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...
