Rare
Under 5% of wildlife watchers report a Dusky Grasshopper sighting in Dallas on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 549th most-seen of the 1412 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 Dusky Grasshopper in Dallas on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Dusky Grasshopper sightings, Dallas ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%).
Same family: Acrididae
The closest relatives of the Dusky Grasshopper that you can see in Dallas (family Acrididae, Short-horned Grasshoppers) are Obscure Bird Grasshopper (about 10%), Differential Grasshopper (about 10%) and Aztec Spur-Throated Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dusky Grasshopper is recorded against all the insects logged in Dallas (29 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.
