Megjegyzések:	As part of a major transformation of the EU agriculture in the last few decades, traditional land-use typesdisappeared due to either intensification or abandonment. Grasslands are highly affected in this processand are consequently among the most threatened semi-natural habitats in Europe. However,experimental evidence is scarce on the effects of management types on biodiversity. Moreover,management types need to be feasible within the recently changed socio-economic circumstances inHungary. We investigated the effects of timing and frequency of mowing on the abundance of the scarcelarge blue butterfly (Phengaris teleius), on the abundance of its host plant and on the frequency of its hostant species. In each of four study meadows, we applied four types of management: one cut per year inMay, one cut per year in September, two cuts per year (May and September) and cessation ofmanagement. After three years of experimental management, we found that adult butterflies preferredplots cut once in September over plots cut twice per year and abandoned ones, while plots cut once inMay were also preferred over abandoned plots. Relative host plant abundance remarkably increased inplots cut once in September. Management did not affect the occupancy pattern of Myrmica host ants.Invasive goldenrod was successfully retained by two cuts per year. To our knowledge, this is thefirstattempt to test management effects on the whole community module of a socially parasitic butterfly, itshost plant and host ants. Based on the results, we provide recommendations on regional management ofthe scarce large blue's habitats.
