Sepsis Fallén, 1810

This is the most species-rich and commonly recorded clade of Sepsidae in Switzerland.Species of Sepsis are characterized by ablack spot near the tip of the wing, although some species that do not occur in Switzerland lack this characteristic. Most species breed in animal dung and are an essential part of the European cow dung fauna. Often, six to seven species co-occur on cow pastures, but up to twelve species have been recorded in Lenzerheide GR ( Rohner et al.2014). The high degree of sympatry suggests some degree of spatio-temporal niche separation, which is poorly understood but begs for scrutiny.
