The hummingbird moth is a fascinating creature, often mistaken for its namesake – the hummingbird. They share similarities in their hovering movements and feeding habits, making them an intriguing subject to explore. As a member of the Lepidoptera order, hummingbird moths have wings covered in scales, but some species lose many scales, giving them the name clearwing hummingbird moths [1].

These moths have a “furry” body with color variations ranging from greenish-yellow to tan and reddish-brown [2]. Feeding on nectar from flowers, hummingbird moths have long proboscises for efficient extraction during the day [3]. Unlike butterflies, moth antennae are feathery or saw-edged, making it easier to distinguish between the two [4].

Overview of Hummingbird Moth

Types of Hummingbird Moths

Hummingbird moths belong to the Sphingidae family and are found across North America, Europe, Asia, and Africa. They are classified into several types, including:

  • White-lined Sphinx: A common species with a distinctive striped pattern.
  • Snowberry Clearwing: Resembles a bumblebee with yellow and black bands.
  • Hummingbird Clearwing: Has a greenish-yellow or tan body with a reddish-brown band.
  • Slender Clearwing: Similar to the Hummingbird Clearwing but with a slimmer body.

Comparison to Hummingbirds

Some similarities between hummingbird moths and hummingbirds are:

  • Both hover while feeding on nectar
  • Both have quick wing movements and the ability to fly backward
  • Both feed on similar flowers

However, there are differences, such as:

  • Hummingbird moths have antennae
  • Hummingbirds have feathers, while moths have scales on their wings
  • Hummingbirds are birds, while hummingbird moths are insects

Convergent Evolution

Convergent evolution is when unrelated organisms independently evolve similar traits due to similar environments or ecological niches. In the case of hummingbird moths and hummingbirds, convergent evolution explains their similar appearance and behavior:

  • Both have evolved to hover and feed on nectar from flowers
  • Their body structures allow them to access flowers that other pollinators can’t reach
  • Their fast wing movements enable them to maintain the energy needed for their feeding habits

Overall, hummingbird moths are fascinating insects that share many traits with hummingbirds due to convergent evolution. Their unique adaptations and striking appearance make them a delightful sight in gardens and natural habitats.

Physical Characteristics

Wings and Flight

  • Wings: Hummingbird moths possess clearwing wings, which are due to the loss of many scales from their wing patches.
  • Wingspan: These moths have a wingspan of 1½ to 2¼ inches.

Hummingbird moths have a unique flight pattern, hovering over flowers to feed on nectar during the day.

Body and Size

Antennae and Legs

  • Antennae: Unlike butterflies, hummingbird moths have feathery or saw-edged antennae.
  • Legs: These moths possess six black legs which help them grip flower stems while feeding.

Lifecycle and Behavior

Caterpillars and Host Plants

Hummingbird moth caterpillars, also known as hornworms, are large and robust. They are known for their distinct spine or “horn” at the hind end source. These caterpillars feed on the leaves of various host plants, some of which include:

  • Evening primrose
  • Night blooming jasmine
  • Bred valerian

Cocoon and Pupa

After extensive feeding, the caterpillar forms a cocoon, which helps in transforming into the pupa stage. The pupa is often well-camouflaged, making it difficult for predators to detect.

Mating and Eggs

Mating occurs shortly after the moths emerge from the pupa stage. After mating, the female lays eggs on the host plants, ensuring that the caterpillars have a readily available food source upon hatching.

Feeding Habits and Diet

Adult hummingbird moths have a long proboscis which allows them to hover over flowers and drink nectar as their primary food source source. Examples of flowers they visit include:

  • Monarda flowers

Daytime and Nocturnal Activity

Hummingbird moths are unique because they can be active during the day and at night. Most moths are nocturnal, but hummingbird moths have adapted to visit flowers during daytime as well.

Pollination and Hovering

Hummingbird moths serve as efficient pollinators, hovering over flowers while feeding, much like hummingbirds. This hovering behavior allows them to transfer pollen from one flower to another, playing a crucial role in plant reproduction.

Distribution and Habitats

North America

Hummingbird moths are found across North America, especially in meadows and gardens. In the US, they are commonly seen feeding on nectar from various flowers.

Examples of habitats:

  • Meadows
  • Gardens


In Europe, these fascinating moths can be spotted visiting flowers and hovering around plants in locations such as:

  • Forest clearings
  • Gardens


Hummingbird moths are also present in Asia, where they inhabit:

  • Woodlands
  • Flower-rich areas


Although not as widespread in Africa, some hummingbird moth species can be found in specific habitats such as:

  • Coastal areas
  • High altitude meadows
Continent Habitat Examples

Europe Forest clearings, Gardens
Asia Woodlands, Flower-rich areas
Africa Coastal areas, High altitude meadows

Flowers and Pollination

Attracting Hummingbird Moths

Hummingbird moths are attracted to bright and fragrant flowers, so adding these types of plants to your garden can help entice them to visit. For example, some popular flowers that may attract hummingbird moths include:

  • Honeysuckle
  • Phlox
  • Verbena
  • Butterfly bush
  • Bee balm (Monarda)
  • Salvia

These plants offer nectar and appealing scents that draw in pollinators like the hummingbird moth.

Nectar and Flower Preferences

Although hummingbird moths will feed on the nectar from various flowers, they do have some specific preferences. Their larvae need more specific food plants, such as several species of honeysuckle, dogbane, or some members of the rose family like hawthorn, cherries, and plums.

Here’s a quick comparison of some of the mentioned flowers and their characteristics:

Flower Color Scent Nectar Rich Larval Food
Honeysuckle Yellow/Red Yes Yes Yes
Phlox Pink/White Yes Yes No
Verbena Purple Yes Yes No
Butterfly Bush Purple Yes Yes No
Bee Balm Red Yes Yes No
Salvia Blue Yes Yes No

In addition to their preferred flowers, hummingbird moths will also visit other flowers with accessible nectar. Remember to provide a range of flower types to accommodate for their needs and attract these fascinating pollinators to your garden.

Common Predators and Survival Strategies


Hummingbird moths, also known as sphinx moths and hawk moths, encounter various predators in their environment. Some common predators include:

  • Birds
  • Bats
  • Spiders
  • Praying mantises


To evade these predators, hummingbird moths employ different survival strategies. Camouflage is one such strategy, where their unique coloring allows them to blend into their surroundings. For instance, their rich reddish-brown color helps them resemble tree bark or leaves when at rest1.


Mimicry is another way hummingbird moths protect themselves from predators. By resembling hummingbirds, they exhibit an example of convergent evolution, where unrelated species develop similar features due to similar ecological pressures. This similarity can confuse potential predators, increasing their chances of survival. Some features that make hummingbird moths resemble hummingbirds include:

  • Fuzzy appearance
  • Wing shape
  • Rapid wing movement
  • Hovering behavior

These survival strategies, such as camouflage and mimicry, help hummingbird moths outsmart their predators and continue with their essential role as pollinators in their ecosystems.

Rare Species and Conservation

Letter 5 – Xylophanes pluto: Imago and Caterpillar


Mystery Sphinx Moth Identified!!
Scrolling through your caterpillar pages, I recognized Xylophanes pluto as the larvae of the moth in the photo I sent you a few days ago. I’m raising another one now. Yesterday it molted and changed from bright green to deep brown in a matter of hours. Thanks for your fascinating web site!

We are happy you identified a caterpillar we did not have a chance to write back to you about.

Actually the insect I was trying to identify was the Xylophanes Pluto moth, not the caterpillar. I’m sending the photo again, since I don’t believe you have one in your database.
Keep up the wonderful work!

Hi again Sacha,
Thanks so much for sending us the photo of the adult Xylophanes pluto, but we are a bit confused as you mention a larva and we missed you original email. Do you have a caterpillar photo to add to this posting? Can you provide a location to add to the posting? Thanks. We are copying Bill Oehlke on this email as he is keeping comprehensive data on the species distribution of Sphinx Moths in North America.

Update: (07/20/2008)
Hi Daniel, Here is the text of my original letter, sent on 7/16/08: Maybe you can help me identify this sphinx moth which hatched from a caterpillar I found on my pentas here in Fort Lauderdale, FL. It is similar to the Virginia Creeper sphinx , but different enough that I think it’s something else. I checked through the “moths” sections and didn’t see an identical one. Any idea? Thanks, Sascha In the first letter, I neglected to mention that I’d hatched the moth – or rather, sheltered the larva so I could watch it pupate and hatch. A few days after sending that letter, I recognized the Xylophanes Pluto caterpillar on your website. I didn’t get a chance to photograph the first caterpillar before it changed, but here are some photos of the one I’m currently watching. Although this one is the brown morph, the adult moth featured in the photo was from the green morph. Bill Oehlke might like to know that there are also Tersa Sphinx caterpillars on the same penta bush. I am happy to provide information and photographs for his efforts and yours.

Hi again Sascha,
Thanks for the additional information, the wonderful new photos of the caterpillar, and for assisting Bill Oehlke.
