In mid-June Chris Lewis received correspondence and photos from two members of the Mississippi Valley Field Naturalists regarding their recent sightings of Rapids Clubtails along the Mississippi River. A couple of these clubtails were observed along the shore at Blakeney on June 15, 2015, while one or two others were spotted at the bottom of the power station discharge channel next to Metcalfe Park in Almonte. Chris was interested in trying to track these small dragonflies down, and so on June 20th she, Mike Tate and I headed out to Almonte.
The Rapids Clubtail flies between mid-June and mid-July and is considered rare and local because of its preference for fast-moving waters along various water courses. It was first discovered in the Ottawa area by Paul Catling in mid-June 2001 when he found them at the five-arch bridge in Pakenham and at the rapids near Blakeney. In 2009, it became the first Ontario dragonfly to be added to the endangered species list; the larvae are extremely sensitive to river degradation resulting from the building of dams and increasing pollution levels. While it previously inhabited four rivers in southern Ontario, the Rapids Clubtail is now found only along the Humber and Mississippi rivers.
