Melanopleurus belfragei is a small, black-colored insect belonging to the family Scarabaeidae. It is commonly found in tropical rainforests, particularly in Southeast Asia. This species is known for its distinctive horn-like projection on the head of males, which they use for combat during mating season. Melanopleurus belfragei primarily feeds on decaying plant matter and plays an important role in nutrient recycling within its ecosystem.
