There’s a small black dash (or “sleepy eye” mark) near the middle in the upper forewing, which gives it its unique name. Males are usually more uniformly orange, while females tend to be paler and somewhat streaked source.

You will find that the Sleepy Orange butterfly belongs to the Pieridae family, also known as the “Whites and Sulphurs.” It exhibits two seasonal color forms, with the ventral hindwing changing its appearance depending on the wet or dry season source. This intriguing butterfly offers a captivating glimpse into the world of butterflies and their diverse features.

Identification of Sleepy Orange

Color and Wingspan

The Sleepy Orange is an orange butterfly with black borders. Its wingspan ranges between 1.5 and 2 inches (38-56 mm). The underside of the wings may look tan, yellow, or brown, respectively, depending on the seasonal color forms. Here’s a brief description of its appearance:

  • Males have a uniform orange color on their upperside
  • Females are paler with some streaks

Life Cycle of Sleepy Orange

Eggs and Hatching

When it comes to the life cycle of the Sleepy Orange butterfly, the journey starts with the eggs. They are tiny, round, and pale greenish-yellow in color. As time passes, you may notice the eggs becoming darker, signaling their approaching hatching period.

During this phase, it’s essential to keep an eye out for any changes. The hatching process usually occurs within a few days, revealing a small and hungry caterpillar.

Larva to Chrysalis

Once the caterpillar has emerged from its egg, its main goal is to feed and grow. As it eats and develops, the caterpillar will go through several stages, known as instars. Throughout these periods, the larva will undergo noticeable changes.

Finally, the caterpillar is ready for the next transformation. It finds a secure spot, often on a stem or leaf, preparing to become a chrysalis. As it encapsulates itself, the outer skin hardens, turning into a brownish-black protective shell. Inside, the larva is busy morphing into a beautiful Sleepy Orange butterfly.

Keep in mind that the entire life cycle of the Sleepy Orange can be fascinating to observe, offering insight into the intricate workings of nature. Just remember to maintain a friendly and respectful distance, allowing these delicate creatures to thrive undisturbed.

Habitat and Distribution

Sleepy Orange in America

The Sleepy Orange butterfly can be found in various habitats across North America. You may come across these beautiful butterflies in open areas such as fields and woodlands. They also thrive in roadside environments and valleys.

Sleepy Orange butterflies also enjoy wetter areas. You might spot them near swamps, ponds, and waterways. Their distribution in the United States covers the eastern regions and reaches as far west as Southern California.

Global Distribution

Besides North America, Sleepy Oranges also have an extended distribution range. They can be found in the West Indies, Belize, and Costa Rica, making them quite a cosmopolitan species.

In summary, the Sleepy Orange butterfly can withstand various environments and habitats. They are present in both open and wet areas, as well as in the valleys and woodlands. Their distribution covers not only the United States but also extends to other regions such as the West Indies and Central America. Keep an eye out for these fascinating butterflies when exploring nature, whether it’s a field or a pond, and enjoy their vibrant presence.

Behavior and Adaptation

Seasonal Forms

The Sleepy Orange butterfly exhibits different forms depending on the season. In the summer, you’ll observe the summer form, characterized by bright orange wings with a black border. As the weather cools and fall approaches, these butterflies transition into their winter form, displaying duller, more muted orange tones on their wings. This adaptation helps them blend in with their surroundings during the changing seasons.

Migration Pattern

Sleepy Orange butterflies are known to migrate seasonally through various regions. In the winter months, they tend to move southward to escape colder temperatures and find suitable habitats. On the other hand, they migrate northward during the warmer months to take advantage of abundant resources and breeding grounds.

It’s important to note that migration patterns can vary depending on multiple factors, including weather conditions and regional climates. For example, in particularly mild winters, some Sleepy Orange butterflies might not migrate as far south as usual.

In conclusion, the Sleepy Orange butterfly’s behavior and adaptation showcase remarkable resilience and versatility as they adjust to seasonal changes throughout the year.

Relationship with Plants

Host Plants

The Sleepy Orange butterfly has a strong relationship with various plants, especially their host plants. Host plants are essential for the caterpillar stage of the butterfly, providing nourishment for their growth and development. Common host plants for Sleepy Orange caterpillars include Cassia species such as sicklepod and partridge pea. Here are some characteristics of these host plants:

  • Sicklepod:
    • Leaves: pinnately compound with leaflets
    • Flowers: yellow with five petals
  • Partridge Pea:
    • Leaves: bipinnately compound with tiny leaflets
    • Flowers: vibrant yellow with a red center

These plants can be easily grown in your garden to attract Sleepy Orange butterflies and support their life cycle.

Nectar Source Plants

In addition to host plants, Sleepy Orange butterflies rely on nectar source plants for sustenance during their adult stage. They feed on the nectar of various flowers, which provide them with the energy they need to thrive. Some examples of nectar source plants common to Sleepy Orange butterflies include:

  • Aster species
  • Goldenrod species
  • Lantana species

To create a more butterfly-friendly environment, consider planting a variety of nectar source plants to attract Sleepy Orange butterflies and other pollinators. This will not only benefit the butterflies but also promote the health of your garden through increased pollination. Remember, when planting flowers for butterflies, opt for native species that are well-suited to your local climate and soil conditions. Whether you have a spacious garden or a small balcony, adding these plants will make your outdoor space brighter and more welcoming for these beautiful butterflies.

Conservation Status and Threats

The Sleepy Orange is a butterfly species that is not currently facing major threats. However, it is essential to be aware of its conservation status and potential threats to protect the population.

The NatureServe conservation status of the Sleepy Orange is G5, which means it is secure on a global level. Despite its secure status, you should still remain vigilant about potential threats that can affect this butterfly species.

Some factors that could affect the Sleepy Orange population include:

Over the years, our website, has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Not Southern Dogface Butterfly, but Sleepy Orange


new species
I’m pretty sure this is a Southern Dogface butterfly, which I didn’t find on your site. I don’t see the "eye" in the photo, and the coloration underneath I haven’t seen in any other photos on the web; although the site refers to an Autumn-Winter form of the butterfly that has magenta coloring underneath. Maybe this is the Autumn-Winter form? This was taken in Memphis, TN. Thanks again for keeping up such a great site.

Hi Again Tim,
It is contributors like you with your marvelous imagery that makes our site so special. We agree that this could be a Southern Dogface Butterfly, Zerene cesonia. We have located a site that states: “underside hindwing of wet season “summer” form is yellow; that of dry season “winter” form is mottled with black and pink.” This is a species that seems to exhibit much individual variation, and that could explain the absence of the dog’s eye.

Ed. Note: Mike Quinn writes “Not Southern Dogface, Sleepy Orange… Compare.”

I’ve never tried to capture or identify the yellow butterflies that constantly seem to visit our yard, but today this seems so much more entertaining than sitting at the work table. 🙂 I don’t know if I have this one right, but I think it’s in the Pieridae family, perhaps a Mexican yellow, Eurema mexicana. I looked in Bug Guide and in Butterflies and Moths of North America. I’m so sorry it isn’t a better photo. The weather continues warm and partly cloudy here in central Texas.

Hi Ellen,
We like your attitude.  You properly identified the family, but we believe this is a winter form of the Sleepy Orange,
Lbaeis nicippe, based on this photo on BugGuideIt is described on BugGuide as being:  “A medium-sized Pierid with a rather slow flight, usually close to the ground. Upperside of wings flash a lovely burnt orange. Underside of wings have variable markings: in winter form, underside of hindwing is brick red, brown, or tan; in summer form it is orange-yellow. Diagonal brown markings on underside of hindwings are distinguishable in all variations.”

After two nights of hard freeze, a few butterflies have warmed up enough to fly in search of nectar today. Most are too elusive for me, but these seem to love the autumn sage so much that they ignore nosy amateur photographers. Is it another sleepy orange? Many thanks!

Hello, I think we may be seeing more of the Sleepy Orange Butterflies. I should keep trying to find the name of this wildflower and plant it as ground cover if it isn’t noxious. The butterflies love it, and it’s hardy enough to endure cold night temps in the twenties and still thrive and bloom in January as soon as the afternoons warm up. The butterflies and wildflowers are amazingly resilient!

Hi Ellen,
It is nice to get the additional photo to supplement the image you sent in December of a Sleepy Orange.  We will request assistance with the plant identification from our readership.

Letter 6 – Sleepy Orange Butterflies


Sleepy Orange butterfly
I have a question concerning the wing structure on a Sleepy Orange butterfly. I am sending you 3 photos for consideration. I took some photos of a Sleepy Orange several weeks ago and notice that a little piece was missing from the end of it’s hind wing. I didn’t think too much about it at the time because I thought the little bit of yellow showing through was the color of the fore wing. I don’t think this is the case at all. Not until I recently photographed another Sleepy Orange and looked closely at the picture did I begin to question whether or not the hind wing was a two-layer wing. The second picture shows, what looks like a separating of the hind wing in little layers like old paint flaking off, revealing the layer underneath. What do you think? Is this wing perhaps a two layer laminate wing (if that’s the right way to describe it). When I went back to look at the older folders more closely, I notice in the 3rd picture a little piece of wing sticking out from the side. That’s where the little piece was missing. It would be interesting to know about the hind wing being a dual layer. Wonder if you peeled away the top layer would it reveal a bright yellow wing underneath the outer layer? It would be interesting to know. I have never notice this separating of the wing before. It looks too that it separated right where the little brown markings are on the hind wing. Maybe this is not what you do. Maybe you just identify them. If you accept the challenge of finding out, will you let me know? I would greatly appreciate it. Curious,
Patrick Crone

Hi Patrick,
While your theory is fascinating, it is not the case. All Lepidopterans, butterflies and moths, have scales on their membraneous wings. The phenomenon you observed is a damaged wing with a missing and or partially detached portion, and the coloration of the upper surface showing when the wings are closed. By the way, we are thrilled to have your images of the Sleepy Orange, Abaeis nicippe.

(10/20/2007) Another question about Sleepy Orange
I have another question about the Sleepy Orange butterfly. I was determined to get a shot of the wings open on the Sleepy Orange, Abaeis nicippe. I am really confused and need your help. Sleepy Oranges are hard to catch with their wings spread out so you can see the inside color of the wings. I have been trying really hard to get a shot when it flies away. After many tries, I managed to get a small glimpse of one as seen in the first photo. Today I was taking pictures of a Sleepy Orange and stayed with it to see if I could get a better shot of the wings open as it flew away to the next flower. I got a better shot of the whole wings and noticed the black border was different on this one. What’s going on? Is there a difference between the male and female? Which is which? The outside of both are the same though. Please help me. Just when I think I am understanding what’s right, I get thrown another curve ball. I’d really appreciate your help. Confused,
Patrick Crone

Hi again Patrick,
Our reference book, Butterflies Through Binoculars: The West by Jeffrey Glassberg, indicates that there is seasonal variablity in the Sleepy Orange. Additionally, there is often much variation between individual specimens. You might try to contact your nearest natural history museum to see if you can view their Sleepy Orange specimens to get some idea of the individual variation. We are not sure if there is an easy way to distinguish the sexes from one another. BugGuide does have an image posted that is identified as a male and female, and there is a difference in their wing markings similar to the difference your photograph indicates.

I found this poor butterfly on the sidewalk of a shopping mall. I think it’s a Sleepy Orange. I don’t know what happened to it. Sad.

Female Sleepy Orange

Hi Ellen,
We agree that this is a Sleepy Orange,
Abaeis nicippe, a female since it lacks the band on the lower wings visible in the wing pattern of the male.  Compare this image of a mounted female Sleepy Orange on BugGuide to that of a male, also on BugGuide.  Because of the way the wings are dislocated, we suspect trauma was involved in the death of this lovely butterfly.  Based on the numerous images posted to BugGuide as well as the fine photographs of Sleepy Oranges you have submitted to us in the past, it is difficult to get a photo of the dorsal view in a living specimen.

  • Thank you for your help! I may have found it in my reference book “Wildflowers of the Texas Hill Country”. The plant may be a variety of Corn-Salad, Valerianella amarella. If so, it’s a native plant known to be edible, an early bloomer, cold hardy, and an annual. The “Wildflowers of Texas” book says about a different species, Woods Corn-Salad, “It is an excellent plant for the wildflower garden, the white, lacy bloom-clusters mixing well with the other spring flowers. It is very difficult to distinguish the various species of corn-salad found in Texas, with the fruit-shape being the most definitive characteristic. Thank you again!
