Abstract

Lycaenid butterflies (Lepidoptera: Lycaenidae) were collected during August 2014 August 2015 in the summer and the rainy season at four localities in southern areas of Nakhon Si Thammarat Mountain Ranges: Boriphat waterfall (Songkhla), Phraisawan waterfall (Trang), Panan waterfall (Satun), and Phatthalung Wildlife Breeding Center (Phatthalung). The butterflies were collected by using insect areal nets on the nature trails of an approximately 1 km. The insect collecting periods were from 8.00 - 11.00 am. and 1.00- 4.00 pm. two times per season. A total of 403 lycaenid butterflies were found. The butterflies were classified and identified into 6 subfamilies composing 57 species, Curetinae (1 specie) Miletinae (2 species) Polyommatinae (25 species) Poritiinae (1 specie) Riodininae (4 species) and Theclinae (24 species). The lycaenid butterflies were comparatively higher in number in the summer season (334) than in the rainy season (69). Species diversity, calculated by Shanon-Weiner index, in summer (H = 2.93) was significantly higher than that in the rainy season (H = 2.64) (p < 0.05). The species accumulation curve was, calculated by Estimate S (version 8.20) The number of lycaenid butterfly samples with the expected value (1st Jackknift Mean and Chao 1 Mean) approach sigmoid curve, so the number of lycaenid butterflies samples collected covered the expected value. Using PC-ORD (version 5) to determine the relationship between physical factors and relative abundance of lycaenid butterflies found that Castalius rosimon, Jamides malaccanus and Prosotas pia correlated negatively to relative humidity and rainfall, and that Caleta roxus, Rapala airbus, Paralaxita damajanti and Jamides parasaturatus positively correlated to temperature
