Building a Habitat for Monarchs
Kensleigh and Zola with their completed Critter Comfort Cottage.
Our design has two chambers because older instars can accidentally eat smaller instars, so we built it this way to help prevent this from happening. The first chamber holds eggs and first and second instars. Once they reach the third instar we will move them to the second chamber, where they can grow into the fourth and fifth instar then chrysalis, where they complete their metamorphosis into a butterfly. We made it big enough so that we can put the milkweed into the habitat. We have milkweed in the habitat to feed the caterpillars. The caterpillars eat a lot which means they also poop a lot. So we put in poop trays so that you can easily take it out, clean it and put it back in. Chamber 1 has a rain cover to help stop rain and flooding from coming into the habitat because the baby caterpillars could drown. Chamber 2 has a plastic lid for chrysalis making on the ceiling.
We worked together to build plastic cup towers to keep the net up and stop it from falling. We used duck tape to tape the cups together. Then we used Velcro to keep the net up on the cup towers. We used several recycled items in our creation including a plastic container lid used as a base, plastic deli trays used as the poop catchers, and a plastic deli lid used for chrysalis, and an amazon bubble mailer for the rain protector.
Research and Design Planning
Chamber 2 (on the left in the image above) will house older instars, stage 3, 4, and 5, including the chrysalis and adulthood butterfly stage.
Once they emerge as a butterfly they will be released.

Cottage Construction and Design Documentation
We worked together to build the Monarch habitat on November 23, 2021 following our drawn design plan. We used the materials listed below.
Habitat Features – Close-Ups
Recycled trays were used as poop catchers. The tray can be easily removed for cleaning.
Instars can form their chrysalis on the plastic lid on ceiling.
Foreground- Chrysalis already formed
Background- Instar beginning to form chrysalis
Instars eat milkweed plants. We built the habitat big enough to insert an entire potted plant!
Top Right- recycled Amazon bubble mailer prevents rain from collecting in the habitat and drowning young instars.
Critter Test – Caring For Instars
Project Log- Critter Test Observations
| Date | 1st Chamber Observations | 2nd Chamber Observations |
| November 23, 2021 | Instar ‘A’ – 3/4 cm in length, stage 1 Egg was observed on a leaf  | Instar ‘B’ – 4 cm in length, stage 5 |
| November 28, 2021 | Instar ‘A’ – 1 1/2 cm in length Instar ‘C’ – newborn 1/2 cm – egg had hatched! | Instar ‘B’ – bright green chrysalis formed on leaf |
| December 2, 2021 | Instar ‘A’ – 2 1/2 cm in length Instar ‘C’ – 1 cm in length (doubled in size!)  | Instar ‘B’ – leaf that chrysalis was on wilted so we taped it on the plastic lid. |
| December 4, 2021 | Instar ‘A’ – 3 cm in length –> moved to Chamber 2 Instar ‘C’ – 2 cm in length (doubled in size again!)  | Instar ‘B’ – still a chrysalis Instar ‘A’ had molted and was moved to Chamber 2.  |
| December 7, 2021 | Instar ‘C’ – 3 cm —> moved to Chamber 2 | ‘A’ – bright green chrysalis ‘B’ – dark green chrysalis  |
| December 9, 2021 | No more instars in chamber 1. | ‘A’ – darker green chrysalis ‘B’ – chrysalis clear and empty, butterfly emerged and was released Instar ‘C’ – made “J” shape, starting to make chrysalis    |
| December 10, 2021 | ‘A’ – dark green chrysalis ‘C’ – bright green chrysalis | |
| December 12, 2021 | ‘A’ – dark green chrysalis ‘C’ – bright green chrysalis | |
| December 15, 2021 | | ‘A’ – very dark black chrysalis in the morning, by the afternoon, the butterfly had emerged – (see video of release below) ‘C’ – darker green chrysalis |
| December 18, 2021 | ‘C’ – very dark black chrysalis in the morning, by the afternoon, the butterfly had emerged and was released This was the final butterfly release. It was extra special as ‘C’ had hatched from its egg and was born in our Critter Comfort Cottage! |
We are thrilled our habitat performed so well.

Design Details
These plants are fake. The butterflies and caterpillars are masterpieces made by the team using clay, plaster, and ceramic paint to present this project face to face.
This is totally amazing! What a concept. For idea to execution these two little ladies are truly exceptional!
Awesome shelter! I’m sure your caterpillars will love having so much room to grow and many yummy flowers to munch on!!
Very well done! You have solved a problem for the Monarchs, great job!
Bravo, ladies!!! Not only is your design aesthetically appealing but it protects the eggs from predators and keeps the baby instars safe as they grow! How brilliant to move the caterpillars into different chambers. I even appreciate that you have an effective way to collect the waste which can be troublesome in many designs and harmful, too. Great research and presentation❤️. So proud of all your hard work and effort!! 🦋
Wow! Your team did a WONDERFUL job. You all portrayed a lot of creativity and organization putting your project together and presenting it. I learned so much! Way to go!
I LOVE your work! It is so complete! Thank you for your research and your data. Thank you for this very original Critter Comfort Cottage for your butterfly friends. I enjoyed your presentation with your videos, pictures, tables, and explanations. Well done Chiquitinas!!!!
WOW! This is an awesome project. A lot of work and thought went into it. I learned a few things. Thanks for sharing.
