Club-tailed Cruiser

Macromia urania is a large dragonfly in the family Macromiidae, known as a cruiser dragonfly due to its patrolling flight behavior along watercourses. The genus Macromia is characterized by metallic greenish or yellowish markings on a dark brown or black body and bright green eyes. M. urania is native to East Asia, with records from Taiwan and adjacent parts of the East Asian region. Macromiid dragonflies breed in clean, flowing rivers and streams with good water quality, where larvae are benthic predators in swift-flowing sections. Adults are powerful, fast-flying insects that cruise steadily along forest streams and rivers, males holding territories over suitable breeding sections. Females oviposit in flight by tapping the water surface. Macromia species are generally indicators of good water quality and habitat integrity, as their larvae are sensitive to pollution and siltation. M. urania is listed as Least Concern by the IUCN. Broader threats to dragonflies in the region include water pollution, dam construction, and water abstraction, which degrade the flowing water habitats essential for Macromia reproduction.
