Caucasian goldenring  (Cordulegaster mzymtae)

Description

Also referred to as spiketails and biddies, golden-ringed dragonflies (Cordulegastridae) are large black dragonflies with generally bright yellow rings more or less encircling their abdomen, depending of the species (2) (3). The Caucasian goldenring is one of the darker species of the genus and shows only small yellow marks on the abdomen, although it exhibits the typical thoracic yellow bands of most of the golden-ringed dragonflies. It has large green eyes. Males and females are similar in appearance. Reliable separation from the other Turkish golden-ringed species, C. insignis, is mainly possible through the more squarish and flat back part of the occipital triangle (ovoid and swollen in insignis) and its greenish eyes (generally bluish in insignis), supporting its status of distinct species (2).
