Thera juniperata
In 3 days ~10% in a week ~20%
The juniper carpet (Thera juniperata) is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found throughout Europe and the Near East, but is rather uncommon and locally distributed, mainly due to its very specific larval food plant. Wikipedia →

Rare
Under 5% of wildlife watchers report a Juniper Carpet sighting in Calgary on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 155th most-seen of the 256 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.
September and October
In those months about 10% of wildlife watchers report a Juniper Carpet in Calgary on a given day, against under 5% in November to August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Juniper Carpet sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
5th of 6
Of the 6 cities where we can rate Juniper Carpet sightings, Calgary ranks 5th at under 5%. The best odds are in Warsaw (Poland, about 10%), Minsk (Belarus, about 10%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Juniper Carpet is recorded against all the insects logged in Calgary (10 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.
