Friends of the Rouge will host its annual fall bug hunt on Saturday, Oct. 11, from 10 a.m. to 4 p.m. at the Plymouth Arts and Recreation Center, the Canton This Month program announced.

Volunteers search streambeds for aquatic invertebrates such as mayflies and stoneflies to help assess water and habitat quality; the presence or absence of these organisms is used as an indicator of watershed health. No prior experience is required, but all participants must register at rouge.org/bug-hunts to be assigned to a team. Children must be at least 8 years old and accompanied by a responsible adult, the announcement said.

The transcript did not specify how many sites will be surveyed during the event or whether Canton Township staff are coordinating local participation; organizers directed questions to the Friends of the Rouge website and email contact provided in the announcement.
