Calopteryx atrata

Calopteryx atrata

Calopteryx atrata

A species of Demoiselles

Cloaked in metallic hues, calopteryx atrata flutters along streams and rivers in a graceful ballet. Sporting iridescent wings that glimmer in sunlight, this species is adept at aerial maneuvers, capturing equally agile prey mid-flight. As larvae, they lurk underwater for up to two years, morphing into winged adults that continue to play a crucial role in their ecosystem as both predator and pollinator.

Life Cycle of Calopteryx atrata
Egg The egg of calopteryx atrata is often laid in water or on vegetation near water. It is generally oval and small, changing over time from a lighter to a darker shade as it matures.
Naiad Emerging from the egg, the calopteryx atrata naiad resembles a small adult without wings. The aquatic naiad molts multiple times, growing larger and developing wing pads as it ages.
Adult Transitioning from nymph to adult, the calopteryx atrata exits the water. The final molt reveals wings and reproductive structures. The newly emerged adult's color intensifies, and it often relocates to terrestrial habitats to feed and mate.

How and Where Can You Find Calopteryx atrata at Different Life Stages
Egg Calopteryx atrata eggs are typically laid on vegetation near or in water. Look for them on plant stems or leaves that are partially submerged or on the water's surface.
Naiad Calopteryx atrata naiads are aquatic and can be found in ponds, streams, or other bodies of fresh water with vegetation. Search for them by carefully investigating submerged rocks, leaves, and stems.
Adult During emergence, calopteryx atrata transition from naiads to adults. This stage occurs near water bodies where naiads are found. Spot them by looking for exuviae (shed skins) on plants or structures near water or for newly emerged adults drying their wings.
Calopteryx atrata adults are often seen around water bodies such as streams, rivers, and lakes, where they hunt for insects, mate, and lay eggs. They can be found perching on vegetation or flying swiftly over water. To locate them, walk slowly along the banks of such habitats and observe for their distinct flight patterns and vibrant colors.
