Anax immaculifrons reaches its westernmost range limit in the east Mediterranean. The species has been found on three Greek Islands, Karpathos, Ikaria and Rhodes. It has also been found on Cyprus. On the Turkey mainland there are scattered populations along the south coast Mediterranean of Anatolia.
All records from the eastern Mediterranean are from permanent rocky streams, a few meters wide. Unlike other European Anax species A, immaculifrons does not breed in open stagnant waters. It has been found in both largely shaded and sunny habitats. The preferred substrate for the larvae seems to be gravel, sand and organic detrius sediments.
