Lakes and ponds with vegetation and open water (Hutchings and Halstead, 2011).

seasonality
June to October in British Columbia (Paulson, 2009).

identification
Half blue and half yellow stripes on lateral sides of thorax narrow or broken into spots as the scientific name suggests (see lateral image).Most other congeneric species (e.g. A. eremita and A. juncea) have more prominent and unbroken thoracic stripes (Paulson, 2009).

life history
Females oviposit on floating vegetation. Nymphs are aquatic predators among vegetation. Adults are terrestrial and hunt insects in flight (Cannings, 2002). Adults are capable of migrating in large numbers across long distances (Catling and Kostiuk, 2008).

conservation
Common (Paulson, 2009).

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

range
Spans southern Canada from British Columbia to Newfoundland. Found as far south as Minnesota and New Jersey (Paulson, 2009).

notes
Most common of the mosaic darners (Aeshna) on the Canadian prairies (Paulson, 2009). The common name Variable Darner comes from the variability in its thoracic stripe shapes being either narrow or spotted (Cannings, 2002).
