These grasshoppers can be anywhere between 32 and 58 mm, with females being larger than males. Their color can range from grey to brown with contrasting black and yellow-white hind wings.
Carolina Locusts are often found on or around dirt roads or paths, where they can easily blend in to gravel and soil. They prefer dry, sunny, open areas for basking, courting displays, and egg laying. Their courtship displays include flying and hovering above the open ground. These males can also call, but their sound is soft and quiet. Their flight is commonly confused for the flight of butterflies.
This species is not known to be a major pest, but some outbreaks have caused some damage in the early 20th century. Individuals of Dissosteira carolina reach over 32–58 mm in length. They tend to be conspicuous due to their... Wikipedia →

With luck
About 10% of wildlife watchers report a Carolina Grasshopper sighting in Vancouver on a given day, based on 106 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Carolina Grasshopper in Vancouver on a given day, against under 5% in October to June, the lowest months. Those are among Vancouver's driest months, with about 45 mm of rain a month against 210 mm in November.
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.
Among the best
Of the 17 cities where we can rate Carolina Grasshopper sightings, Vancouver ranks 7th at about 10%, level with the leaders once rounded. 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 Vancouver (106 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.
