Teufelchen
© Clemens M. Brandstetter
(from Boudot & al. 2009:200): The range of the "Black Pennant" reaches from North Africa and the western Mediterranean through the Arabian Peninsula to central Asia. It is a strong migrant and probably has a short larval phase, which allows its reproduction in ephemeral water bodies. In addition, the larvae are able to survive under ionic stress – therefore it is able to colonize coastal as well as desert waters. In recent years S. nigra was found in several new areas and countries. Northernmost records are from the extreme north of Spain, and no more than 25 km south of the French border, the north of Italy, the east of Bulgaria, Ukraine and the southwest of the Ural. It has been recently found in Marocco, where it was discovered all along the northern Saharan margin.

Das Teufelchen, Selysiothemis nigra (Vander Linden 1825), ähnelt der Schwarzen Heidelibelle (Sympetrum danae), ist jedoch unterseits weisslich grau. Die Art besitzt fragile, "glasähnliche" Flügel. Sie ist von Nordafrika (u. a. Marokko, Boudot 2008), Malta (Corso & al. 2012) über die iberische Halbinsel, Norditalien Piemont (Subrero 2014) bis nach Zentralasien verbreitet. De Knijf & Demolder (2013) melden die Art von der Insel Kreta. Feulner & al. (2007) berichten, dass männliche Tiere in Schwärmen patroullieren während die Weibchen ausruhren. Nach Schröter (2010) kommt die Art auch in Kirgisistan vor. Im prallen Sonnenschein streckt sie den Hinterleib direkt der Sonne entgegen (Obelisk-Stellung) um einer Überhitzung zu entgehen.
Das unten abgebildete Exemplar ist ein Neufund für das Piemont!
