Distribution ( Fig. 9 ). A common Palearctic species, occurring in Europe with the exception of the Scandinavian Peninsula and Baltic countries, but extending into Siberia. In the Maghreb, it is only present in Morocco and Algeria, collected from streams of Kabylia. In Morocco, this species was previously listed from the Rif ( Sánchez-Ortega & Azzouz 1998, Errochdi & El Alami 2008, Errochdi et al. 2014) and from eastern Morocco ( Chergui et al. 1990).

Ecology. Larvae are rheophilic occurring primarily in high altitude brooks of different sizes ( Ravizza 1998) up to 930 m in eastern Morocco and 1600 m in the Rif. However it can occur down to 10 m a.s.l. in the Rif as reported by Sánchez-Ortega & Azzouz (1998). The larvae are considered collectors-gatherers ( Hynes 1941, Brinck 1949, Azzouz & Sánchez-Ortega 2000). Capnia nigra has a univoltine life cycle with mainly winter flight period slightly extending in spring ( Sánchez-Ortega & Azzouz 1998).
