scientific name    Aeshna juncea    

common name     Rush Darner

Lakes, ponds, fens, and sedge marshes (Paulson, 2009).

June to September in British Columbia (Paulson, 2009).

Blue and yellow stripes on lateral sides thorax are straight and broad (Figure 2). Similar in appearance to Subarctic Darners(A. subarctica) but differnt by having straight thoracic stripes (instead of slightly notched). Also somewhat similar to Variable Darners (A. interrupta) but different by having broader thoracic stripes. They are easily differentiated from other congeneric species by their thoracic stripe pattern (Paulson, 2009).

life history
Females oviposit on floating vegetation. Nymphs are aquatic predators among vegetation and are mainly found in acidic waters. Adults are terrestrial and hunt insects in flight (Cannings, 2002).

Common (Cannings, 2002).

diet info
Both adults and nymphs are predatory (Cannings, 2002).

Circumpolar in boreal regions around the world (Hutchings and Halstead, 2011).

They are the most common species of mosaic darners (Aeshna) of the Yukon (Cannings, 2002).They can also be found at very high altitudes such as a lake situated in a mountain at 3,016 m above sea level (Schroeter, 2012).
