Most species in the genus Epinecrophylla are similar to one another: small brown antwrens, the males of which have throats that with a black and white "checkered" pattern. The Brown-bellied Antwren is the only member of the genus that occurs in the Guianan region, north of the Amazon and east of the Rios Branco and Negro. Singles, pairs, or family groups forage in the under- and midstory of lowland forest and adjacent second growth, usually as members of mixed species flocks that include other species of antwrens (Myrmotherula), antshrikes (Thamnomanes), and other insectivorous birds. As is typical of all species of Epinecrophylla, the Brown-bellied Antwren searches for arthropods that are hidden in curled, dead leaves that are trapped in vine tangles and other sites above the ground.
