Rare
Under 5% of wildlife watchers report a Migratory Grasshopper sighting in Portland on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 466th most-seen of the 507 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Migratory Grasshopper in Portland on a given day, so our monthly data shows no clear season.
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, Portland ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Salt Lake City (United States, under 5%), Vancouver (Canada, under 5%) and Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Migratory Grasshopper is recorded against all the insects logged in Portland (5 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.
