Résumé :
Two of the five species of the genus Libelloides Schäffer, 1763 present in France have been observed in Alsace (north eastern France). The Black Yellow Owlfly, Libelloides longicornis (Linnaeus, 1764), was recorded from a single area in the middle of the 19th century near the commune of Sewen (Haut-Rhin) whereas the Owly Sulphu, Libelloides coccajus, is the only one to be regularly documented in Alsace. The latter was formerly observed in the dry hills of the Vosges, the Vosges valleys and the Alsatian Jura. Today, Libelloides coccajus is mainly found in about thirty communes, mainly located in the south part of the alsatian plain, in clearings in the dry forest of the northern Hardt, occasionally on embankments along motorways and also along the Rhine between Marckolsheim and Rumersheim-le-Haut. The species inhabits thermophilic environments with short, stony vegetation, from the end of April to mid-June.
