|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).
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).
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).
