Indonesia Species Profile of Vestalis luctuosa (Odonata: Calopterygidae)

Abstrak

Vestalis luctuosa is a species of damselfly from the family Calopterygidae, commonly found in the tropical forests of Southeast Asia, including Indonesia. V. luctuosa typically inhabits small, shallow, and shaded forest streams with relatively calm flow. This species is often seen perching on twigs or low leaves near the water surface, and the females lay their eggs on plants growing along stream edges or on submerged vegetation. This damselfly also has significant potential as an indicator of water quality because its presence is highly dependent on clean and stable stream conditions, making population changes a reflection of local environmental health. In addition, V. luctuosa provides important ecosystem services for humans and the surrounding environment, especially as a predator of small insects. In agricultural contexts, damselflies are often considered natural enemies of pests because they prey on various types of crop-damaging insects
