On May 30th I met with Chris Traynor for a morning of bug-hunting in the west end. My main goal was to look for River Jewelwings, a damselfly that I see much less frequently than the similar-looking Ebony Jewelwing. Both of these broad-winged damselflies (genus Calopteryx) breed in the flowing waters of medium-sized creeks and streams, particularly in forested areas. While Ebony Jewelwings are most commonly found in shallow, shady streams with much emergent vegetation, River Jewelwings prefer swifter and somewhat rocky streams. There aren’t too many streams I would characterize as “rocky” in Ottawa’s west end (they are more common up in the Gatineau Hills); indeed, I have found only one stream inhabited by these colourful damselflies: Watts Creek near Shirleys Bay, on the south side of Carling Avenue. However, the bank is very steep where I have seen them – it is about a five- or six-foot vertical drop to the water, and the top of the stream bank is too thickly vegetated to walk along in order to find another spot with a shorter drop. This makes photographing them quite difficult, as they like to perch on vegetation close to the water.
