Join us as we venture out on the trail at dusk listening for musical and mechanical insect sounds.  Many insects become more active as the sun goes down.  We’ll listen and learn the distinct sounds of common local species and why they make these sounds. Participants should be prepared to walk more than 2 miles outdoors on natural surface trails across uneven terrain.
