Ynghylch

Previously known as the Club-tailed Dragonfly, the Common clubtail is a medium-sized dragonfly on the wing from early May to July. It is elusive as an adult, mostly seen on emergence from its riverine habitat. Meandering rivers with silty substrates over a rocky bed are favoured by the burrowing larvae. Adults have a tightly synchronised emergence, with dense concentrations being found at favoured sites. Once emerged, adults quickly move away from the river to woodland up to 10km away, where they spend most of their time in the canopy of trees.

Sut i'w hadnabod

The Club-tailed Dragonfly is unlikely to be confused with any other UK species because its eyes are completely separated (they do not meet on the top of its head like many other species) and it has a distinctly club-shaped abdomen. Extensive black and yellow markings are visible on both males and females, though the yellow areas on the males mostly change to green as they mature.

Dosbarthiad

Found in Southern England and Wales, but restricted to a number of rivers, including the Thames, Arun, Wye, Dee, Teifi and Severn.

Habitats

Roeddech chi yn gwybod?

The larvae of the Common clubtail live in the silt and mud of riverbeds for three to five years and have a triangular-shaped head; this makes them streamlined and difficult to dislodge.
