Description

Length: 50mm

The Common Club-tail (Gomphus vulgatissimus) is a medium sized species with a distinctively club-shaped abdomen as suggested by its common name. Females and teneral males are mainly black with extensive yellow markings on the thorax and abdomen. As the male matures most of the yellow markings turn green although the spots on the sides of abdominal segments 7-9 remain bright yellow. Unlike most dragonflies the eyes are separate and do not meet at the top of the head, which aids identification, and in mature adults the eyes are dull green.
