Possible
About 30% of wildlife watchers report a Christina Sulphur sighting in Kluane National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 39 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July and August
In those months about 40% of wildlife watchers report a Christina Sulphur in Kluane National Park on a given day, against under 5% in May and September, the lowest months. January–February and November have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Christina Sulphur 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 Christina Sulphur sightings, Kluane National Park has the highest daily chance: about 30%. Next come Banff National Park (Canada, about 10%) and Jasper National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Christina Sulphur is recorded against all the insects logged in Kluane National Park (30 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.
