The elephant beetle (Megasoma elephas) is a member of the family Scarabaeidae and the subfamily Dynastinae. Elephant beetles are Neotropical rhinoceros beetles. Elephant beetles are black in color and covered with a coat of fine microscopic hairs. The hairs grow particularly thick on the beetle's elytra, and give its body a yellowish color. Males have two horns protruding from the head and another from the prothorax. The longest head horn gives the beetle its common name, since it resembles an elephant’s trunk. Females have no horns. The horns are used for defense, and in competition among males for food and mates.
In size, elephant beetles typically range between 7 and 12 cm (2.75–4.75 in), with the largest male specimen known measuring 13.7 cm, including the horn. Elephant beetles are located in southern Mexico, Central America, and in South American rainforests.

GBIF citizen-science records
It is estimated from how often the Elephant Beetle is recorded against all the insects logged in Arenal Volcano National Park (11 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.
