I haven’t featured a dragonfly on this blog yet, so I’m going to remedy that now with a rather good one. This is a female Common Clubtail (Gomphus vulgatissimus), photographed by Martyn Hall next to the River Wye at Monmouth yesterday.
|Common Clubtail, 9 June 2013, River Wye, Monmouthshire, Martyn Hall (www.martynhallphotography.com)|
The river here is a well-known site for this species, and with the good weather today, Martyn & I thought we’d give it a try. We walked north-east up the west bank from the Wye Bridge, and eventually found this individual on a stretch of the river to the north of St Peter’s church, at this location:
Older books just call this species the “Club-tailed Dragonfly” but there are several other closely-related species in Europe that this name could apply to, and this is the one with the widest range, hence the newly-coined name. In Britain, however, it’s not common at all, being confined to just eight river-systems. As well as the Wye, it’s found on the Severn, reaching downstream as far as Tewkesbury, on the Thames in Oxfordshire, the Lugg in Herefordshire, the Dee in Cheshire, the Arun in Sussex and two rivers in west Wales, the Teifi and Tywi. A slow water flow, lack of pollution, a silty river bottom, plenty of bankside vegetation and nearby woodlands are all essential habitat requirements, which explains the restricted British range.
Common Clubtail has quite a short flight period, but should be on the wing here for a few more weeks. After emerging in May, they leave the river to feed in surrounding woodlands and then return to set up territories, so numbers on the river may not yet be at their peak given the late spring. There were also around 20 Banded Demoiselles (Calopteryx splendens), but no other dragonflies on this visit, although this site does also have White-legged Damselfly (Platycnemis pennipes) later in the season.
