Mecynorrhina oberthuri unicolor (also spelled Mecynorhina) is a large, highly sought-after subspecies of flower beetle native to the tropical rainforests of Tanzania and Central Africa. It is a color variation of the "Tiger Flower Beetle" (Mecynorrhina oberthuri) specifically prized for the absence of standard black patterning on its back.
 
Physical Characteristics
Coloration: Unlike the "decorata" form which has a ripple pattern of orange and black, the unicolor variety features a solid, glossy pumpkin-orange or copper-toned elytra (wing covers).
Sexual Dimorphism: Males possess large, forked horns used for territorial battles, while females are hornless and generally smaller.
Size: Adults typically range from 50 mm to 70 mm in length. 
 
Behaviour and Life Cycle
Activity: They are diurnal, meaning they are most active during the day.
Larval Stage: Larvae develop in a substrate of decomposing wood and leaf litter. In captivity, they construct soil cocoons for pupation, which can sometimes be seen attached to the walls of their container.
Diet: Adult beetles feed on sweet, soft fruits such as bananas, mangoes, and apples, or specialized nutrient-rich beetle jelly. 
 
Captive Care (as of 2026)
As of early 2026, these beetles remain a "very rare" and popular species in the exotic pet trade due to their vibrant colors and impressive size. 
Temperature: They thrive in warm environments, ideally between 22–28°C.
Humidity: High humidity (70–80%) is required to mimic their native tropical habitat.
Substrate: Larvae require a deep layer of decayed leaf mold and white-rot wood for both nutrition and burrowing.
