Rare
Under 5% of wildlife watchers report a Migratory Grasshopper sighting in Seattle on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 212th most-seen of the 428 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 Migratory Grasshopper in Seattle on a given day, against under 5% in October to August, the lowest months. That is one of Seattle's driest months, with about 60 mm of rain against 190 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Migratory Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Migratory Grasshopper sightings, Seattle ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Salt Lake City (United States, under 5%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Migratory Grasshopper is recorded against all the insects logged in Seattle (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.
