The differential grasshopper (Melanoplus differentialis) is a species of grasshopper belonging to the genus Melanoplus. It is found throughout northern Mexico, the central United States and southern Ontario, Canada. It is considered a pest over most of its range.
Adult males grow to 28–37 mm, and females grow to 34–50 mm. They are brownish or greenish, and as they age the color will darken. Some nymphs can be bright yellow. There are black grooves on the pronotum. The male has bootlike appendages at the end of its abdominal tip. There are inverted chevrons along the hind femur, and the hind part of the tibia is yellowish with black spikes. All adults have yellow tarsi and antennae, or in some cases reddish-yellow antennae.
The differential grasshopper is found throughout most of the United States, except for the northwest. Within its range, it is most often found in heavily weeded areas and grasslands, and even in vacant lots and other urban areas. This species is not migratory, but can travel a few miles to search for food. In the northern part of its range, M. differentialis is about as numerous as the two-striped grasshopper (Melanoplus...

About 30% of wildlife watchers report a Differential Grasshopper sighting in Salt Lake City on a given day, based on 427 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 242 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

In that month about 60% of wildlife watchers report a Differential Grasshopper in Salt Lake City on a given day, against under 5% in January to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Differential 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.

GBIF citizen-science records
It is estimated from how often the Differential Grasshopper is recorded against all the insects logged in Salt Lake City (427 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.
