Possible
About 20% of wildlife watchers report an Unmarked Dagger sighting in Gros Morne National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 83 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report an Unmarked Dagger in Gros Morne National Park on a given day, against under 5% in February–May and August–December, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Unmarked Dagger sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Gros Morne National Park, in our data
Gros Morne National Park is the only park on Wallace's Line with enough records to rate Unmarked Dagger sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Unmarked Dagger is recorded against all the insects logged in Gros Morne National Park (17 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.
