The Parnassian Butterfly is a fascinating species that thrives in alpine environments. These butterflies are not only visually captivating, but they also play important roles as pollinators and indicators of climate change. The distribution of Parnassian butterflies can help scientists understand how environmental conditions are shifting due to climate change.
Belonging to the family Papilionidae, Parnassian butterflies are characterized by their delicate, transparent wings and bold patterns. They can often be found in mountainous regions throughout North America, such as in the North Coast and Cascades. Though mesmerizing to observe, the biogeography of Parnassian butterflies dive deeper, revealing vital information about the impacts of the Pleistocene alpine glacier growth on alpine ecosystems.
Parnassian Butterfly Overview
Origin and Distribution
The Parnassian butterfly, scientifically known as Parnassius, is a genus representing a unique group of butterflies. They are predominantly found across Asia, Europe, and North America, including British Columbia, Washington, the United States, and Canada.
These butterflies belong to the family Papilionidae and are commonly found in alpine areas. They are known to have adapted to the montane landscapes, resulting from glacial growth during the Quaternary climate.
Parnassian butterflies come in various shapes and sizes, sporting different color patterns on their wings. Key features of Parnassian butterflies include:
- Distinctive wing patterns with a combination of white, black, and red colors
- Presence of a red ocellus, or eye-like marking, on the hind wings
- Generally larger wingspan compared to other butterflies
|White, black, and red
|Asia, Europe, North America
|Alpine, montane regions
|Various, including grasslands
Habitats and Altitudes
Meadows and Host Plants
Parnassian butterflies reside primarily in meadows. They lay their eggs on their host plants, mainly belonging to the Papaveraceae and Fumariaceae families1. Examples of host plants include:
- Bleeding heart
These host plants provide nourishment for the Parnassian larvae in their early stages of life.
Parnassian butterflies exhibit altitude preferences, typically inhabiting alpine regions2. Some key features of their preferred habitat include:
- High altitude meadows
- Cooler temperatures
- Alpine flora
|Other Alpine & Meadow Species
|Low to Medium
|Various Meadow Species
By staying in these preferred altitudes, Parnassian butterflies can thrive in their unique habitat among other alpine species.
Life Cycle and Reproduction
Stages of Life Cycle
The Parnassian butterfly’s life cycle consists of four main stages:
- Egg: Tiny, cream-colored eggs laid by the female on the underside of host plants.
- Larva: Known as caterpillars, these worm-like creatures hatch from the eggs and feed on the host plant.
- Pupa: The transformation stage, where the caterpillar forms a protective chrysalis to turn into a butterfly.
- Adult: The final stage, when the beautiful and graceful Parnassian butterfly emerges from its chrysalis.
Mating and Mating Plugs
Mating: Male and female Parnassian butterflies perform a courtship dance before mating. Mating occurs when the male successfully positions himself to transfer sperm to the female.
Mating Plugs: Some male Parnassian butterflies produce a mating plug during copulation. This plug effectively blocks the female’s reproductive tract, preventing her from mating with other males and ensuring that the first male’s sperm is used to fertilize her eggs. This strategy helps increase the male’s reproductive success.
Here are some key characteristics of Parnassian butterflies’ life cycle and reproduction:
- Both males and females participate in the mating process
- Mating plugs can increase a male’s chances of fathering offspring
- The life cycle consists of four distinct stages
Here’s a comparison table showcasing the stages of the Parnassian butterfly’s life cycle:
|Tiny, cream-colored, laid on host plant leaves
|Caterpillars that feed on host plants
|Transformation in a protective chrysalis
|Graceful butterflies capable of mating and reproducing
Parnassian Butterfly Ecology
Diet: Nectar and Flowers
Parnassian butterflies, like most butterfly species, primarily consume nectar from flowers. They use their long, straw-like proboscis to sip nectar, providing them with energy and essential nutrients. Flowers that attract Parnassian butterflies and other pollinators include:
- Black-eyed Susan
- Joe-Pye weed
Pollinators and Interactions with Other Insects
Parnassian butterflies play a crucial role as pollinators, helping plants to reproduce by transferring pollen between flowers. While they are not as efficient pollinators as honey bees or bumble bees, their contribution to the ecosystem is significant.
Interactions with other insects
Parnassian butterflies share their habitats with other insects, including dragonflies, margined calligraphers, and miller moths. These diverse species often interact as they visit flowers for nectar or seek mates, providing a complex web of connections within the ecosystem.
Comparison of Insect Pollinators
|Near flower-rich environments
|Gardens, meadows, woodlands
|Mosquitoes, small insects
|Near water sources
|Plant sap, some nectar
In conclusion, Parnassian butterflies play an essential role in their ecosystem as both pollinators and members of a diverse insect community. Their consumption of nectar from flowers provides sustenance for themselves while supporting plant reproduction and ultimately contributing to the overall health and biodiversity of their habitats.
Parnassian Butterfly Conservation
IUCN and ESA Listing Designations
The Parnassian Butterfly is not currently listed under the IUCN or the Environmental Leadership Program. However, the conservation of these butterflies remains important due to their potentially significant role in cultural conservation and pollination.

Unique Facts and Stories
Yellow, Red, and Orange Spots
The Parnassian butterfly has distinct yellow, red, or orange spots on its hindwings, making it easily recognizable. These colorful spots serve various purposes, such as:
- Attracting mates
- Camouflaging against predators
- Mimicking other species for protection
Apollo Butterfly Comparisons
The Parnassian butterfly is often compared to the Apollo butterfly due to several similarities, including:
- White wings with black markings
- A wingspan of 1-2 inches
- Females being larger than males
However, there are also notable differences between the two:
|Yellow, red, or orange
|Red or orange
|Europe and Asia
|Varies by species
|Endangered in some areas
Interesting Research and Media Appearances
Parnassian butterflies have been featured in various research and media events, for example:
- Math at the Zoo: Shiran Hershovich, a mathematician, researched the flight patterns of Parnassian butterflies to develop mathematical models.

The Parnassian butterfly is not only fascinating in terms of its appearance but also in the role it plays in various ecosystems. Through research, conservation efforts, and media coverage, society can further appreciate these beautiful creatures and their impact on our world.
Over the years, our website, whatsthatbug.com 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 – Apollo or Parnassian Caterpillar or Cucullia species???
Here are some pics of the earlier instar. I apologize that they are a little out of focus. I was having trouble with my camera at the time & had to send it in for repairs soon after. I will also send a few more in separate emails as we have had some problems with our server lately, if you send more than two at a time they disappear into cyberspace. … The Parnassian was found in Well County North Dakota. I cannot remember what year though. I am thinking it was around 2003-2004? I can look for my records if you need to know. It was also found in town & feeding on Dill & Parsley. This set pictures are of the instar just before the last.
Hi again Misty,
First, we really want to thank you for identifying an earlier Parnassian Caterpillar that we had misidentified on our site back in 2006. We are also thrilled to get your photos of both the earlier striped caterpillar instar and the final spotted instar. In an attempt to not add any more confusion, here is what we do know. Parnassian is the common name for all butterflies in the genus Parnassius. In Europe, this same genus is known as the Apollo Butterflies. The genus Parnassius is found in mountainous areas of the northern hemisphere where there are snowy winters. There are several North American species. Neither Parnassius clodius, nor Parnassius phoebus are listed as living in North Dakota in our Butterflies Through Binoculars (the West) book and P. clodius has the more western range. There is much variability in the adult coloration, which complicates identifications. BugGuide lists another species, Parnassius smintheus, the Rocky Mountain Parnassius that ranges “From New Mexico north along the Rocky Mountains and into southwest Alaska.” All that said, we are eager to get your update from the expert on the proper species identification of your specimen. Thank you so much for adding to the information on our site.
Update: Differing Opinion
Thu, Dec 18, 2008 at 8:57 PM
The original ID of Cucullia intermedia (2006/01/20/probably-parnassus-butterfly-caterpillar-not- hooded-owlet-moth-caterpillar/ ) is probably correct, although moth caterpillars are not my area of expertise. In any case, these are not Parnassius larvae, which have fine black hairs (making them look somewhat velvety), all instars similar in appearance (black with rows of light spots), and feed on Sedum or Dicentra (not dill or parsley) locally. Please see this Parnassius smintheus from Idaho: http://outdoors.webshots.com/photo/1050616448038400999jjFBOj . North American Parnassian cats are rarely encountered, so a number of Internet photos are regrettably misidentified (such as http://www.butterfliesandmoths.org/species?l=1346 ).
I hope the above information is helpful.
Letter 2 – Colorful Transparent: Parnassus Butterfly from Israel
Butterfly in Israel
Location: Zippori stream, Israel
January 4, 2012 10:02 am
Hello Bug people!
I was on a hike in Northern Israel last weekend (a great way to see off the old year and start the new), and during the hike I saw a couple of these butterflies playing around. I was lucky enought to shoot one of them just before it flew off.
Quick research tells me it is an Archon apollinus bellargus, of the papilionoidae family. A loose translation of its Hebrew name is the ’Colorful Transparent’.
We are positively thrilled to receive your image of the Colorful Transparent. We were struck by its resemblance to members of the genus Parnassus, sometimes called Apollo Butterflies, which sad to say are highly sought by collectors and becoming endangered in their high altitude habitats in the Palaearctic. We suspect that they are taxonomically quite close to this lovely member of the same family. We found support for your identification on TrekNature which states: “One of the most primitive species of Papilionidae in Israel. It is the only specie in Israel which is active in the winter. its upper wings are bit transparent.” It is also pictured on the Tree of Life website which states: “Larvae of A. apollinus feed on species of Aristolochia (Aristolochiaceae).”
Letter 3 – Parnassian
one rare one…
Hi – Here’s maybe a new addition – seen in Southern Oregon – 5,000 ft. elevation… quite hard to find – parnassius phoebeus sternitzkyi – female.
We are thrilled to have received your photo of a Parnassian. We have gotten photos of the caterpillars, but this is the first adult. According to Jeffrey Glassberg, author of Butterflies Through Binoculars The West: “This distinctive group of swallowtails is restricted to northern climes. … After mating, males place a waxy cap, called a sphragis, over the females’ abdomen to prevent other males from mating. In Europe, this group is called Apollos. Most of the approximately 35 species are Eurasian, and since almost every mountain range has populations that look slightly different from the next mountain range, European and Japanese collectors have gone berserk in their pursuit of each variety, reportedly threatening the existence of some of them.” We also plan to post the photo of the Baltimore you sent in a different email.
Cool – there are common parnassians, then there are the rare ones. Sternitzkyi is among the rare and hard to find ones, not to mention one of the largest and ornately colored. Collectors and observers are very tight-lipped about where they find this bug – I found it in a remote colony that I would not share with anyone due to possible overzealous collectors… Your site is so cool – and so much fun!! Glad you could use a pic or two. I may have a few more rarities to email you…
Letter 4 – Parnassian Butterflies
Sat, Oct 18, 2008 at 7:25 PM
attached are male phoebus parnassian photo’s taken this past july. the one with the little dark hook like lines on the rear wing i believe is a high elevation parnassian.
the other two photo’s are also a male parnassian but according to glassberg they are low elevation. however i took the photo’s at roughly the same elevation (9,000 feet)but on different days.
Hi Again Venice,
We are always reluctant to post location photos for Parnassian Butterflies since they are endangered and since collectors are quite rabid about catching them. The Phoebus Parnassian, Parnassius phoebus, is highly variable, and isolated populations are often quite different from other populations. We would hate to have your mountain decended upon by Japanese and German butterfly collectors, but we are thrilled to post your gorgeous photos.
Letter 5 – Rocky Mountain Parnassian
Is Attachment 1 a sooty azure? So appreciate your help.
This is a Parnassian, but we are not certain what species. The Parnassians are found in both the mountainous areas of Western North America and Eurasia where they are called Apollos. The local populations of various species have much variablity and the same species might look quite different on neighboring mountains. With that said, you gave us no information. Your email is quite confusing. Did you also send a photo you believe to be a Sooty Azure? You did have Parnassian correct on the subject line. Where was the photo taken? Since collectors are rabid for the Parnassians, you don’t need to give us an exact location, but a general vicinity would be nice.
Follow-up on parnassian. The photo was taken in 1977 between Denver and Colorado Springs in the woods along County Line Road — a long time ago. From the web site “Moths & Butterflies” by Montana State Univ, I thought it might be a Sooty Azure. Thank you for verifying it as a Phoebus parnassian. I’m so grateful to my 4-year-old neighbor for referring me to your site, and thanks so much.
Regarding: Parnassian (01/13/2008) phoebus parnassian?
More follow-up on the Colorado Parnassian. The pictured butterfly likely is a Phoebus Parnassian, at least it would have been when the photo was taken. The parnassians, like many other butterfly groups, have been subject to taxonomic revisions in recent years. Depending on where you are or what books you read, the “phoebus” of Colorado are now considered a subspecies (Parnassius phoebus smintheus) or a distinct species (P. smintheus). Either way it is now generally called the Rocky Mountain Parnassian or, in parts of Canada, the Smintheus Parnassian.
Letter 6 – Rocky Mountain Parnassian
Subject: Transparent-winged butterfly
Location: Mt. Bross 12,000ft elev.
September 7, 2014 12:27 pm
I shot this butterfly on Sept 6, 2014 on Mt. Bross in Park County, colorado at an elevation of about 12,000 ft. I think it’s a Rocky Mtn. Parnassus or maybe a Checkered White. Its wings were mostly clear and it appeared to have no trouble flying around for half an hour before i finally got a few shots if it resting. I’ve never seen a clear-winged butterfly before, do you think it’s a mutation or is it possible that the color somehow got washed off in all the rain we’ve been having this summer.
We agree that this is a Rocky Mountain Parnassian, Parnassius phoebus, a species which Jeffrey Glassberg, in his book Butterflies Through Binoculars The West, calls the Phoebus Parnassian, though he acknowledges it has several subspecies including Parnassius phoebus smintheus. According to BugGuide, the Rocky Mountain Parnassian is Parnassius smintheus, and BugGuide provides the following information: “Antenna has alternate black and white rings. Upperside of forewing of females and most males with 2 red or yellow spots beyond the cell. In some males these spots are black.(1) Often called by the name Parnassius phoebus, a closely related Eurasian species. Many people consider all North American populations to belong to that species, many prefer to separate them. Some authors split North American populations into more than one species; usually two or three, with the northernmost populations included in P. phoebus, and the rest in P. smintheus; or, the Sierra Nevada populations may be separated as Parnassius behrii. These regional ‘species’ are best distinguished by where they are found.” Isolated populations often exhibit localized variations, so individuals on one mountain may look different from individuals on the next mountain. Regarding the transparency, we believe this is a result of the loss of scales that might be a natural occurrence in the species as BugGuide includes many images of more transparent individuals.
