Een van de mooiste kikkers van Peninsula Osa is wel de kleine nachtactieve boomkikker Hyla ebraccata, die zeer variabel van kleur en tekening is. De auteurs hebben deze dieren veelvuldig mogen observeren en fotograferen. Zo ontstond er bijvoorbeeld een serie foto’s vanaf de amplexus totdat er weer nieuwe kikkertjes aan de kant kwamen.

Hyla ebraccata Cope, 1874

Hyla ebraccata is a moderately small frog and a jungle jewel much favoured as a photographic subject because of its usually vivid dorsal coloration of one or more bold dark brown blotches. Adult males are 23 to 27 mm in standard length, adult females 30 to 35 mm. They are typically found around temporary ponds in lowland moist and wet forests and premontane wet forest. They are nocturnal and the males usually call from emergent vegetation in the ponds. Axillary amplexus takes place outside of the water, and eggs are laid above the water in a single layer on leaf surfaces. The metamorphosis takes place in about 3 to 4 months.
