was observed on September 30 at Fish Creek Park and September 19 in Calgary.1 These dragonflies require clean, well-oxygenated water and their presence indicates pollution-sensitive aquatic conditions suitable for their development.1

That this species keeps showing up here matters more than the individual count. iNaturalist flags Sympetrum pallipes as a species of conservation concern, so a presence record repeated year after year, in the same season, along the same stretch of river, is meaningfully different from a one-off sighting. These are still just presence records, not a census, so nothing here shows whether the local population is growing or shrinking, only that the corridor keeps supporting a full life cycle for the species season after season.
That continuity lines up with what a broader 30-day survey of the same stretch turned up: a mixed assemblage of odonates including
and various darners in the genus
, alongside riparian fish like
and
. That combination, damselflies and dragonflies needing clean still water to complete metamorphosis, fish needing cool moving water and intact banks, is the signature of a riparian system that is still doing the job wetlands and slow-water edges are supposed to do.
