Identity and classification

Megasoma elephas (Fabricius, 1775) belongs to Scarabaeidae, subfamily Dynastinae. It was originally described as Scarabaeus elephas. [1]

Morphology and identification

The male’s pronotum and wing covers have a velvety surface. Its paired thoracic horns project forward and outward without inward-curving tips. Females retain velvety wing covers but have a rugose, hornless pronotum. [1]

Distribution and habitat

The documented range extends from southern Mexico to Venezuela. Adults inhabit tropical evergreen and deciduous forests from lowlands to about 1000 m. [1]

Feeding and host plants

Adult feeding records include sap of Lonchocarpus castilloi. Larvae have been found in standing and fallen trunks of Spondias mombin and Cedrela mexicana. [1]

Behaviour

At night, adults can cross the front tibiae like scissors to cut a twig, then feed at the resulting sap flow. Both sexes are attracted to artificial lights. [1]

Display and care

Keep the enclosure closed and display it in indirect light, away from heat and damp conditions. Handle the frame by its edges and clean only its exterior according to the maker’s instructions.
