Neurothemis tullia, commonly known as the pied paddy skimmer, is a species of dragonfly in the family Libellulidae. It is native to South and Southeast Asia, where it is frequently observed in aquatic and semi-aquatic environments.
Taxonomy and Classification
The species was first described by the British entomologist Drury in 1773. It belongs to the genus Neurothemis, a group of dragonflies often characterized by colorful wing patterns. Within the order Odonata, it is classified under the suborder Anisoptera.
Physical Description
Neurothemis tullia exhibits significant sexual dimorphism:
- Male: The male possesses a blackish-brown or velvet-black thorax and abdomen. Its wings are distinctive, featuring a broad black or deep brown base that covers roughly two-thirds of the wing area, followed by a conspicuous milky-white band. The tips of the wings are transparent (hyaline).
- Female: The female differs markedly in appearance, typically featuring a yellowish-olive or brownish body with a dark dorsal stripe. The wings are largely transparent but possess a dark, irregular streak along the costal margin and a dark brown patch at the tips (apices).
Distribution and Habitat
The species is widely distributed across the Oriental region. Its range includes India, Sri Lanka, Bangladesh, Myanmar, Thailand, Malaysia, and parts of Southern China and Indochina.
Its preferred habitats include standing water bodies such as ponds, marshes, and swamps. It is particularly common in agricultural landscapes, specifically rice paddies (paddy fields), which informs its common name. The species is often found perching on vegetation or floating weeds near the water's surface.
Behavior and Ecology
The pied paddy skimmer is generally considered a weak flier, usually staying close to the ground or water surface and making short flights between perches. Like other members of the Libellulidae family, it is predatory in both its larval (nymph) and adult stages. Larvae develop in stagnant water, while adults prey on small insects. Breeding typically occurs in the same slow-moving or still water bodies where the adults are found.
