| Abstract |
Relicts of East-Flemish inland dunes were investigated for the presence of dune-land fauna. Five of the 8 therevid species known from Flanders were found in the present study. In contrast to asilids, therevids showed to be pioneer species preferring areas with large bare sandy patches. Pit fall traps proved to be twice as effective to sample therevids than white or yellow pan traps. Yellow traps are ineffective. Highest activity and diversity is found in June and July. |
