Megatibicen dealbatus, commonly called the plains cicada, is a species of annual cicada. Dealbatus is Latin for "whitewashed". This species used to be called Tibicen dealbatus, but in July 2015, after genetic and physiological evaluation and reconfiguration of the genus Tibicen, this cicada and others in the genus Tibicen were moved to newly created genera. Furthermore, the genus Tibicen still exists, but today it only encompasses a small number of European taxa.
M. dealbatus adults have beige-colored eyes. and like many other cicadas in the genus. have a distinctive black "mask" that extends from each of the cicada's bulging eyes. This species' pronotum is light orange or olive green. The coloring of its mesonotum is orange, green, black, or brown with three white pruinosity areas on the dorsum separated by stripes.
This species may be confused for a superficially similar, but distantly related Megatibicen species: Megatibicen dorsatus. Certain overlapping diagnostic traits are found in both cicadas, such as the pruinose patterning on the abdomen and narrow head. This can complicate accurate identification or lead to erroneous reports, but the call... Wikipedia →

With luck
About 10% of wildlife watchers report a Plains Cicada sighting in Denver on a given day, based on 180 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 461 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Plains Cicada in Denver on a given day, against under 5% in November to June, the lowest months. That is one of Denver's wettest months, with about 50 mm of rain against 15 mm in January.
Only Denver, in our data
Denver is the only city on Wallace's Line with enough records to rate Plains Cicada sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Plains Cicada is recorded against all the insects logged in Denver (180 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.
