Melanoplus bivittatus, the two-striped grasshopper, is a species of grasshopper belonging to the family Acrididae. It is commonly found in North America, and is especially abundant on the Canadian prairies. Melanoplus bivittatus is a relatively large species with sizes ranging from 30 to 55 mm. A pair of pale yellow stripes run along the top of its body from above its eyes to the hind tip of its wings, which gives it the names two-striped grasshopper or yellow-striped grasshopper. The species often has a yellowish green coloration throughout its body due to chromoprotein and carotenoids. The rest of the body looks similar to that of most grasshopper species, with enlarged hind legs for jumping and two pairs of wings, with one set overlapping the other.
During the winter, eggs are laid in the soil and hatch by late April to early May. At optimal conditions (25 °C, very moist), Melanoplus bivittatus eggs will stop developing at around 21 days. Once development stops, the eggs go into a state of diapause, with development continuing again in spring. Once temperatures are warm enough the eggs start hatching; the maximum rate of hatching occurs between... Wikipedia →

Rare
Under 5% of wildlife watchers report a Two-Striped Grasshopper sighting in Boston on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 406th most-seen of the 1200 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.
July and August
In those months about 10% of wildlife watchers report a Two-Striped Grasshopper in Boston on a given day, against under 5% in September to June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Two-Striped 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.
9th of 15
Of the 15 cities where we can rate Two-Striped Grasshopper sightings, Boston ranks 9th at under 5%. The best odds are in Denver (United States, about 20%), Calgary (Canada, about 20%) and Montreal (Canada, about 10%).
Same genus: Melanoplus
The closest relatives of the Two-Striped Grasshopper that you can see in Boston (genus Melanoplus, North American Spur-throated Grasshoppers) are Red-Legged Grasshopper (about 10%) and Differential Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Two-Striped Grasshopper is recorded against all the insects logged in Boston (28 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.
