Dissosteira longipennis
In 3 days ~10% in a week ~20%
Dissosteira longipennis, the high plains locust, is a species of band-winged grasshopper in the family Acrididae. It is found in North America, specifically on the High Plains, consistently from eastern Wyoming and western Nebraska to eastern New Mexico and northwest Texas, and sometimes as far south as South Texas, north to Montana, and east to Iowa; it is now most common in Colorado and Kansas. During the 1930s, it formed enormous swarms and caused significant damage to crops in the western United States, but it is now very rare and has not swarmed since. However rare, the species is still extant, unlike the Rocky Mountain locust, the only other species of locust found in North America. (Excluding Central America) Wikipedia →

Rare
Under 5% of wildlife watchers report a High Plains Locust sighting in Denver on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 414th most-seen of the 461 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 High Plains Locust in Denver on a given day, so our monthly data shows no clear season.
Only Denver, in our data
Denver is the only city on Wallace's Line with enough records to rate High Plains Locust sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the High Plains Locust is recorded against all the insects logged in Denver (5 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.
