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 →

With luck
About 10% of wildlife watchers report a Flame-Shouldered Dart sighting in Great Bear Rainforest on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to July
In those months about 10% of wildlife watchers report a Flame-Shouldered Dart in Great Bear Rainforest on a given day, against under 5% in August to April, the lowest months. Those are among Great Bear Rainforest's driest months, with about 130 mm of rain a month against 480 mm in November.
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.
2nd of 4
Of the 4 parks where we can rate Flame-Shouldered Dart sightings, Great Bear Rainforest ranks 2nd at about 10%. The best odds are in Gros Morne National Park (Canada, about 20%).
Same family: Noctuidae
The closest relatives of the Flame-Shouldered Dart that you can see in Great Bear Rainforest (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 20%), Large Gray Dagger (about 10%) and American Angle Shades (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 Great Bear Rainforest (12 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.
