This large carpenter bee has a smooth, glossy black body with dense yellow or whitish hair on the thorax, contrasting with mostly black hair elsewhere; adults measure roughly 20 to 30 mm in length.

Females chew tunnels into dead wood to nest and provision their brood cells with pollen, while both sexes visit a wide range of garden and wild flowers; adults are active from spring into autumn across Japan, Korea and China.
