Diplacodes trivialis

A species of Perchers, Also known as Blue ground skimmer, Groundimmer

Diplacodes trivialis is small dragonfly with bluish eyes and greenish-yellow or olivaceous thorax and abdomen with black marks.

Life Cycle of Chalky percher
Egg The eggs of chalky percher are typically oval and laid in water. During this embryonic stage, they are immobile and are dependent on their protective casings to shield them from the environment.
Naiad Emerging from the eggs, chalky percher naiads are aquatic, lack wings, and superficially resemble the adult. They undergo multiple molts, growing in size, developing wing pads, and changing in coloration over time.
Adult The adult chalky percher emerges after the final molt. Distinctly marked by elongated wings and an abdomen, their vibrant colors signal maturity. The primary functions at this stage are reproduction and dispersal.

How Can You Attract Chalky percher
There is no standard use of trap food to find chalky percher as they're predatory and free-flying, but observing areas with abundant prey like small insects or near water sources might attract them for feeding.

Habitat Preferences of Chalky percher Through Different Life Stages
The eggs of chalky percher are typically laid in or near freshwater bodies, like ponds or slow-moving streams, where they adhere to submerged vegetation or detritus. naiads of chalky percher develop in these same aquatic environments; hiding in debris on the bottom, they feed on various aquatic organisms. As they grow and undergo incomplete metamorphosis, they come closer to the water surface to emerge as adults. Adult chalky percher are often seen basking in the sunshine near edges of water bodies or among vegetation, where they prey on flying insects. To observe these different stages, one would search the edges and surfaces of freshwater ecosystems, examining plants and debris for eggs and naiads, and observing open areas nearby for adult chalky percher.
Rectangle
When is the Best Time to Observe Chalky percher
The best time to find adult chalky percher is during warm, sunny days, typically mid-morning to afternoon when they're most active, while their immature stages are often found throughout the day near aquatic habitats.
Rectangle
What is the Best Weather to Observe Chalky percher
Optimal weather conditions for finding chalky percher are on warm, sunny, and calm days. Adult chalky percher tend to avoid flying in rain, strong winds, or cold temperatures.

How and Where Can You Find Chalky percher at Different Life Stages
Egg Chalky percher eggs are usually laid in or near water. To find them, carefully inspect aquatic plants, look for gelatinous masses or individual eggs attached to submerged or floating vegetation.
Naiad Naiads of chalky percher are aquatic. They can often be found in still or slow-moving waters like ponds, marshes, or the edges of streams. Look for them by gently sifting through mud, inspecting under rocks, or using a dip net in shallow water.
Adult During the emergence stage, chalky percher transition from the water to land to become adults. Look for them on vegetation near water bodies during early morning hours, as they climb onto plants to molt for the final time.
Adult chalky percher, known as dragonflies, are strong fliers and can be found in various habitats, including fields, forests, and wetlands. Search for them patrolling for food, resting on vegetation, or perching near water bodies like ponds and streams.

Chalky percher is an agile and voracious predator, both in its adult and naiad stages. With keen vision and swift flight, adults capture mosquitoes, flies, and other small insects in mid-air. Naiads ambush prey underwater. This predator's hunting ensures its survival and helps to regulate pest populations.
