Odonata are a captivating group of insects that include both dragonflies and damselflies. Members of this order are easily recognized by their slender, elongated bodies, two pairs of intricately veined wings, and large, multifaceted eyes. While adults are often seen skimming over water surfaces, their life story is closely tied to aquatic habitats, where their nymphs develop as efficient predators.
- Odonata means “toothed ones,” referring to the strong mandibles of these insects.
- They are divided into two suborders: Anisoptera (dragonflies) and Zygoptera (damselflies).
- Adult odonates are exceptional fliers and effective predators, capturing prey in midair.
- Immature stages (nymphs) are aquatic and use specialized gills for underwater respiration.
- Odonata serve as important indicators of freshwater ecosystem health.
- Complex Eyes and Flight
- Aquatic Nymphs
- Predatory Behavior
Odonata have two pairs of veined wings, aquatic nymph stages, and elongated bodies.
