Lifecycle of Bordered Patches

The lifecycle of the Bordered Patch butterfly, like other butterflies, consists of four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult.

Each stage has its unique characteristics and functions, contributing to the butterfly’s fascinating journey from egg to winged beauty.


After mating, female Bordered Patches lay their eggs on the undersides of host plants, primarily those in the sunflower family.

The eggs are tiny, round, and pale green, blending seamlessly with the plant leaves.

Within a week or so, the eggs hatch, giving birth to the next stage: the caterpillar.

Larva (Caterpillar)

The Bordered Patch caterpillar is known for its striking appearance, often showcasing bright colors with contrasting patterns, which serve as a warning to potential predators of their unpalatable nature.

As they grow, caterpillars molt several times, shedding their old skin to accommodate their increasing size.

The caterpillar’s primary function is to eat and grow. They feed voraciously on the leaves of their host plants, storing energy for their upcoming transformation.

After reaching a certain size and maturity, the caterpillar seeks a sheltered spot to begin its transition into the pupal stage.

Pupa (Chrysalis)

The caterpillar forms a chrysalis, a protective casing, where it undergoes a remarkable transformation, a process known as metamorphosis.

Inside the chrysalis, the caterpillar’s old body parts undergo a dramatic transformation to become the various parts of the adult butterfly.

This stage can last anywhere from a few days to several weeks, depending on environmental conditions.


Once the transformation is complete, the adult butterfly emerges from the chrysalis, revealing its vibrant wings and patterns.

After allowing some time for its wings to dry and harden, the Bordered Patch takes its first flight.

Adult Bordered Patches primarily feed on nectar from flowers, playing a crucial role as pollinators.

The primary goal of the adult stage is reproduction. Males and females mate, and the cycle begins anew with females laying eggs.

Throughout their lifecycle, Bordered Patches face various challenges, from avoiding predators to finding suitable host plants for laying eggs.

Their vibrant colors, not just in the adult stage but also as caterpillars, serve as both a warning to predators and a spectacle for human admirers.

Migration and Seasonal Behavior

The Bordered Patch butterfly, like many butterfly species, exhibits specific behaviors in response to seasonal changes. These behaviors are crucial for their survival, ensuring they can find food, reproduce, and avoid adverse conditions. Here’s a detailed look at their migration and seasonal behaviors:

Migration Patterns

  • Why They Migrate: Bordered Patches, primarily found in North and Central America, migrate to ensure they have access to their preferred host plants and to escape unfavorable weather conditions, especially during colder months.
  • Routes: While they don’t undertake long-distance migrations like some other butterfly species (e.g., Monarchs), Bordered Patches do move to warmer regions or lower altitudes during colder months. In the U.S., this might mean a southward movement or seeking sheltered areas.
  • Navigation: While the exact mechanisms remain a subject of study, it’s believed that Bordered Patches, like other butterflies, use a combination of the sun’s position, the Earth’s magnetic field, and landscape features to navigate.

Seasonal Behavior

  • Spring: As temperatures rise, Bordered Patches emerge from their overwintering sites. This is a time of increased activity, with adults seeking nectar-rich flowers and suitable sites to lay their eggs. The abundance of food and warmer temperatures make spring a prime breeding season.
  • Summer: The warm months of summer see the highest activity levels. Multiple generations of Bordered Patches can be born during this period. Adults continue their quest for nectar, and caterpillars voraciously feed on host plants.
  • Fall: As the days shorten and temperatures drop, Bordered Patches prepare for the colder months. Adults might start their minor migratory movements, seeking warmer or more sheltered areas. Some might lay eggs that will overwinter and hatch the following spring, while others might overwinter as chrysalises.
  • Winter: In colder regions, Bordered Patches enter a state of diapause, a form of hibernation. This state allows them to conserve energy and survive the cold months. In warmer climates or during mild winters, some adults might still be seen fluttering around on warmer days, but activity is significantly reduced.

Factors Influencing Migration and Seasonal Behavior:

  • Temperature: Bordered Patches are ectothermic, meaning their body temperature is regulated by the external environment. As such, they prefer warmer temperatures for activity and will seek out warmer regions or go into diapause during colder months.
  • Food Availability: The availability of nectar-rich flowers and host plants for their caterpillars plays a significant role in determining their movement and activity.
  • Photoperiod: The length of day and night can influence behaviors like mating, egg-laying, and migration. Shortening days in the fall can signal the approach of winter, triggering preparatory behaviors.

The Bordered Patch, Chlosyne lacinia, is a captivating butterfly native to North and Central America, celebrated for its vibrant wing patterns.

Thriving in open, sunlit areas, these butterflies are drawn to wildflowers like sunflowers and milkweed, making them a gardener’s delight.

Their unique appearance, characterized by colorful patches surrounded by darker borders, sets them apart, making them a favorite among butterfly enthusiasts.

Their lifecycle, from caterpillar to butterfly, and their relationship with specific plants, highlights the intricate balance of nature.

Reader Emails

Over the years, our website, has received hundreds of letters and some interesting images asking us about bordered patches.

Scroll down to have a look at some of them.

Letter 1 – Bordered Patch

Would like information regarding how to identify this butterfly
Greetings, Bugman!
I know you are extremely busy with the fast approaching school year (maybe it’s started already in your area, like here in Texas). I have searched several butterfly web sites and am unable to find a match for this butterfly. I live in Collin County, Texas, about 30 miles north of Dallas, and I first saw this butterfly in late August.

It likes my zexmenia bushes — althought it is not feeding on the flowers, but lighting on the leaves themselves. I was wondering if it could be laying eggs. Small to medium sized black caterpillars with an orange stripe down their back are having a feast on about a dozen of my zexmenia bushes right now and have been busy for about a week.

They look a little smaller than the Gulf Fritillary caterpillars on my passion vines. This is the first year I’ve had this caterpillar, and the first time I’ve seen these butterflies. They are fast moving and larger than Pearl Crescents but a little smaller than the Painted Ladies. If you do not have time to identify this butterfly, could you offer some other web sites that might do this?

I love your web site, and this is the first time I’m “Asking the Bugman”. I’ve had my butterfly garden for 10 years now, and it amazes me that there’s always something new happening in it. I’m surprised I can’t find this one in my butterfly guides, and I’m thinking maybe with this goofy weather it may be out of it’s normal range. Thanks for your assistance!

Hi Jackie,
These are very nice photos of the Bordered Patch, Chlosyne lacinia, a highly variable species. We got our first submitted photo of a Bordered Patch last week, also from Texas. The caterpillars you describe sound like the images posted for this species on BugGuide.

Can you identify this butterfly for me
Can you possibly identify this butterfly for me? I took this picture in Fort Worth, Texas at the botanical gardens. It was taken on August 26, 2007. I would like to know what it is. Thank you,

Hi Kristina,
Your butterfly is a very highly variable species known as the Bordered Patch, Chlosyne lacinia.

Hi Ellen,
The last time we posted a photo of a Bordered Patch,
Chlosyne lacinia, was in 2007, so it is wonderful to have your recent sighting documented on our site.  Thank you so much for sending both an open and closed wing view. 

BugGuide indicates the common name Naranjita, meaning “Little Orange” in Spanish, and we suppose this is due it it being a common species in Mexico.

Dear Bob,
We initially thought that because of the pronounced labial palps, that this might be a Snout Butterfly in the subfamily Libytheinae, but we could find no similar looking members of the subfamily from Brazil in our initial search.  While we cannot confirm the subfamily at this time, we are confident that the Brushfooted Butterfly family Nymphalidae is correct. 

We could not locate a match on Insetologia, our sister site from Brazil, nor did we have any luck on the Butterflies of Amazon & Andes.  Finally, we believe we found a match in the Bordered Patch, Chlosyne lacinia, which according to the Butterflies in Brazil and Argentina at Iguazu Falls during Focus On Nature Tours site, is called the Naranjita and “has a very variable pattern. It prefers sunny places and feeds on nectar”. 

The site also states:  “the Bordered Patch, the subspecies Chlosyne lacinia saundersi  This subspecies, in southeast Brazil and the Iguazu area, has more orange in the upperwings than other subspecies, hence the common name there of ‘Naranjita’. “  Now that we had a name, we did locate the Bordered Patch on the Butterflies of Amazon & Andes where it states: 

“Males are usually seen either when nectaring at Asteraceae, or when imbibing mineralised moisture from patches of damp ground. Females when freshly emerged are so heavily laden with eggs that they are barely capable of flying.”  We have examples of the Bordered Patch from North America in our archives.
