Striped Meadowhawks return to the Bow River corridor on cue
August 6, 2026
A (Sympetrum pallipes) turned up again in Varsity on August 5, the latest in a string of sightings that have traced the Bow River corridor through Cochrane, southeast Calgary, and Foothills County over the past year. What's notable isn't any single sighting but the pattern: these records cluster almost every year in the same narrow window, late August into September, which is exactly when this species should be most visible.Meadowhawks spend most of their lives out of sight. The nymphs develop underwater in ponds and slow, silty backwaters, sometimes for a full year, feeding on smaller invertebrates before crawling out onto emergent vegetation to split their larval skin and emerge as adults. Once airborne, Striped Meadowhawks are creatures of open banks and wetland margins, low fliers that perch conspicuously on bare twigs and rocks warmed by the sun, darting out to snatch small flying insects and returning to the same perch again and again. Their reddish-orange bodies and pale, unmarked legs (the trait behind the common name) make them one of the easier meadowhawks to pick out from the rest of the genus, a group that also includes the region's and s.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.
