The back and sides of this frog are yellow-green, whilst the underparts are black with blue spots. The legs are green, and the hind limbs may be banded, but there is no webbing between the toes. A light stripe runs along the upper lip (2).
This frog is mainly diurnal and eats small insects which are attracted by fallen fruits. Males attract females by calling out very short notes that are composed of two even shorter clicks. Between 15 and 60 greenish-yellow eggs are laid (3) in cavities under rocks and in the trunks of dead trees (4). They hatch into tadpoles during heavy rainfall, which washes them into small pools of water (4). The tadpoles grow to a size of 28 mm and undergo metamorphosis after 45 – 65 days to take the adult form (3).
The green mantella is found in the Montagne des Francais in northern Madagascar, as well as in the Massif of Antogombato, south of Diego, Madagascar. It is found at elevations of 50 – 300 m above sea level (1).
Having suffered over-collection for the pet trade in the past, populations of green mantellas are now most threatened by habitat degradation. The green mantella is still locally abundant, but it exists in a very small range and so is at risk of extinction if its habitat is not protected from the fires, selective logging, firewood collection and livestock grazing that currently threaten it. Too much forest loss will have cumulative effects as the streams could dry out (1).
Trade regulations have successfully reduced collection of this species, but trade must continue to be carefully controlled to ensure its survival. It does not occur in any protected areas, but it is sometimes bred in captivity (1).
