- Cyclommatus is a genus of the Lucanidae family, also known as the stag beetle.
- The chief distinguishing characteristics of this genus are its impressive mandibles, which can sometimes be as long as its body, as well as its lustrous metallic exoskeleton.
- Males of a larger size, or major males, relative to their respective species in this genus exhibit enlarged mandibles. These enlarged mandibles are used for scratching the surfaces of bark to allow the beetle to feed on tree sap, or to compete with other males for mates. Males with larger mandibles are more likely to win these fights, which often involves throwing the competitor off of branches and leaves.
Feeding: The preferred foods are tree saps, fruits and anything sugary.
- Temp: 15 – 30°C
