A butterfly house, or lepidopterarium is a facility for the breeding and display of butterflies, usually for educational purposes. Butterfly World, the first butterfly house in the United States, opened in Coconut Creek, Florida, in 1988. Now, butterfly houses are owned and operated by museums, universities, zoos, non-profit corporations, and private individuals as part of their residence. You can build your own butterfly house which my friend, Cee, and her husband did earlier this spring.
First, a little history. It all started with building the wine bottle garden to have a place to plant flowers to attract butterflies. From there, she began poking around on Facebook groups dedicated to raising butterflies. In 2017, she began hatching monarchs and successfully raised 480 monarchs and one swallowtail. In 2018, her goal was butterfly house. After much searching on the internet, she and her husband decided to build their own. She also planted a huge bed of milkweed, a food source and host plant for the monarch butterfly. Now, her back yard looks like this:
A GARDEN FOR BUTTERFLIES
Cee’s backyard garden is a peaceful paradise of dappled shade, flowers, and monarchs flying around. My immediate impression was a feeling of well-being that I don’t get in my own garden despite how much time I work in it. Note to self: plant more flowers that butterflies like.
This 16 foot by 6 foot milkweed was planted in the spring of 2018 on the left side of the new butterfly house. Cee has now learned that planting milkweed in large blocks is not a good idea. Once predators, such as the tachnid fly, find it, caterpillars become victims. She has now scattered pots of milkweed around the backyard.
THE BUTTERFLY HOUSE
This is Cee’s new 8 foot x 8 foot butterfly house built by her husband over 2 months of weekends. Cee helped him install the screen panels and the roof is made of clear corrugated vinyl panels.
The butterfly house allows Cee to keep more habitats. Last year, she released one Black Swallowtail. This year, she added the Gulf Fritillary to her impressive list of butterfly releases. Next, she hopes to be able to attract the Zebra Heliconian to her garden.

This next photo shows Cee’s mesh butterfly habitats from Amazon; the small green ones are around $10. Cee has found that viewing is easier with the black habitat. Three habitats are for monarchs, one for swallowtail and one for gulf fritillary.
Diseases in butterflies are more prevalent in climates that are warm year-round where the milkweed isn’t knocked back by the cold or a freeze. An infected monarch can drop OE spores onto milkweed leaves that are then eaten by the larva when it hatches from the egg. OE or Ophryocystis Elektroscirrha is a parasite that infects butterflies in the monarch species. To avoid OE, a special ratio of bleach and water is used on both the eggs of the caterpillars and the milkweed fed to them. It also helps to cut back the milkweed and allow it to regenerate. This is what Cee does for her monarchs:
- Find eggs on leaves.
- After 24 hours, to ensure the shell has hardened, it is safe to bleach eggs that have not hatched using proper bleach/water ratio and timing.
- Put in small container or put leaves in floral picks until eggs hatch.
- Move to habitat with similarly sized caterpillars, keeping bleached and unbleached separated since caterpillars from bleached eggs are less likely to be diseased.
- Keep in mesh habitat until they pupate and form chrysalis.
- After chrysalis has hardened (about 1 day), move to chrysalis “nursery.”
