Ecological notes.

Fossorial and both diurnal and nocturnal (DOM pers. obs.). It is found in enclaves of open areas and in the brejos nordestinos (Borges-Nojosa and Caramaschi 2003), more precisely on the edge or inside forests close to watercourses (Recoder and Nogueira 2007; Macedo et al. 2008). Diet based mainly on arthropods, no information about the preferred items on the diet of this species is known. Oviparous, no detailed data is known about the number of eggs laid by the species, but it could be similar to other Cercosaura (Balestrin et al. 2010; Cossovich et al. 2011; Sturaro et al. 2018).
