Webb2 & 3). Shannon‟s diversity indices (H) vary from 1.2 to 1.9 in all sites accounts for both richness and evenness of the insects up to or-der levels (Table 04). According to Magurran (1988), “H‟ value range between 1 to 3.5 and rarely go beyond 4.5 in natural forest. Accord-ing to the “H” value, we can suggest that the WebbShannon-Weiner Index : Species evenness, richness, and diversity indices as Shannon-Weiner (Shannon and Weaver, 1949) and Simpson Index (Simpson, 1949) were used to …
