The blue-tailed damselfly (Ischnura elegans) is a damselfly, belonging to the family Coenagrionidae. I. elegans can reach a body length of 27–35 millimetres (1.1–1.4 in) and a wingspan of about 35 millimetres (1.4 in). Adult male blue-tailed damselflies have a head and thorax patterned with blue and black, while females come in a variety of colour forms. This pair of blue-tailed damselflies was photographed while mating in Abingdon-on-Thames, Oxfordshire.Photograph credit: Charles J. Sharp
