'Fliegenfänger' was a German operation against partisan forces in the Osmaci and Memici regions of German-occupied Albania by units of SS-Gruppenführer und Generalleutnant der Waffen-SS Karl-Gustav Sauberzeig’s IX SS Gebirgskorps (14 July 1944).

Together with 'Draufgänger' (iii), 'Röslein' and 'Sonnenstich', 'Fliegenfänger' was one of a group of operations planned and led by General Franz Böhme’s 2^nd Panzerarmee in July 1944 to prevent the concentration of partisan forces in eastern Herzegovina and the Lim river area in preparation for a movement into Serbia.

The unit entrusted with the task was the 27^th SS Gebirgsjägerregiment of SS-Brigadeführer und Generalmajor der Waffen-SS Desiderius Hampel’s 13^th SS Gebirgsdivision 'Handschar' (kroatische Nr 1), which attacked from Majevica and captured the partisan-used airfield at Osmak and the Papraći-Sekovići area from the 19^th 'Birač' Brigade of the 27^th 'East Bosnia' Division. The Germans managed to capture the airfield and damage the runway, although only slightly, and the latter had been repaired and brought back into service within one day. The 19^th Brigade managed to push back the Germans before its task was assumed by the 36^th 'Vojvodina' Division.
