Stilpnochlora couloniana is a species of phaneropterine katydid in the family Tettigoniidae, native to southeastern United States (Florida and Georgia; the only Steirodontini in the US), the Bahamas and Cuba. It is known as the giant katydid (a name also used for some other species) and it is the largest katydid in the United States, with an average length of 6.6 cm (2.6 in) in adult males and 7.8 cm (3.1 in) in adult females. Individuals from Cuba tend to grow 5–10% larger than those from the United States. They are sometimes kept as pets. Wikipedia →

About 10% of wildlife watchers report a Giant Katydid sighting in Orlando on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 294 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Giant Katydid is recorded against all the insects logged in Orlando (34 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.
