Rare
Under 5% of wildlife watchers report a Dusky Grasshopper sighting in Calgary on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 167th 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
In that month about 10% of wildlife watchers report a Dusky Grasshopper in Calgary on a given day, against under 5% in October to August, the lowest months.
Among the best
Of the 4 cities where we can rate Dusky Grasshopper sightings, Calgary ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%) and Dallas (United States, under 5%).
Same family: Acrididae
The closest relatives of the Dusky Grasshopper that you can see in Calgary (family Acrididae, Short-horned Grasshoppers) are Two-Striped Grasshopper (about 20%), Green-Striped Grasshopper (about 10%) and Carolina Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dusky Grasshopper is recorded against all the insects logged in Calgary (9 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.
