Libellula

Libellula is a genus of dragonflies in the family Libellulidae, commonly known as skimmers. The genus includes several species found in temperate regions of Europe, Asia, and North America. Notable members include Libellula depressa, the broad-bodied chaser, and Libellula quadripunctata, the four-spotted chaser. These species are often seen perched near still or slow-moving bodies of water during the warmer months.

Adults of Libellula species are typically medium-sized to robust dragonflies with stout bodies and broad abdomens. Wings are generally clear or lightly patterned, and the wing veins and pterostigmata help distinguish members of the group. They are strong, agile fliers and often patrol along the shorelines or hover over open water while hunting.

Ecology and behavior: Libellula dragonflies are predators, feeding on small aerial insects. They favor ponds, lakes, wetlands, and slow streams where they can defend territories along the water’s edge. Males establish and defend perches and territories, while females lay eggs directly into the water. The life cycle begins with aquatic nymphs, or naiads, that grow in mud and vegetation, preying on aquatic invertebrates. The aquatic stage lasts several months to a few years, depending on species and climate, after which the adults emerge for a brief, reproductive phase.

Taxonomy and notes: Libellula is part of Libellulidae, a large family of skimmers. The genus is subject to revision as new data emerges, but its members are generally recognized by distinctive wing venation and robust body shape.
