Bluetail Damselfly
Ischnura heterosticta
Four translucent wings frame a thread-like body marked with concentrated blue bands.
Choose your format: print it yourself, or have it delivered to you already printed, even framed.
I let the wings extend far beyond the thread of the abdomen, then kept their blue-violet membranes light enough for the venation to remain visible. The body is no thicker than a drawn line through most of its length. Saturated blue gathers at the head, thorax and selected abdominal segments, with the terminal marking giving the insect its common name. This damselfly print presents Ischnura heterosticta as a dorsal specimen study rather than a waterside scene. Its spare construction also gives the natural-history print catalogue one of its most linear silhouettes.
In shortIschnura heterosticta is the common bluetail, a widespread Australian damselfly of still and slow water. Males carry blue markings on an otherwise dark, slender body, while females occur in several colour forms. The plate shows one adult from above with all four transparent wings extended.
Key Facts
What identifies the common bluetail as a damselfly?
The common bluetail is a damselfly because it has the slender build, separated compound eyes and two similarly shaped pairs of wings typical of Zygoptera. Its abdomen is much longer than the compact head and thorax, while the four membranous wings narrow steadily from their bases. Most damselflies bring the wings together along or above the abdomen when resting, although some groups hold them partly open.
The specimen pose in the plate is not a resting posture. All four wings are extended so their venation and proportions can be compared. It displays the fine structure without pretending to be the insect’s usual position on a reed. Body build, eye spacing and similar wing shapes remain the clearest structural clues. The studio’s species cards include a short card for this plate.
Why is Ischnura heterosticta called the common bluetail?
The common name refers to the blue marking near the end of the male abdomen. Against the otherwise dark, narrow abdomen, that concentrated colour can look like a small light at the end of a wire. Male common bluetails may also show blue on the eyes, thorax and several abdominal segments, but the distal marking gives the name its clearest visual logic.
In the drawing, blue appears repeatedly rather than as one isolated dot. It moves from the rounded head through the thorax, then breaks the dark abdomen into short bands and crescents. The final blue area remains close to the pointed tip. This rhythm prevents the long body from becoming one unbroken dark stroke while keeping the terminal signal distinct.
Why do female common bluetails appear in several colours?
Female common bluetails are polymorphic, so adults do not all share one colour pattern. Some resemble blue males, while others mature through olive, brown, violet or darker forms. Age can alter the colour of an individual female, adding another layer of variation within the same species.
This range means that a single specimen cannot represent every female form. It also explains why colour alone can be misleading when the insect is seen briefly among stems. Structure, distribution and several markings need to be considered together. The blue adult in the plate records one coherent form, not a universal template for both sexes. The variation is part of the biology rather than a departure from it.
How does a bluetail damselfly spend its early life underwater?
A bluetail begins as an egg associated with water and develops as an aquatic predatory nymph. The nymph hunts small freshwater animals, moults repeatedly and remains wingless until its final emergence. A damselfly nymph carries three leaf-like gills at the end of the abdomen, where they support underwater respiration and also contribute to movement.
When development is complete, the nymph climbs a stem or another support above the surface. Its skin splits, the adult pulls free, and the wings expand before flight. There is no pupal stage. The winged damselfly then hunts smaller insects and returns to water for reproduction. The delicate adult is therefore the visible conclusion of a longer aquatic life, and its empty larval skin may remain attached near the waterline after emergence.
Where does the common bluetail live?
The common bluetail lives around still and slow water across Australia. It uses wetlands, lakes, farm dams, ponds and quiet sections of streams, usually where stems or other vegetation provide perches. Records also show tolerance of modified and mildly brackish habitats, which helps explain its broad distribution.
Adults often remain close to the water from which they emerged, although odonates can disperse between sites. Warm regions may support adult activity through much of the year, while cooler places have a more defined season. Both nymphs and adults are predators. The aquatic stage takes small freshwater prey; the adult catches insects in flight or from short sallies made from a perch.
Drawing the bluetail damselfly
I placed the specimen in a strict dorsal view with all four wings extended. The upper pair angles gently upward, while the lower pair drops into a shallow second arc. Their pale blue and lilac membranes are almost transparent, but the dense network of veins remains readable from base to rounded tip. Small brown marks along the leading edges keep the four wings from merging into one repeated shape. The open arrangement also exposes the narrow thorax between them.
The head forms a compact blue oval above a dark, copper-brown thorax. Blue stripes and spots continue down the abdomen, alternating with black-brown segments before the body narrows to a pointed end. I kept each segment distinct because the body has almost no visual mass to spare. A photograph can lose transparent wings against a light field or turn them into reflections. The hand-drawn digital illustration can hold membrane, interference colour and venation together while preserving the insect’s thread-like scale.
Where does a bluetail damselfly print work on a wall?
The narrow body and four pale wings suit a reading corner, study, quiet bathroom or lake-house hall. A thin black or pale oak frame repeats the line weight without competing with it. White, soft grey and muted blue walls keep the saturated body markings visible, while a generous neutral surround protects the fine wing edges from nearby objects. The plate belongs to The Naturalist collection, where its linear form can sit beside broader butterflies, moths and beetles. In a grouped wall, placing it between heavier specimens gives the arrangement a measured pause rather than an empty gap.
Fine-art print →Frequently Asked Questions
What makes the common bluetail a damselfly?
Its long slender abdomen, separated compound eyes and two similarly shaped pairs of membranous wings place it within Zygoptera, the damselflies. Many members of this group rest with the wings together along or above the abdomen. The open pose in the plate displays the venation rather than representing a typical perch.
Why does the common bluetail have blue near its tail?
The blue terminal marking is part of the adult male colour pattern and gives the insect its common name. Blue can also appear on the eyes, thorax and other abdominal segments. Against the dark, very narrow abdomen, the marking near the end remains the most conspicuous signal from a distance.
Are female common bluetails blue too?
Some females resemble the blue male pattern, but others occur in olive, brown, violet or darker forms. Their colours may change as they mature. That polymorphism is normal within Ischnura heterosticta, so one colour scheme cannot represent every female or every stage of adult development.
Why are the damselfly’s wings open in the plate?
The open dorsal pose exposes all four wings, their similar proportions and their fine venation. It is a specimen-study arrangement rather than a resting posture. A living damselfly commonly brings the wings together along or above the abdomen when perched, although resting positions vary among damselfly groups.
