, our form
producing a moth which is dark brown in color, with a bright red
hind body, or abdomen. It also seems probable that this is the
species occurring in Florida. Since this form is related more
closely to the Lesser Peach-tree Borer, and since moreover, the
name Pecan Tree-borer has already been applied to the other spe-
cies, it has seemed best to call our insect the Lesser Pecan-tree
