The variable darner (Aeshna interrupta) is a dragonfly of the family Aeshnidae, native from Alaska through the Northwest Territories to Newfoundland, south to New Hampshire and Michigan in the eastern United States, and to the mountains of New Mexico, Arizona, and California in the west. It's named after the distinctive broken stripes on the sides of the thorax of many male specimens. It lives in many habitats from northern and mountain peatlands to cattail marshes and temporary pools. It is the characteristic species of grassland ponds. Wikipedia →

With luck
About 10% of wildlife watchers report a Variable Darner sighting in Banff National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 76th most-seen of the 105 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Variable Darner in Banff National Park on a given day, against under 5% in October to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Variable Darner sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Variable Darner sightings, Banff National Park ranks 6th at about 10%. The best odds are in Riding Mountain National Park (Canada, about 20%), Elk Island National Park (Canada, about 10%) and Grand Teton National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Variable Darner is recorded against all the insects logged in Banff National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
