Aeshna eremita, the lake darner, is a species of dragonfly in the family Aeshnidae. It is found in Alaska, the Northern United States and across Canada. It is similar in size and markings to the Canada darner, but has a black line across its face.
Aeshna eremita was first scientifically described in an 1866 paper by American biologist S. H. Scudder published in the Proceedings of the Boston Society of Natural History. The type specimens, fourteen males and two females, were collected in August around a site called Hermit Lake in the White Mountains of New England. Scudder provided a one-page synopsis of the colouration and morphology of both sexes. A holotype male specimen is held in the Museum of Comparative Zoology. The specific name, eremita, means "hermit" or "recluse" in Latin and refers to the site of discovery. The common name, "lake darner", refers to its common habitat of large lakes. All dragonflies of the family Aeshnidae, to which A. eremita belongs, are called "darners" in North America.
Aeshna crenata, a Euro–Siberian species, was thought by some scientists in the 19th century such as Hermann Hagen... Wikipedia →

With luck
About 10% of wildlife watchers report a Lake Darner sighting in Elk Island National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 76th most-seen of the 112 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Lake Darner in Elk Island National Park on a given day, against under 5% in August and October–May, the lowest months. That is one of Elk Island National Park's wettest months, with about 110 mm of rain against 20 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lake 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.
3rd of 5
Of the 5 parks where we can rate Lake Darner sightings, Elk Island National Park ranks 3rd at about 10%. The best odds are in Riding Mountain National Park (Canada, about 20%) and Gros Morne National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Lake Darner is recorded against all the insects logged in Elk Island National Park (8 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.
