Firefly Chemistry, Campfire

Have you ever witnessed a field of small insects that light up at night? How is it possible for a critter to produce light? Join a naturalist by the fire from 7 to 7:30 p.m. Saturday, June 3 to learn about the unique characteristics of fireflies. Bring along your camp chairs and s’mores for the fire. Meet at the grass lawn by the Lake Itasca Fishing Pier, below Douglas Lodge.
