In order to record the diversity of insects in the two lakes chosen for Mysore City, a field survey was carried out. A survey performed during the month of April to June using active searching, beating leaf sampling and net sweeping techniques. Observations were made from morning 6.00 am to 11.00 am and evening 4.00 to 6.00 pm for every 10 days interval. Photographs and Results were recorded accordingly. A total of 104 individuals belonging to 10 orders were recorded. The most dominant insect order was Hymenoptera. About 28% insects are from order Hymenoptera, 27% insects are from order Hemiptera, 13% insects are from order Diptera, 6% insects are from order Coleoptera, 6% insects are from order Araneae, 9% insects are from order Lepidoptera, about 6% insects are from order Orthoptera, 2% insect was from order Odonata, 1% insect from order Zygoptera, 2% of insects from Mantodea respectively. The result shows that species richness and diversity was highest in the Karanji lake which can attribute to the high diversity of plants and availability of resources and favourable habitat structure compared to Kukkaralli lake
