This thesis deals with a investigation of the forest night night Lepidoptera. There is in introduction a review about problemacy of coppiced and coppiced forests with standards in the relation to the day and night active Lepidoptera species. There are also presented research localities of the project TARMAG and there are introduced wider spatial relations. My particular research was done on these localities, which are under management of the project TARMAG together with ŠLP Masarykův les Křtiny. The management is like coppiced forest with standards volume of tree stands is between 4--10. During the years 2012 and 2013 I collected 8 times on each locality by using light traps, totally I collected 24 times altogether. There were collected 152 species (151 specimens of night Lepidoptera which belong to 10 families. From point of view of absolute numbers, the higher proportion of species was found in not managed stand forest, then in coppiced one. The question is, if it was due to lack of management or due other factors.
