LITTLETON, Colo. -- It was a perfect day for flying. Not for kites or balloons, but for butterflies.

And what better place to spread their wings than at the Denver Botanic Gardens' newest attraction, Butterflies at Chatfield Farms.

More than 300 butterflies were set free, sort of, inside a 20-foot-by-60-foot quonset greenhouse.

The butterflies were flown in from a butterfly farm in Michigan. They were shipped in breathable envelopes. They cost around $4 each.

The butterflies at Chatfield Farms are an exclusive club. Only indigenous butterflies need apply.

The attraction ends in September.
