Lepidoptera of different grassland types across the Morava floodplain

Résumé fourni par la source

The occurrence of the diurnal and readily disturbed Lepidoptera species were studied during the 1992-1994 flight seasons on different types of grassland resulting from management practice: mowing, cattle grazing, and application of liquid manure.Observations were made across the southern part of the Morava River alluvia on 9 study sites.The transect method was used with 111 lepidopterous species in 15 families recorded.Five of these species are vulnerable and two species endangered.Zerynthia polyxena, Iphiclides podalirius, Colias chrysotheme, Melanargia galathea, Minois dry as, Erynnis tages, Agriphila inquinatella, Loxostege sticticalis, Zygaena loti, Zygaena angelicas, Scopula virgulata, S. immutata, Idaea spp., and Euclidia glyphica were associated with relatively well preserved xerothermic grassland habitats (no cutting history).Heteropterus morpheus, Colias hyale, Lycaena dispar, and Maculinea teleim associated with semi-annually cut and regularly flooded extensive wet meadows.Psammotis pulveralis, Elophila nymphaeata, Coenonympha glycerion, Lycaena tityrus, and Phlogophora meticulosa were found in bog habitat.The Lepidoptera community from the non-mown undisturbed areas with Crataegus sp.(foreststeppe vegetation) showed the highest diversity (H' = 2.944) and relatively high evenness (e = 0.760).The community from cut wet meadow that is heavily fertilized with liquid manure has both the lowest diversity (H' = 1.036) and evenness (e = 0.383).* Papilio machaon L., 1758 X, M * Iphiclides podalirius (L., 1758) X Pieridae Leptidea sinapis (L., 1758) * Pieris brassicae (L.,
