Possible
About 20% of wildlife watchers report an Orange-Spotted Drone Fly sighting in Kluane National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 39 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 Orange-Spotted Drone Fly in Kluane National Park on a given day, against under 5% in April–June and August–September, the lowest months. That is one of Kluane National Park's driest months, with about 50 mm of rain against 160 mm in October. January–February and November have too few records to rate.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Orange-Spotted Drone Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Orange-Spotted Drone Fly sightings, Kluane National Park has the highest daily chance: about 20%. Next come Pacific Rim National Park Reserve (Canada, about 10%) and Great Bear Rainforest (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Orange-Spotted Drone Fly is recorded against all the insects logged in Kluane National Park (9 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.
