A walk through the butterfly conservatory introduces the visitor to a world of grace and beauty. The constant mist creates a hazy habitat to support the lush green plants that are both food and home to the inhabitants. If you stand still for a few minutes, a butterfly might land on you, but don't try to pick them up--the oils on your hands contaminate their senses, interfering with their ability to find food. One display describes the differences among butterflies, moths, and skippers, and color charts help with identification. (A butterfly guide is available for a nominal fee.)

In the insect room you'll discover that honeybees beat their wings some 200 times per second, and beetles comprise one-fifth of all living things on earth. Meet arthropods (the scientific name for insects) that are native to Colorado, and see exotic species from around the world. A fascinating "touch cart" allows you to get up close to a cockroach or tarantula, assuming that you really want to.

The facility is planning a major expansion: a 31,000-square-foot glass pyramid across the street from its current location. Slated for completion in 2004, this striking structure will house an improved version of the groundbreaking tropical conservatory and butterfly habitat.

Also on the premises are a large gift shop and snack bar. Outside, a 1/2-mile nature trail meanders amidst cacti and other desert-friendly plants. Allow 2 to 3 hours.
