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 →

With luck
About 10% of wildlife watchers report a Rhinoceros Katydid sighting in Cahuita National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 51 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.
January, July and November
In those months about 20% of wildlife watchers report a Rhinoceros Katydid in Cahuita National Park on a given day, against under 5% in May–June, August and October, the lowest months.
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.
8th of 9
Of the 9 parks where we can rate Rhinoceros Katydid sightings, Cahuita National Park ranks 8th at about 10%. 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 Cahuita National Park (12 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.
