A non-profit group in Fredericton is leading a project to learn more about the insects that fly out at night and swarm porch lights.
The Nashwaak Watershed Association’s moth monitoring project asks residents in the Fredericton area to document the moths found in their yards and surrounding areas.
“The goal is just to learn about biodiversity within the watershed and in the Fredericton area,” said Allyson Heustis, the association’s executive director.
“If there’s a lot of different diverse moths, it can tell us more about other indicators in the area, like the health of the forest nearby or different plants.”
