A nymph slowly emerges from its exuvia as a familiar adult dragonfly in this Beauty of Science video: The Metamorphosis of a Dragonfly. Wikipedia has details :. The larval stage of dragonflies lasts up to five years in large species, and between two months and three years in smaller species.

Find out more about Dragonfly Monitoring and other great citizen science projects on SciStarter! Celeste A. The Migratory Dragonfly Partnership MDP is a collaborative partnership that was set up between experts, nongovernmental programs, academic institutions, and federal agencies from the United States, Mexico, and Canada, in which citizen scientists play an integral role.

While most people are aware of the migration of monarchs and birds, most are unaware that there is also a large seasonal migration of dragonflies. The Migratory Dragonfly Partnership MDP is an organization dedicated to developing a network of citizen scientists that monitor the spring and fall movements of dragonflies five in particular. This includes monitoring migrations in Spring and Fall, Pond Watching, and collecting adults and shed casts exuviae for analysis of stable isotopes.

This dragonfly is laying eggs in our wildlife pond. This one is just sitting on the log to lay its eggs, but some species repeatedly drop down and touch the water to release their eggs. The nymph stage can last from one month to years, so some will overwinter in the pond and emerge the next year or later. These nymphs eat many other things such as mosquito eggs.

The Monarch Butterfly is the foremost example of this maneuver, but other insects migrate into northern areas from the southern states in the Spring. Crop pests are the most obvious of these migrants. Overwintering as Larvae.

Insects are creatures that have bodies with three segments that are protected by a hard shell. They have three pairs of legs and a pair of antennae. Most insects have two pairs of wings, too.

Federally endangered dragonflies that have been raised in a laboratory over the past several years are being released at a forest preserve this week in Illinois, where scientists believe they'll be a good match with the small population still there. The Hine's emerald dragonflieswhich for decades were believed to be extinct, were carefully raised at the University of South Dakota over the past four to five years after eggs were collected from a dragonfly in southwestern Wisconsin. Three out of the 20 dragonflies that could be released have already been freed so far this week at a forest preserve near Chicago.

Dragonflies are beautiful, colorful, winged insects that can grow to be up to 4 inches long. It is fascinating to watch them grow from aggressive larvae or nymphs to adults. Although it is as exciting to see the nymph change to a dragonfly as it is to see a caterpillar turn into a butterfly, keeping dragonflies as pets presents challenges. Without ample room to live, a dragonfly lifespan of several years shortens significantly due to the confines of a small environment.

Dragonflies have been around for million years, making them one of the oldest species of insects in the world. Dragonflies have been so successful over the years that the only difference between modern and ancient dragonflies is size. One of the secrets to their success is how they mature.

This week we have science activities and resources for learning more about dragonflies and damselflies, Order Odonata. Dragonflies are the large, showy insects seen around ponds and other bodies of water. They have large eyes, which often take up most of their head.
