July 15, 2017 was the rare Charitable Research Reserve's community bioblitz in Cambridge, Ontario. I was a leader on a guided hike to teach participants about insects, on how to identify and collect them. We used sweep nets to collect the insects and the trail we were following took us to the Grand River. The purpose of a bioblitz is to count all the species of animals, plants, fungi and lichen in a given area, usually a park or watershed, in 24 hours.
