| Where | Inland forests of Korea, Japan and China |
|---|---|
| Size | 18 to 23 mm body length |
| When | April to October |
This carrion beetle is black with a stronger blue sheen than its closest relative, a widespread flat carrion beetle it otherwise resembles closely in size and shape. The two are best told apart by the antennae, since this species has five enlarged terminal segments rather than four.
Adults and larvae both feed on carrion, breaking down dead animals and returning nutrients to the soil. It has a patchy, inland distribution rather than the fully coastal to mountain spread of its commoner relative.
