Adults range in length from 4.5–7 mm, with oval bodies, black but with a slight bluish-green sheen.[1]

The life histories are poorly known, but they are generally found around decaying matter and fungi. S. glabratus is associated with conifer forests in northern Europe, and seems especially attracted to sap flows from trees, feeding on the sap and then mating, with the eggs laid in sap-soaked nearby soil. The larvae have a short generation span, developing into adults within a month.[1]

It is a member of Histeroidea, making it closely related to the true clown beetles. [1]
