Seen here is my pen and ink sketch of the Beautiful Demoiselle Damselfly (Calopteryx virgo.) This is a male with it’s characteristic inky black wings and metallic shimmering blue-green body. I saw many of these whilst fly-fishing the fast and relatively shallow River Onny in Shropshire. They flitted onto sunny perches then would glide down the river with the occasional flutter – doing circuits of what appeared to be well established flightpaths. Whilst on the perch the males would periodically flick their wings – often in response to other insects. The males themselves seemed to enjoy flying together. The river here is gravelly in it’s bottom with lush patches of vegetation on the banks providing ample perches for these chaps.
