Diversity and vertical distribution of geometrid moths (Lepidoptera: geometridae) in a peat swamp forest, Kota Samarahan, Sarawak

The diversity and vertical distribution (ground, lm and canopy, 21m) of the Geometrid moths were studied in a peat swamp forest in Kota Samarahan, Sarawak by using modified Pennsylvanian light traps. A total of 65 species from 185 individuals and four subfamilies were recorded. As might be expected...
