Petiole 8-20 cm, glabrous; leaf blade 5-7-foliolate; leaflets sessile, abaxially green, oblanceolate, 10-25 × 5-12 cm, abaxially glabrous or with sparse whitish hairs, ferruginous tomentose at base and in axils of lateral veins, base cuneate, margin crenate-serrate with teeth crenulate-serrulate, apex acuminate to subcaudate; lateral veins in 18-25 pairs.

The former' wave width is medium. 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.

为小型蝙蝠，前者声波带宽中等，主要以水生小型的双翅目、毛翅目为食，在水面5—20cm和中等复杂的林中进行拖网和空中捕食，后者声波带宽最窄，主要以小型的鳞翅目、双翅目昆虫为食，在开阔空间内或稀疏林中进行空中捕食，视觉可能在捕食中具有重要的辅助作用。
