Identification
Dragonflies are exotic in physignomy but can be confused with their cousins, damselflies. They are biologicaly classified in the same order, Odonata, but they are split into two distinct suborders: Dragonflies are called Anisoptera and damselflies are called Zygoptera. Simple observation of details aids identification. Dragonflies hold their wings flat and spread horizontally while perching. Damselflies fold theirs together, straight up in the middle of their backs. Dragonflies' bulging eyes either touch or appear to do so. Damselflies are generally smaller, more petite than thicker-bodied dragonflies. In the Southwest region there is a species of dragonfly that can grow to 6 inches long. Differences between male and female dragonflies may also be viewed. Female bodies have two segments, while the males divide into three. Males' genitalia are visible on most dragonflies.
Lifecycle
Female dragonflies lay their eggs directly into the warm Southwestern waters. The larvae can spend up to three years in their aquatic cradle, depending on the species. During different stages of growth and development, the individual larva sheds its exoskeleton through moulting. This process is known as "incomplete metamorphosis," as the larva does not go through a pupa stage like the butterfly or moth. The adult dragonfly transforms after the last moult, exchanging a watery nursery for an aeronautical existence. The high-soaring dragonfly will hunt food, pursue mating and reproduction while it lives the remaining summer months of its lifespan.
Territory
Territory selection is determined by a dragonfly's preference in breeding pools. They are selective creatures and will not lay eggs in polluted, murky or rapid running waters. Southwestern U.S. conservation has preserved many aquatic cultures. Male warriors fly above their kingdoms to protect breeding grounds from predators, usually other male Anisoptra of the same type. Flashing their brilliant colors sends a warning sign to intruders. When a female enters a male's domain, she is ready to mate and reproduce. After laying eggs, she leaves the breeding site until she is ready again.
Stewardship
Bitter Lake National Refuge, located northeast of Roswell, New Mexico, provides a sanctuary for dragonflies and many other unique indigenous creatures. The site was recognized in the early 20th century for its rich ecological value, and conservation efforts ensued. Environmental protection begins with good human stewardship, exemplified in the Southwestern U.S. with regard to its dragonfly population. Polluted waterways will extinguish habitats that support dragonflies and other creatures dependent on pure environments to breed and flourish. Continued efforts, like those at Bitter Lake, will help define humanity's role in nature.
