ABSTRACT

From April to September 2009, to investigate the butterfly diversity in Jinyun
Mountain Nature Reserve, We selected three line-transect. A total of 1669 butterfly
individuals were collected, belongs to 9 families, 35 genera and 47 species. Of these,
the dominant species were Pieris canidia、 Pieris rapae、 Pieris melete、 Acraea
issoria, mon species were Papilio xuthus、 Papilio sarpedon、 Lethe syrcis.
The species in Nymphalidae and Lycaenidae families were the most, and they are the
dominant species. Of the 47 species, 25 species were in east asia, accounted for %
of the total; 3 species were in age-north, accounted for % of the total. 15 species
were both in east asia and age-north, accounted for % of the total. 4 species were
widely distributed over the study area, accounted for %. Fauna analysis showed that
the main elements of the fauna in this region are Oriental. Chongqing Municipality is in
the west of China, semitropical range, the distribution of butterfly reflected the
zoology-geography characteristic.
Recent studies indicate that the primory factors which impact butterfly distribution
are environmental heterogeneity, vegetation cover, temperature and human disturbance.
The temperature range is 16-34℃ in which butterfly can survive, and 23-34℃ in
which butterfly is the most active. The butterfly species and numbers are more with
higher temperature in this temperature range. The diversity indices of different months
were analysed, and the results showed that the munity diversity index
increases progressively from May to August, and drops little in September, Which was
impacted immediacy by the temperature.
Environmental heterogeneity and vegetation cover the crucial factors affecting th
