Butterfly Garden

Back in 1991, Doug Beardsley of Mackinac Island had the wonderful idea of adding butterflies to his greenhouse and allowing customers to enjoy two of nature's most beautiful creations, and so originated Michigan's first Butterfly House.  Eighteen years later, the Original Mackinac Island Butterfly House has come a long way - evolving from a dirt floor with potted plants and just a handful of North American butterflies to a beautifully landscaped tropical jungle with hundreds of butterflies from all over the world.

Harvesting Blue Morpho Caterpillars in Costa Rica
Currently, the Butterfly House gets butterflies from Asia, Africa, North America, and Central America.  We receive 400-500 chrysalids (butterfly pupae) every week from butterfly farms and brokers.  At these farms, the butterflies are carefully breeded and their eggs raised into hungry caterpillars.  The picky caterpillars are fed their appropriate host plants (Monarchs eat only milkweeds, Blue Morphos eat plants in the pea family, etc.) until they are ready to become a chrysalis.  The farm workers then set aside some of the chrysalids to become the next generation of breeders, while the rest are carefully packed in cotton or styrofoam trays and shipped express to butterfly houses around the world.  Depending on the time of year, farms can be raising anywhere from a handful to tens of species at a time.  At any given time, the Butterfly House has between 60 and 80 species flying around in the garden.

Hanging A Shipment From Malaysia
When our shipments arrive, they are taken into our containment room and all the chrysalids are carefully inspected by our curator.  They are then hung on foam-covered rods to continue developing and are placed in our emergence window, where customers might be able to see a butterfly emerge from its chrysalis if they are lucky enough to come at just the right moment.  When a butterfly emerges, its body is swollen with fluid and its wings are tiny and folded up.  The struggle of coming out of the chrysalis starts the flow of fluid from the body into the veins of the wings, filling them in much the same way a raft is inflated.  For at least a half hour after the wings have filled, they are still wet and floppy, and the butterfly continues to hang upside down on its empty chrysalis until its wings are dry.  The butterflies in our window emerge every day, and every day they are carefully transported from the emergence window to the garden once they are ready to fly.

In our garden, the butterflies act just as they would in the wild.  They fly from flower to flower drinking nectar, collect on our plates of overripe banana slices to drink the juices, stretch out on a leaf to bask in the sun, defend their territories from other butterflies, and mate.  Although butterflies do mate in our garden, the females will not lay their eggs unless they find the host plant their species needs as a cateripllar (ex: Monarchs won't lay their eggs if there is no milkweed to be found).  We are very careful to not plant any host plants in our garden, so our female butterflies never lay their eggs.  Raising caterpillars in the garden is prohibited by the USDA since almost all of our butterflies are foreign, and they must be carefully controlled and contained so that they don't pose a threat to the outside environment.

No butterfly garden would be complete without Monarchs. These famous butterflies are found all over North America, and they can be seen both inside our garden and outside on the island, especially in the middle of summer.

When you first enter the Butterfly House, you will be given a FREE chart with the butterflies we receive the most often so you can identify them in the garden.  Listed below are the species currently on our chart, along with a sampling of some of the other species you might see.
