Mechynorrhina torquata immaculicollis is a dazzling subspecies of giant flower beetle native to tropical Africa, particularly Cameroon and the Congo Basin. Renowned for its metallic green sheen and impressive size—males can reach up to 85 mm—it belongs to the Goliath beetle group within the Scarabaeidae family. Males sport a prominent horn used in mating displays and territorial battles, while females are more compact and adapted for burrowing.
This subspecies is distinguished by its smooth, unmarked pronotum (“immaculicollis” meaning spotless neck), setting it apart from other Mechynorrhina variants. In captivity, it’s a favorite among breeders for its manageable care needs, communal larval tolerance, and striking adult appearance. Adults feed on soft fruits and beetle jelly, while larvae thrive in deep, moist substrate rich in decaying leaf litter. With proper care, they offer a rewarding display of beetle grandeur and gentle behavior.
