Brief SummaryRead full entry
The polka dot tree frog (Hypsiboas punctatus) is a small (3-3.5 centimeter body length), common, neotropical treefrog in the family Hylidae. Pale green in color, its smooth skin has variable markings and can be speckled with white, yellow or reddish spots, and red or white eyelid (Boulenger 1882). Its wide distribution covers altitudes up to 1,400 m over most of the Amazon basin, including the Guianas, Surinam, Venezuela, Columbia, Ecuador, Peru, Bolivia, Brazil, and along the Río Paraguay-Parana into northern Paraguay and Argentina. It also occurs on Trinidad and Tobago. There is historic taxonomic uncertainty surrounding this species, which may contain other cryptic species within it (La Marca et al. 2010).
Hypsiboas punctatus inhabits a multitude of environment types: primary and secondary tropical and dry forests, marshes and grasslands, and also does well in degraded environments, gardens and urban areas. Adults appear to be generalist feeders, foraging on available invertebrate prey, with inclinations for dipterans (Lopez et al. 2009).
In breeding season, frogs congregate in bodies of water. Males are aggressively territorial and use an extended vocal repertoire of seven different call types to advertise for females and guard their calling site. Males also have specialized skin glands for secreting pheromones during courtship, which may influence female choice strategies and also perhaps male-male interactions. Females lay sticky gelatinous batches of 10-15 eggs, which float as a monolayer on the water surface. An individual female lays a total up to about 300 eggs (Brunetti et al. 2014, 2015).
This frog sometimes appears in the pet trade, but IUCN reports this to be at sustainable levels (La Marca et al. 2010).
