Blue Morpho butterflies have arrived at the Sophia M. Sachs Butterfly House at Faust Park, 15193 Olive Blvd., Chesterfield, to celebrate the sights and sounds of Mardi Gras.

Thousands of Blue Morpho butterflies will flood the conservatory during the Morpho Mardi Gras. The exhibit hall, which features a variety of invertebrates, will be decorated in a Mardi Gras parade motif, and visitors will have the opportunity to make their own masquerade mask.

Blue Morphos are native to the forests of Central and South America. They are one of the largest butterflies at the Butterfly House with a 6-inch wingspan.

Their blue wings are lined with tiny scales that allow only blue light to escape, resulting in their blue appearance.

Throughout February and March, visitors will learn more about this creature, and the role butterflies play in nature through interpretive signage in the conservatory and exhibit hall.

Friday Night Flights

Also in February and March, the Butterfly House will host adult visitors for Friday Night Flights on Feb. 3 and March 3 from 5:30 to 7:30 p.m.

If you can’t travel to New Orleans, you can still celebrate like a member of the Krewe of Morpheus in Chesterfield. Dine on appetizers from Championship Catering and sample wines and other libations, from Total Wine & More, in the midst of live jazz music from the National Blues Museum.

Meet Daisy, the adorable fennec fox, from the Endangered Wolf Center and see the glass Blue Morpho Butterflies, created by artist Craig Mitchell Smith.

Reservations should be made in advance.

Hours at the Butterfly House are 10 a.m. to 4 p.m. Tuesdays through Sundays (closed Mondays). The last ticket is sold 30 minutes prior to closing each day.
