Anindya Pattanayak, Priti R Pahari and SNP Yadav Deen
In total 19 species of Odonata larva have been recorded from a weed infested manmade Freshwater large lentic system near Tamluk, West Bengal (22<sup>0</sup>17<sup>’</sup>52.56<sup>”</sup>N, 87<sup>0</sup>55<sup>’</sup>16.72<sup>”</sup>E), India. Family Libellulidae was numerically the most abundant group comprising 66.04 % of the total Odonata larva followed by Family Coenagrionidae (31.92%) and Gomphidae (2.04%) respectively. Family Libellulidae represented by 12 species while Coenagrionidae represented by only 6 species and Gomphidae was represented by only one species. <em>Urothemis </em>and <em>Rhodothemis</em> were largest and lowest number of individuals recorded respectively. The water quality was fairly good during the 11 month study period of 2017-18. Various diversity indices were calculated in different seasons and the result shows maximum diversity and abundance during post-monsoon and minimum was in pre-monsoon. Diversity and evenness indices were fluctuated during study period due to seasonal changes of environmental conditions.
