Myra: I used roof flashing and cut the wing shapes. I have also used decorative hinges, metal strapping, wire and anything else I find. You have to modify the screw plates sometimes to fit onto the body and then get creative with spray paint!

We cut the bracket off one side of the blades and it fit perfectly on the table leg. We used some screws on circle hooks on the back for mounting. Brenda K. Jeanne Sammons found these Barbed wire dragonflies on a garden walk. Jimmye Lynn Dye-Porter made a little bee from a bottle. I painted the interior yellow, then striped the outside with the black, made the wings from copper wire and used a small flat gemstone for the face. I hope you try finding the pieces needed to make your own good luck charm.

Thanks for the ideas. Amongst Native Americans, it is a sign of happiness, speed and purity. Purity because the dragonfly eats from the wind itself. The name Horse Stinger comes from the misinformed observation that horses that were kicking and stamping around usually had a few dragonflies hovering around them. For a species of insects that have inhabited our planet for almost million years, it is only natural perhaps that they have such a wide and varied perception amongst various civilizations.

A Dragonflies ability to manoeuvre in many directions makes them able to out-fly their prey. Dragonflies also have the advantage of excellent eyesight. Each of their two large eyes is made up of thousands of six-sided units. Together, these smaller eyes enable a dragonfly to detect even the slightest movement. A dragonfly undergoes incomplete metamorphosis.

Female dragonflies lay eggs in or near water, often on floating or emergent plants. When laying eggs, some species will submerge themselves completely in order to lay their eggs on a suitable surface. After about two weeks, the eggs hatch and an immature dragonfly, or nymph, emerges. The nymphs are not as attractive as the adults. They have tiny wings and a large lower lip, which they use to catch their prey often mosquito larvae.

Dragonfly nymphs live in the water. As they grow, they molt shed their skin. Nymphs of some species may take as long as three years to mature.

Most of a dragonflys life is spent in the larval stage beneath the waters surface, using internal gills to breathe and using extendable jaws to catch other invertebrates or even vertebrates such as tadpoles and fish. Birds and other predators consume a significant number of young dragonflies in the first few days after their emergence.

Relative to other insects, dragonflies have extraordinarily keen vision that helps them detect the movement of other flying critters and avoid in-flight collisions. Dragonflies are able to move each of their four wings independently. They can flap each wing up and down, and rotate their wings forward and back on an axis.

Dragonflies can move straight up or down, fly backward, stop and hover, and make hairpin turns—at full speed or in slow motion. A dragonfly can fly forward at a speed of body lengths per second up to 30 miles per hour. Competition for females is fierce, leading male dragonflies to aggressively fend off other suitors.

In some species, males claim and defend a territory against intrusion from other males. Skimmers, clubtails, and petaltails scout out prime egg-laying locations around ponds.

Should a challenger fly into his chosen habitat, the defending male will do all he can to chase away the competition. Other kinds of dragonflies don't defend specific territories but still behave aggressively toward other males that cross their flight paths or dare to approach their perches.

In nearly all insects, the male sex organs are located at the tip of the abdomen. Not so in male dragonflies. Their copulatory organs are on the underside of the abdomen, up around the second and third segments.

Dragonfly sperm, however, is stored in an opening of the ninth abdominal segment. Before mating, the dragonfly has to fold his abdomen in order to transfer his sperm to his penis.

A number of dragonfly species are known to migrate, either singly or en masse. As with other migratory species, dragonflies relocate to follow or find needed resources or in response to environmental changes such as impending cold weather. Green darners, for example, fly south each fall in sizeable swarms and then migrate north again in the spring.
