Rare
Under 5% of wildlife watchers report a Spruce Zebra Beetle sighting in Edmonton on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 251st most-seen of the 390 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

In that month about 10% of wildlife watchers report a Spruce Zebra Beetle in Edmonton on a given day, against under 5% in July to May, the lowest months. That is one of Edmonton's wettest months, with about 85 mm of rain against 20 mm in February.

Of the 5 cities where we can rate Spruce Zebra Beetle sightings, Edmonton has the highest daily chance: under 5%. Next come Portland (United States, under 5%) and Calgary (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Spruce Zebra Beetle is recorded against all the insects logged in Edmonton (8 verified sightings), 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.
