protoneurids
Protoneuridae is a family of damselflies belonging to the order Odonata. These insects are commonly known as protoneurids or thread-tail damselflies due to the characteristic slender, thread-like appearance of their tails. They are a relatively small family, with a worldwide distribution, but are most diverse in tropical and subtropical regions. Protoneurids are generally small to medium-sized damselflies, often exhibiting bright coloration, though some species are more subdued in appearance. Their wings are typically held together over their backs when at rest, a common trait among damselflies. The larvae, or nymphs, are aquatic and inhabit a variety of freshwater environments, including streams, rivers, and ponds. They are predatory, feeding on other small aquatic invertebrates. Adult protoneurids are also predators, feeding on small flying insects caught on the wing. Many species exhibit complex courtship behaviors and have specific habitat requirements, often preferring shaded, slow-moving water bodies with abundant vegetation. Conservation concerns exist for some species due to habitat loss and degradation of their aquatic environments.
