Japanese rhinoceros beetle

Trypoxylus dichotomus is a large scarab beetle (Scarabaeidae) with marked sexual dimorphism: males reach 40–80 mm including a long, upward-curving, forked head horn and a shorter forked thoracic horn, whereas females measure 35–60 mm with rudimentary horns. Adults are dark brown to blackish and weigh about 5–10 g. It ranges from Japan and the Korean Peninsula through central and southern China to Taiwan and mainland Southeast Asia, inhabiting deciduous broadleaf and oak woodland. Larvae feed on humus, leaf litter and rotting wood for about ten months; adults take tree sap and overripe fruit. It remains unassessed by IUCN.
