Rare
Under 5% of wildlife watchers report a Groove-Headed Grasshopper sighting in Sacramento on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 273rd most-seen of the 386 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.
August and September
In those months about 10% of wildlife watchers report a Groove-Headed Grasshopper in Sacramento on a given day, against under 5% in October to July, the lowest months. Those are among Sacramento's driest months, with almost no rain against 120 mm in December.
Only Sacramento, in our data
Sacramento is the only city on Wallace's Line with enough records to rate Groove-Headed Grasshopper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Acrididae
The closest relatives of the Groove-Headed Grasshopper that you can see in Sacramento (family Acrididae, Short-horned Grasshoppers) are Pallid-Winged Grasshopper (about 10%) and Gray Bird Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Groove-Headed Grasshopper is recorded against all the insects logged in Sacramento (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.
