Idlewild Butterfly Farm

Idlewild Butterfly Farm is a privately-owned business in Louisville, KY that operates as a butterfly farm, insectarium, educational destination, and retail store. We promote butterfly habitat cultivation, sustainable agricultural practices, and biological alternatives to chemical pest control.

With the expertise of our staff of entomologists, we breed and rear our own stock of regional native butterflies for exhibits at zoos, botanical gardens, and conservatories across the United States. Butterflies are also available to our local customers for education at home and in the classroom. 

Take flight with Kentucky's Native


Idlewild Butterfly Farm raises butterflies that are native to Kentucky in our insect rearing laboratory. It all starts in our Butterfly Flight House where adult butterflies mate and lay eggs on their host plant. While you can come to Idlewild to see butterflies and learn all about the process of raising them, the primary function of our flight house is for reproduction, not display. Once their amazing life cycle is complete, Idlewild’s butterflies become part of interactive butterfly exhibits across the United States.

Habitat Conservation & Restoration

Native Plants

We are committed to ensuring the future of our planet for butterflies, insects and all living species. We provide plants and resources for increasing sustainable native butterfly habitat and founded the Re-wilding Louisville initiative to provide butterfly gardens at no cost throughout Louisville. The plants we sell are grown with the use of beneficial insects, never touched by insecticides, which is critical for their safe inclusion in a butterfly garden. To control pests we use "Good Bugs, Not Drugs."


Good Bugs, Not Drugs

To promote pollinator friendly native habitat, we provide a variety of alternatives to pesticides. We are also experienced in pest identification and working with commercial growers and home gardeners to address their agricultural pest problems using biocontrol or “good bugs, not drugs.” Beneficial insects are seasonally available for purchase, as well as garlic-based Mosquito Barrier yard treatment.
