It feeds mainly on aquatic small insects of order Diptera and Trichoptera, foraging in 5-20cm above water surface and midium- complicated forest by trawling and aerial feeding. The latter's wave width is shortest, which have disadvantage to discriminate targets from enviroment. It feeds mainly on even smaller insects of order Lepidoptera and Diptera, foraging in wide space or sparse-foliage forest by aerial feeding.
