Rare
Under 5% of wildlife watchers report a Carolina Grasshopper sighting in Baltimore on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 374th most-seen of the 705 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.
June–July and September
In those months about 10% of wildlife watchers report a Carolina Grasshopper in Baltimore on a given day, against under 5% in August and October–May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Carolina Grasshopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 17
Of the 17 cities where we can rate Carolina Grasshopper sightings, Baltimore ranks 14th at under 5%. The best odds are in Edmonton (Canada, about 10%), Montreal (Canada, about 10%) and Denver (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Carolina Grasshopper is recorded against all the insects logged in Baltimore (12 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.
