For anyone who has ever been told to “take a hike,” now may be the best time to do it.

The Save the Prairie Society is inviting nature lovers and fans of the great outdoors on its Firefly Night Hike at 8 p.m. Saturday. The hike, which should last no longer than an hour and a half, is open to all ages and costs $5 for general admission, $3 for seniors. Interested parties are asked to meet at the Prairie House, at 11225 Constitution Drive in Westchester.

Leading the way is John Elliott, education manager for the Forest Preserve District of Cook County. Elliott has been working with the forest preserve for over 32 years and guiding tours on and off for the past 10. He mentioned that even though fireflies are the hike’s main focus, the amount of observable wildlife that will be on display is overwhelming.

“This time of year, fireflies are one of the dusk-time features when the sun is down. We’re looking for things that happen around dusk — the changes of day to night creatures, the way birds settle down,” Elliott said. “We’ll see what there is to see and take a nice walk.”

Hikers will be able to view four or five species of firefly, all of which differ from the kind found in most backyards. There is also potential to see deer, raccoons, owls and bats, he said.

“You’re going to see stuff that you don’t see any place else in your neighborhood,” Elliott said.

Valerie Spale, the society’s executive director, said the hike is a great way for people who are looking for something unique to do with their evening. She feels the hike’s informative, interactive nature will attract people from the suburbs who normally do not have a chance at seeing the wilderness up close.

“Most people are stuck in development areas where they never leave the pavement. They’re so used to artificial light, so this gives them an opportunity to enjoy the night,” Spale said. “It’s an exciting opportunity to experience nature in a different time of day.”

Spale said the hikes are “very popular” and estimates about 40 people will be on hand for Saturday’s trek. While the hike is completely safe, sticking to a set path, those participating are encouraged to wear sturdy shoes, long-sleeved shirts, long pants and keep bug spray handy.

Founded in 1975, The Save the Prairie Society serves on the basis of saving and preserving natural wildlife habitats.
