Copiphora rhinoceros, the rhinoceros katydid, is a relatively large, up to about 7.5 cm (3 in) long, species of katydid found in Central America. It belongs to a group known as the conehead katydids, several of which have a horn-like projection on the top of the head. The horn of the rhinoceros katydid is used to ward off attacks from hungry bats. Unlike most katydids, which are herbivores, the rhinoceros katydid is an omnivore, feeding on fruit, seeds, flowers, invertebrates, frog eggs and small lizards. The species can be quite noisy during the night and produces one of the dominant sounds in Central American lowland forests. Its lifespan is one to two years.
It was first described in 1888 by Alphonse Pictet in his Locustides Nouveaux ou peu connus de Musée de Genève (New or Little-known Locusts of the Geneva Museum). Wikipedia →

Possible
About 30% of wildlife watchers report a Rhinoceros Katydid sighting in Braulio Carrillo National Park on a given day, based on 68 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 378 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February and July
In those months about 40% of wildlife watchers report a Rhinoceros Katydid in Braulio Carrillo National Park on a given day, against under 5% in November, the lowest month.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Rhinoceros Katydid sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 9 parks where we can rate Rhinoceros Katydid sightings, Braulio Carrillo National Park ranks 4th at about 30%, level with the leaders once rounded. The best odds are in Tortuguero National Park (Costa Rica, about 30%), Monteverde Cloud Forest Reserve (Costa Rica, about 30%) and Tenorio Volcano National Park (Costa Rica, about 30%).
GBIF citizen-science records
It is estimated from how often the Rhinoceros Katydid is recorded against all the insects logged in Braulio Carrillo National Park (68 verified sightings from 2019 to 2026), 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.
