Altogether, 53 insect species under 38 genera belonging to 17 families of the order Diptera were found in these urbanized areas at day time, out of them 10 species are under family Syrphidae, 9 species are under Muscidae and rest from the other families. So, numbers of species of the family Syrphidae were high. Peak activities of the insect were mainly observed from 8 am to 1 pm.
