Young closely resemble adults in coloration and morphology. E. jasperi is a terrestrial breeding frog. The males call from bromeliads from March through December. The female carries the growing eggs, numbering usually between one and six, in a modified fold of the oviduct during the entire gestation period of approximately one month. Nutrition for the eggs is provided by the yolk throughout development.
Eggs develop and hatch as tiny froglets.
The amount of time the young frogs stay with an adult is undetermined. Studies suggest that a female may reproduce more than one time per year. The golden coqui is found in a small restricted mountain range south of Cayey, Puerto Rico, and occupies a total habitat area of approximately 24 hectares. The coqui has to have a subtropical moist forest, receiving 1100 to 2200 mm of rainfall every year with an average biotemperature between eighteen and twenty-four degrees Celsius. Most available moisture, particularly during the dry season, comes from heavy dew condensation that is produced at night.
