A stag beetle that gathers on trees such as sawtooth oak and konara oak to drink sap. Its larvae grow by eating dead wood.
Its big jaws have many saw-like teeth in a row. That is where its name, meaning 'saw stag beetle', comes from.
It is active at night, but can also be seen in the shade of trees by day. It often rests high up in the trees.
