With luck
About 10% of wildlife watchers report a Spruce Zebra Beetle sighting in Jasper National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 72nd most-seen of the 88 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.
June to August
In those months about 10% of wildlife watchers report a Spruce Zebra Beetle in Jasper National Park on a given day, against under 5% in September to May, the lowest months. Those are among Jasper National Park's wettest months, with about 110 mm of rain a month against 55 mm in April.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Spruce Zebra Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Jasper National Park, in our data

GBIF citizen-science records
It is estimated from how often the Spruce Zebra Beetle is recorded against all the insects logged in Jasper 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.
