Ochropleura implecta is a moth of the family Noctuidae. It is found from Newfoundland to South Carolina, west to Arizona, north to British Columbia. This species was described in 1998 by Don Lafontaine, who distinguished it from the very similar Ochropleura plecta which occurs in Europe and Asia.
The wingspan is 25–32 millimetres (0.98–1.26 in). Adults are on wing from April to September. There are two generations per year. The larvae feed on various plants, including beet, clover, chicory and willow. Wikipedia →

Rare
Under 5% of wildlife watchers report a Flame-Shouldered Dart sighting in Acadia National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 347th most-seen of the 405 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.
June and July
In those months about 10% of wildlife watchers report a Flame-Shouldered Dart in Acadia National Park on a given day, against under 5% in August to May, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Flame-Shouldered Dart sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
4th of 4
Of the 4 parks where we can rate Flame-Shouldered Dart sightings, Acadia National Park ranks 4th at under 5%. The best odds are in Gros Morne National Park (Canada, about 20%), Great Bear Rainforest (Canada, about 10%) and Great Smoky Mountains National Park (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Flame-Shouldered Dart that you can see in Acadia National Park (family Noctuidae, Cutworm Moths and Allies) are American Dagger (about 10%), Brown-Hooded Owlet (about 10%) and Eastern Panthea Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Flame-Shouldered Dart is recorded against all the insects logged in Acadia National Park (5 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.
