Cyrano Darner
Nasiaeschna pentacantha (Rambur, 1842)

Threats [-]
Land use practices which might damage shoreline vegetation and floating and/or emergent vegetation in breeding waters could make the habitat less suitable. Also, run-off from surrounding lands that might lead to lower dissolved oxygen, such as fertilizers, could also reduce favorable conditions.

Conservation Strategies and Management Practices [-]
Lakeshore practices such as natural buffers that promote shoreline integrity of forests and healthy stands of native emergent and floating vegetation should serve to benefit populations of this species.

Research Needs [-]
There is very little known about most aspects of this species' life history and population dynamics. The large distinctive adult dragonfly is rarely encountered, although exuviae can be surprsingly common (Pollard and Berrill 1992), which suggests it could be under-reported.
