The dragon fly is common in the spring and summer months. Eggs are laid in the water and develop into a larva stage that remains in the water until ready to emerge as the adult. The larva are carnivorous and as they mature they become excellent swimmers. Dragon fly larvae are sensitive to low dissolved oxygen levels and therefore can act as an indicator of water quality. The two pictures above are of a dragon fly larvae caught in October at creek site #4 and raised in an aquarium in Mr. Thiels classroom. The second picture is the same organism three weeks later.
