The Blue-tailed Damselfly, Ischnura elegans, is an European damselfly.
Adult male Blue-tailed Damselflies have a head and thorax patterned with blue and black. They have a largely black abdomen with very narrow pale markings where each segment joins the next. Segment eight, however, is entirely pale blue. Female Blue-tailed Damselflies come in a variety of colour forms, including a pink form, a violet form and a pale green form. Purple/violet, pink and green forms are juvenile, with the colour darkening as the damselfly ages. Mature female damselflies are usually brown/green, or blue which is an andromorph form.
