The 30,000-square-foot (2,800 m2) facility is situated on 11 acres (4.5 ha) of land,[1] and contains five main exhibit areas to teach visitors about butterflies and other invertebrates.

It joined the Scientific and Cultural Facilities District (SCFD) as a Tier II organization in 1996, and in 1997 launched their first outreach program, the Bugmobile, which serves 20,000 students annually as of 2010.

[4] In 2008, the Pavilion’s curatorial department manager, Mary Ann Hamilton, served as a consultant for the NASA experiment “Butterflies and Spiders in Space.” She provided information for the teachers’ guide and assisted with ground control experiments at the Pavilion and in several classrooms in Colorado.

[7] In May 2017, the group announced plans to move the main Westminster operation to the new Science and Technology Park being developed at Colorado 7 and Sheridan Pkwy.

Here visitors can see Colorado's native insects, prairie dogs, and rabbits, and maybe even a heron, hawk, or eagle perched in a tree.

[10] The outdoor Dee Lidvall Discovery Garden includes a butterfly garden planted with pincushion flower, cosmos, nicotiana and other colorful flowers to attract local butterflies, and a xeriscape garden sponsored by the Colorado Cactus and Succulent Society that includes dry land plants such as cactus, hardy ice plant, penstemon, yarrow, and lavender.
