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).
