Join the Missoula Butterfly House & Insectarium at the spectrUM Discovery Area to meet and hold friendly Bug Ambassadors, learn a bit about what bugs do to survive the cold winter months and make a bug ornament to add to your tree. This activity is free but normal spectrUM admission rates apply. Admission is $3.50 for people four years and older, kiddos three and under are free. Thanks to spectrUM’s participation in the Museums for All program, families with an EBT card get in free.
