Distribution and Habitat
Country distribution from AmphibiaWeb's database: Brazil, Colombia, Ecuador, Peru
throughout the Reserva Florestal Adolpho Ducke in Brazil.
Life History, Abundance, Activity, and Special Behaviors
The species is terrestrial
and diurnal. In the Reserva Florestal Adolpho Ducke, the diet consists
mainly of mites, ants, spiders, beetles and
crickets. Reproduction occurs mainly
between March and May. Breeding
groups form for 2-3 days in pools or seeps
near the headwaters of streams. Males
call during the day and night, and more
than 100 females can be found in one
day at a single breeding site. Breeding
groups form at different sites throughout
the season, but it is not known whether
individuals breed at different sites during a
single breeding season. Clutches contain
about 450 eggs.
similar to Dendrophryniscus minutus
in general form, but the ventral
surface of D. minutus is black at the
front, and spotted black and white
on the hind part.
