For many, the word migration conjures images of migrating geese in magnificent V’s flying southward in autumn, bound for exotic locales with more abundant food sources. While many bird species migrate, they are not the only groups of animals that fly south from Northern Virginia. Monarch butterfly migration is also well-known. Several other butterfly species also migrate, including Red Admiral and Painted Lady. Lesser known, and lesser understood, is the migration of dragonflies.

Of the 326 species of dragonflies in North America, only 16 are considered regular migrants. Of our local dragonfly species, Common Green Darner, Black Saddlebags, Wandering Glider and Spot-winged Glider are migratory. Migration adds another layer to the already interesting life cycle of these aerial predators.

Growing Up DragonDragonflies begin life underwater, hatching from eggs into aquatic naiads (the immature form of dragonflies). They are fierce predators feeding on aquatic insects, fish and even tadpoles.

Dragonflies undergo incomplete metamorphosis. Naiads grow larger with each molt until a final molt into adulthood. Before the final molt the naiad crawls out of water, typically perching on a rock or vegetation, then shedding its exoskeleton one final time. The new adult dragonfly rests while its wings unfurl and its exoskeleton hardens.

Adult dragonflies are amazing aerial predators. Their compound eyes, each

composed of 28,000 ommatidia

(simple eyes) provide a mosaic view, a very

efficient method of motion detection.

Dragonflies have two pairs of wings. They can move each wing pair independently of the other or, if needed, each wing independently. This trait allows them an impressive amount of maneuverability, which they use to catch their prey. In flight, dragonflies can reach speeds of 30 miles per hour, make swift right-angle turns, and stop suddenly to hover. Any flying insect is fair game, and larger dragonflies will even consume smaller dragonflies.

Migrating Dragons Continued from page 1

Generational MigrationCommon Green Darners are

the best understood of our migratory dragonflies. These

large dragonflies (almost 3 inches long) are strikingly colored with

a green thorax and a light blue abdomen. Their migration is

generational, so each adult actually undertakes a one-way journey. In late March through May, adults arrive in Reston having flown north after emerging from locations further south. These adults mate and lay eggs, dying soon after. The naiads from these eggs will develop over the summer, emerging in July and August. By September this new generation of Common Green Darners will gather in large migration swarms before heading south. After they complete their journey, the freshly-arrived adults will lay eggs and die. These eggs will produce the next generation to emerge and return north in March, starting the cycle anew.

As ectotherms (cold-blooded animals) dragonflies use the sun to warm up, orienting their bodies to maximize sun exposure on cool mornings. Fall migration will always have its share of cold mornings. The Common Green Darner has an

answer to this that produces a visible color change. Dark-colored platelets in the

blood rise to the surface in the abdomen, changing the typically

light blue abdomen to a dark purple. This dark color allows the abdomen to absorb more heat from the sun. On warm days, the abdomen remains light blue because these platelets sink below the surface, so the dragonfly will not overheat.

Our collective knowledge of dragonfly behavior and ecology still

has many holes in it, and migration is a big one. Many other species are thought to

be migratory, but there is currently not enough evidence to confirm this behavior. You can help by participating in citizen science activities like Reston’s annual Dragonfly Count. Other organizations like the Xerces Society also sponsor citizen science activities specifically designed to better understand dragonfly migration.

Directions:1. Get a mushroom from the store or carefully collect one from around your home. Make sure the mushroom is not dried out, too old or mushy. (Be sure to ask an adult for help!)2. Break off the stalk of the mushroom.3. Place the mushroom cap on a white sheet of paper with the gills down. Cover it with a bowl, and let it sit for at least 2-6 hours.4. Remove the bowl and gently lift the mushroom. You should see a pattern of spores left on the paper that have fallen out of the cap.

Mushroom Spore Prints

MAGNIFICENT MUSHROOMSBy Earl the Squirrel with help from Abby Stocking

I’ve heard it said that if you see a circle of mushrooms that fairies might be nearby. While I’ve never seen a fairy in my woods, I still find mushrooms to be quite magical things. Mushrooms are fascinating things that play a big role in the forest.

Mushrooms are part of a group called fungi. They can be many different shapes and sizes, but they all start out as a tiny spore. Like plants spread seeds, mushrooms release spores that grow into new mushrooms. Did you know that fish aren’t the only living things with gills? Mushrooms have gills underneath their caps. That is where their spores are made.

For food, mushrooms decompose, or break down, dead plants and animals. That means that mushrooms help turn dead things back into soil. By doing this, it’s like they put vitamins into the soil which plants can use to grow. Without mushrooms, we would probably not have the big oak trees that I like so much.

Mushrooms are not just helpful to plants. Many animals like chipmunks, deer, turtles and slugs eat mushrooms. Humans also eat mushrooms, but you’ll want to get yours from the store. Wild mushrooms can be poisonous to people and make you very sick.

Although most of the mushroom’s “body” is hidden underground in long strands called mycelium, fall is a great time of

year to go on a mushroom-spotting walk. I hope to see

you strolling by on the nature center trails.

If you don’t see a spore print, try it again with a new mushroom. Different types of mushrooms have different spore colors, so this activity is fun to repeat with different types of mushrooms.

Get Nuts for Clean WaterCitizens throughout the Potomac River watershed are invited to take part in a native seed collection effort. Collected seeds are donated to state tree nurseries where they are nurtured and transplanted for use in streamside and riverside reforestation.

You can help to restore native forests and protect streams one acorn at a time. When you rake the leaves, don’t throw out the acorns. Get involved in this fun activity that can be enjoyed by all.

How to help:• Collect nuts in your yard or other open areas

where they will be unable to grow. • Please do not collect at the nature center or

any natural area in Reston.• Separate the nuts by species and place

them into breathable bags (no plastic bags). Identification aids are available at the nature center and online at the link below.

• Label each bag with the kind of nuts that are inside.

• Store in a cool dry place then drop them off at the nature center.

When: Seed drop offs are accepted October 4 – 22 only.

Where: Information and collection bags can be picked up at the nature center. Please deposit bagged and identified acorns in the container on the side porch.

For more information, see www.growingnative.org or attend the following new program on Growing Native Day.

Nut Know-how: Seed IdentificationDate: Saturday, October 4Time: 10:30-11:30 a.m.Fee: $5/person RA members $7/person Non-members

Recommended for adults and children, ages 7 and up. Come for a primer on how to identify tree

nuts. Get trained on the Growing Native Program and how you can contribute

to this worthwhile citizen science project. Reservations required by October 1.

Native Spotlight: ARROWWOOD VIBURNUMViburnum dentatumBy Sharon Gurtz

Arrowwood Viburnum, or Southern Arrow-wood, is a native deciduous shrub of the honeysuckle family (Caprifoliaceae). The plant gets its name from the Native Americans who used the straight stems for arrow shafts. This plant is winter- hardy, easily grown and attractive for landscape use with its showy, white flower clusters and dark berries.

Arrowwood Viburnum is a multi-stemmed shrub with a rounded shape that grows 6 – 10’ tall and wide. It is the most adaptable of the viburnums, and can do well in sun or shade. Although able to grow in most soil conditions, it does best in loamy, neutral to acidic soils with adequate moisture. Its toothed leaves are the source of its Latin species name, dentatum. They are opposite along the branches, ovate and glossy dark-green up to 4” long. White flat-topped clusters of flowers bloom from May to June followed by blue-black, berry-like drupes in September through October.

Wildlife Shelter and FoodDense foliage provides excellent cover for small

mammals and nesting sites for birds. Many birds are attracted to this plant for cover or

its berries including the Eastern Bluebird, Northern Flicker, Gray Catbird and American Robin. Pollination ecologists have recognized it for its special value to our native bees, especially bumble bees. It is also a choice nectar source

for many butterflies, including the Red Admiral, Eastern Comma, and Question

Mark, and serves as the larval host plant for Spring Azures and Hummingbird Moths.

This viburnum may be the deer resistant shrub you are looking for to form a barrier or border, or to replace non-native plants such as Winged Burning Bush and Flowering Pears.

New Species Identified on CountDuring July’s Dragonfly Count, leader Kevin Munroe and the volunteers observed several Great Spreadwings emerging from the wetlands at Autumnwood Park. The Great Spreadwing is one of the largest North American damselflies. This species had never been seen on a Reston count. While the wings of most damselflies are held parallel to their bodies at rest, spreadwings hold them at an upright angle.
