Rare
Under 5% of wildlife watchers report a Yarrow's Grasshopper sighting in San Francisco on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 263rd most-seen of the 737 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 Yarrow's Grasshopper in San Francisco on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Yarrow's 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 3 cities where we can rate Yarrow's Grasshopper sightings, San Francisco ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Los Angeles (United States, under 5%) and San Diego (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Yarrow's Grasshopper is recorded against all the insects logged in San Francisco (41 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.
