Mayfly Larva can be seen in fresh water bodies such as streams, ponds or lakes throughout BC. They like to eat algae and are about 30mm in length.
The best way to identify them is to look for their three-pronged abdomen tail and their fuzzy gills that line their sides.
When Mayflies emerge as adults, they generally live just a single day. Then they shed their skin again, wings and all, and become a true adult and this life is also short lived as well.
