Tanzania and northern Mozambique
Warm woodland and forest mosaics in Tanzania and northern Mozambique.
Adults are active in warm daylight and visit sap or fruit.
Adults take tree sap and ripe fruit; larvae require protein-rich decaying organic matter.
Solitary.
What makes this species remarkable?
The larva can become vastly heavier than the adult, storing the resources needed to build a fully winged beetle inside the pupa.
A male’s forked head horn is a wrestling tool: rivals lever and push one another for access to feeding sites and females.
Despite its weight and armour, the adult unfolds a second pair of flight wings beneath the elytra and can fly strongly between trees.
