The Neon skimmer (Orthemis discolor) is a species of dragonfly belonging to the family Libellulidae, commonly known as the skimmers or perchers. It is renowned for its striking coloration, particularly in adult males, which display a vibrant blue or violet pruinescence that gives them a luminous, "neon" appearance, especially in sunlight.
Description
Adult male Neon skimmers are characterized by a brilliant, often iridescent, blue or purplish-blue pruinescence that covers much of their thorax and abdomen. This powdery coating can make them appear almost to glow. Younger males and females typically exhibit a reddish-brown to orange coloration, which fades as males mature and develop their pruinescence. Their wings are generally clear, though some individuals may show a subtle amber tint at the base. They are medium-sized dragonflies, with an average wingspan ranging from 60 to 80 millimeters. The eyes are usually dark brown or reddish. The distinctive coloration of the males is a key identifier for this species.Habitat
Neon skimmers prefer open, sunny habitats near various types of standing or slow-moving water. These include ponds, lakes, marshes, swamps, ditches, and slow-moving streams. They are often found in areas with abundant emergent aquatic vegetation, which provides perching sites and habitat for their prey. Their presence is indicative of relatively healthy freshwater ecosystems.Distribution
This species has a wide distribution across the Americas. It is commonly found throughout the southern United States, including states such as Florida, Texas, and California. Its range extends south through Mexico and Central America, and into parts of South America, including countries like Brazil and Argentina. This broad distribution reflects its adaptability to various warm, aquatic environments.Behavior
Male Neon skimmers are highly territorial. They frequently perch on prominent sticks, rocks, or vegetation near the water's edge, using these vantage points to survey their territory and watch for potential mates or rivals. Their flight is typically swift and direct as they patrol their chosen area or chase away other dragonflies.Reproduction involves a brief copulation, after which the female oviposits (lays eggs) by tapping her abdomen onto the surface of the water, often while being guarded by the male in a tandem or hovering posture. The aquatic larvae, or nymphs, are predatory, feeding on small invertebrates such within the water column. After a period of growth and several molts, the nymph emerges from the water, usually onto emergent vegetation, to undergo its final molt into an adult dragonfly.
