Resources and Fauna of Butterflies in Jigongshan Mountain of Henan

Abstract

From May to September 2018, the butterflies community was investigated from 6 line transects of different vegetation habitats in Jigongshan mountain in Henan. A total of 2693 individuals of 113 butterfly species belonging to 70 genera and 5 families were observed. The diversity results indicated that Lycaenidae had the most individual number; Nymphalidae, with the most genera (32) and the most species (49), were dominant family in Jigongshan region; Papilio (8 species) and Neptis (7 species) were dominant genera; Colias erate (Esper), Pieris rapae (Linnaeus), Everes argiades (Pallas) and Lycaena phlaeas (Linnaeus) were dominant species. Byasa confuse (Rothschild) and Lethe syrcis (Hewitson) were first recorded in this area. The butterfly community was showed a normal distribution model of species-abundance, and the diversity index was 3.73, evenness index was 0.79, richness index was 14.18, and the dominance index was 0.11. In transects with abundant vegetation and feeble interference, all the diversity indexes of butterfly communities were higher, but dominance index. The diversity of butterfly community in Jigongshan region reached the maximum, and the dominance index was the lowest in June to July. Faunal distribution analysis showed that the widely distributed species, the oriental species and the palaearctic species was 49.56%, 31.86%, 18.58%, respectively, consistent with the transitional zone of Jigongshan mountain.
