Common Flatwing (Austroargiolestes icteromelas) lives in freshwater streams across Eastern Australia. It feeds on insects and algae. Its conservation status is Least Concern.
Fascinating facts about the Common Flatwing
- The common flatwing has a long, slender body measuring about 43 mm and is coloured a bright metallic-blue, a look shared by both sexes. Its antennae are very small while the compound eyes are comparatively large, and it does not walk with its legs; instead the legs are specialised for snatching other flying insects in mid-air.
- When at rest the common flatwing typically holds its wings spread flat, though females will sometimes fold them up. It perches on leaves close to water and, if disturbed, launches a short flight before settling again. The species is tolerant of nearby people, allowing observers to approach without causing it to flee. This resting posture and calm behaviour help it stay ready to capture prey while remaining inconspicuous among the foliage.
- The common flatwing favours habitats along streams and creeks, especially where the water runs slowly, and is rarely seen at still ponds. It tends to stay within a few metres of the water's edge, seeking shaded spots among the surrounding plants. Large groups may gather in these shaded areas, taking advantage of the cool microclimate. Such preferences tie the species closely to riparian zones where prey insects are abundant.
- The common flatwing habitually perches only a few metres away from a creek or stream, choosing shaded spots among the riparian vegetation. It often gathers together with others, forming noticeable clusters on leaves and stems within these cool micro-habitats. When something disturbs the group the insects launch a brief flight before settling again, and they remain tolerant of nearby people.
- One of the two recognised subspecies, Austroargiolestes icteromelas icteromelas, is identified by a pale labium and is confined to the southern, cooler regions of its range. The other, Austroargiolestes icteromelas nigrolabiatus, bears a dark labium and inhabits the more northern, warmer parts of eastern Australia. This geographic split mirrors the species' overall distribution across the Australian Capital Territory, New South Wales, Queensland and Victoria.

About the Common Flatwing
In the sun-drenched shallows of Australian streams, the Common Flatwing dances with an air of effortless elegance, its iridescent blue body glimmering like a fragment of sky as it flits from rock to rock. With a delicate flutter of its wings, this diminutive dragonfly navigates the water's edge, its large, jewel-toned eyes drinking in every detail of its surroundings as it searches for the perfect perch. As it settles, its wings beating in a slow, hypnotic rhythm, the Common Flatwing becomes a fleeting embodiment of the serene beauty that can be found in even the most unassuming of creatures.
