A difficult genus including some common species; all have one large and several small spines on the front femur. The sides of the pronotum are keeled and have a large and obvious pale spot just behind the middle. Underside characters are important in most species and specimens should be collected for reliable identification.
S. pictus is one of the largest species and the antennae are entirely pale or only slightly and gradually darkened towards the tip. Adults are usually macropterous and often have a rather brightly marked appearance in the field. The mesosternum lacks tubercles.
This species is usually found in litter piles, compost heaps or amongst plant debris. Formerly very local, in recent years it has become more frequent and is now particularly common in the London area. Adults can be found overwintering under bark.
