Posted by: Kirsten Pisto, Communications The summer air is almost still, delicately scented with a sweet, seasonal bloom. Brilliantly winged creatures flit and float between lupine, spirea and honeysuckle. Here in the Molbak’s Butterfly Garden , speak softly and step carefully as you enter another world. Opening Sat., July 2, the new exhibit takes flight with 500 free-flying butterflies from at least 15 native North American species. You’ll get a full sensory introduction to the fragility and resilience of nature as flowers bloom and butterflies emerge around you. Photo: Dennis Dow/Woodland Park Zoo.

Their littleness can be measured in grams, their adult lifespan sometimes just months, weeks or days. Yet butterflies are also grand in scale. In the Lepidoptera taxonomic order, there are at least 15,000 butterfly species and 250,000 moth species.
