The Summer Insect Concert: Learn the Musicians and Share the Performance with Others

Date Friday, Aug. 17
Time 3:30 - 10:30pm
Location Warren H. Corning Visitor Center
Cost $30
Description Learn to identify crickets and katydids in the daylight hours of late afternoon and the magical hours after dusk when the entire meadow is a concert hall.  Between the afternoon and evening outdoor sessions, Lisa Rainsong,will share a PowerPoint presentation featuring her own photos and sound recordings of Northeast Ohio crickets and katydids. Besides identification, this program will help you introduce these insects to participants on your own nature programs.  Learn how to find crickets and katydids, how best to catch them and how to encourage adults as well as children to participate. We will discuss the kinds of questions program participants are most likely to ask you.  Many people have not yet learned nature listening skills, so our discussion will also include how to listen for the songs. We’ll also examine these insects’ role in their ecosystems. Bring a bag dinner.

Rainsong's musical life integrates composition, education, vocal performance, and natural history.  She earned her doctorate in musical arts (DMA) in composition from Cleveland Institute of Music and is a member of CIM’s Music Theory faculty. Lisa earned a Naturalist Certificate from the Cleveland Museum of Natural History in 2008 and now teaches classes on bird song and insect song identification throughout Northeast Ohio.  In addition, she does field research on crickets and katydids – the “singing insects” – for the Geauga Park District.
