Phyllodytes luteolus (Wied-Neuwied, 1821) (Figure 1) is a species of anuran amphibian belonging to the Hylidae family. This species spends its entire life cycle inside bromeliads and is considered to have a bromeliad habit (Peixoto, 1995). They prefer bromeliads with greater complexity of structures and when they form a network connected by several individuals of the same bromeliad species (Ferreira et al., 2012; Mageski et al., 2016). Reproduction is prolonged, occurring throughout the year (Ferreira et al., 2012).
The advertisement call of P. lutelus consists of a pulsed call, with a series of notes without frequency modulation with an average duration of 5 seconds, and dominant frequencies ranging between 2 and 4 kHz (Cruz et al., 2014; Simon & Gasparini, 2003). P. luteolusmales begin vocalization activity around two hours after sunset (7 pm). The tadpoles can prey on disease vector mosquito larvae acting in the biological control of possible diseases transmitted by these organisms (Salinas et al., 2018). In addition, this species has a diet specialized in ants with pharmacological potential (Solé & Loebmann, 2017).
