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...

(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 Park, Perlis by using Pennsylvanian light traps with 576 trap-hours of
sampling efforts for each sites. 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).
Geometridae was recorded as the dominant family and species for Kubah National Park and
Satang Besar Island whereas Arctiidae for Lubuk Sembilang, Langkawi Island and Perlis
State Park. 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. The application of taxonomic diversity
measures elucidated that sites with high diversity index from species richness and abundance
accentuation are not necessarily rich taxonomically. Vertical distribution study greatly
enhances the probability of capturing the canopy fliers into collection for better interpretation
of species diversity. Six species were identified as ground stratum specialist; Omiza
lycoraria (Geometridae), Hypomecis costaria (Geometridae), Amblychia angeronaria
(Geometridae), Tasta micaceata (Geometridae), Cyana costifimbria (Arctiidae) and Cyana
malayensis (Arctiidae). Seven species were reported as new distributional records from
Peninsular Malaysia; Cispia punt fascia (Lymantriidae), Cyclosiella spiralis (Arctiidae),Hypochrosis cryptopyrrhata (Geometridae), Egnasia sundana (Noctuidae), Gracillina
