Neotibicen winnemanna, commonly called the Eastern scissor(s) grinder, is a species of large bodied annual cicada in the genus Neotibicen. It is native to the Eastern United States, particularly the Piedmont Plateau and the outlying lower mountainous elevations of the Appalachians and inner, western portion of the Atlantic coastal plain.
Neotibicen winnemanna is very similar to, but ultimately distinguished from, its midwestern and coastal counterparts, Neotibicen pruinosus and Neotibicen latifasciatus, respectively. The males of each of the three species share a highly similar mating call, characterized by a crescendo of continuous pulsation. A characteristic that can distinguish N. winnemanna from the other two similar-sounding scissor grinder cicadas is its range; N. winnemanna occupies a swath of land roughly approximating the Appalachian Mountains from southern New York in the north to northern Georgia and central Alabama to the south. N. winnemanna populations do not appear to be common in maritime forests or other coastal vegetation, distinguishing them from N. latifasciatus, though they may approach the inland coastal waterways of the East Coast of the United...

Rare
Under 5% of wildlife watchers report an Eastern Scissors Grinder Cicada sighting in Washington on a given day, based on 92 verified sightings from GBIF citizen-science data. It is the 311th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report an Eastern Scissors Grinder Cicada in Washington on a given day, against under 5% in October to June, the lowest months.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Eastern Scissors Grinder Cicada sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eastern Scissors Grinder Cicada is recorded against all the insects logged in Washington (92 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.
