Renoir J. Auguste, Mike G. Rutherford


Scarthyla vigilans is a small frog in the family Hylidae (Solano 1971). It inhabits marshy areas as well as channels and ditches (Barrio-Amorós et al. 2006). Males have been known to call from relatively high perches on grasses or from on floating vegetation such as water hyacinths, whereas females typically perch on the lower parts of plants (Barrio-Amorós et al. 2006).
