Rare
Under 5% of wildlife watchers report a Red-Cross Shield Bug sighting in Edmonton on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 159th 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 30%, if each day is a fresh chance.
June and August
In those months about 10% of wildlife watchers report a Red-Cross Shield Bug in Edmonton on a given day, against under 5% in July and September–May, the lowest months. Those are among Edmonton's wettest months, with about 70 mm of rain a month against 20 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Red-Cross Shield Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Red-Cross Shield Bug sightings, Edmonton ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%) and Seattle (United States, under 5%).

GBIF citizen-science records
It is estimated from how often the Red-Cross Shield Bug is recorded against all the insects logged in Edmonton (16 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.
