Our First Dragonfly!


This beautiful, twelve-spotted skimmer (Libellula pulchella) emerged in our classroom on April 29! If you look closely, you can see the shell/instar/exoskeleton of the nymph. Dragonflies prefer to emerge at night. The previously aquatic nymph (also called a naiad) climbs out of the water and finds a safe place. It then goes through the final stage of its incomplete metamorphosis. The nymph’s exoskeleton will split and the adult dragonfly will begin to emerge. John and I observed emerging blue dasher dragonflies last summer in our pond. It can take from a few minutes up to a few hours for this process to be complete! After the dragonfly emerges, it will cling to the shell of the nymph and allow its wings to dry. After a few hours, the dragonfly’s wings are dry and it can fly away!

Malachi and I released our skimmer at the swamp. I hope she is doing well and is eating many mosquitoes!

If you have any questions about dragonflies, please post them here. I am no expert, but hopefully I can give you good answer!

Blue Dasher Photo #2

Here is the dragonfly after it has completely emerged, its wings are fully open and dry. You can see the instar or shedding that it has left behind. The blue dashers we watched emerging this summer all completed this process at night. Why do you think they emerge at night instead of during the day?
Dragonfly metamorphosis is different from butterfly metamorphosis.
