Diversity of moths (lepidoptera : heterocera) in selected localities on selected offshore islands and forest island habitats in Malaysia

(The diversity and vertical distribution (ground, <2m; canopy > 20 m) of the moths were investigated in tropical forests on offshore islands namely Satang Besar Island, Sarawak and Langkawi Island, Kedah and forest island habitats fragment, Kubah National Park, Sarawak and Perlis State Par...

A total of 1886 individuals comprising of 380 species and 16 families were recorded from all the sites. The highest moth species diversity was Kubah National Park (a=91.19±2.62, H'=4.65,1/D=53.87), followed by Perlis State Park (a=46.75±2.34, H'=3.88,1/D=27.01), Lubuk Sembilang, Langkawi Island (a=44.35±2.07, H'=4.08,1/D=42.44), and Satang Besar Island (a=33.87±2.09, H'=3.59,1/D=21.7).

The availability of different habitat types in an area promoting greater species diversity for different moth families to exploit, suggesting island size alone cannot be assumed to be a good predictor for species diversity.
