The dominant natural larval nests of An. stephensi and An. d’thali were on river sides. Also, An. apoci was caught in these larval habitats only on the river sides. As can be seen, larval nests of anopheline species were almost similar in terms of some characteristics such as being clean and sunny and to be situated by sides of the rivers. But in the study of Azari-Hamidian in Guilan Province, anopheline larval nests had a similarity in terms of characteristics such as having clear, stagnant and temporary water.
