Field Workshop: Moths

July 30 @ 5:30 pm - 10:30 pm


Tuesday, July 30, 2024 from 5:30 – 10:30 PM (dinner included)
James H. Barrow Biological Field Station at Hiram College 

Instructor: Judy Semroc, Field Biologist at Nature Spark and Greg Cudworth, Naturalist 

The Land Conservancy is pleased to offer a workshop devoted to learning the identification, natural history, and behaviors of moths (Lepidoptera). Of the insect order Lepidoptera, moths make up 94% of the species, with butterflies comprising a mere 6%. They are an effective indicator of total biodiversity and species richness. Join us to learn more about these fascinating night fliers and, when the sun goes down, see them up close at the light stations we will set up in the varied habitats of the James H. Barrow Biological Field Station. A detailed schedule is below, which includes an evening of classroom time, dinner, and a moth lighting.

James H. Barrow Biological Field Station encompasses 220 acres and is protected with conservation easement held by the Land Conservancy. 

Fee: $40/person
Hiram students: Please contact Renee Boronka, rboronka@wrlandconservancy.org, for information on complimentary registration.
