Frannie and the Girl Scouts had fun exploring a river for the various types of macroinvertebrates that lived there. They used nets and buckets to search for the tiny organisms!
Once a water sample was taken, Frannie and the Girl Scouts were able to look at the macroinvertebrates using magnifying glasses to help them identify which class they were from.
Check out this video of a Damselfly Naiad Frannie and the Girl Scouts found! A Damselfly Naiad is a young damselfly, and it is completely aquatic. It is a Class 2 (moderately tolerant) macroinvertebrate!
