Join us for a presentation in Tyler’s Barn Loft, followed by a twilight walk to find fireflies!

Fireflies light up our yards on warm summer nights, but their glow is starting to dim as populations decline. Join native planting designer Michelle Detwiler to learn about these uniquely bioluminescent creatures and their challenges. Learn how to create healthy habitat to make your space as inviting as possible for these charismatic insects. After the presentation, we will join entomologist Sam Nestory for an exciting twilight walk to observe and identify local firefly species in the meadow at Tyler!
