[1] Egg clutches are found only from December onwards; they are glued to the inside walls of palms' dead prophylls filled with water and fallen on the ground.

[1] Blommersia angolafa occurs at four forest blocks in eastern Madagascar: Masoala, Ambatovaky, Zahamena and Betampona and occupies rain forest with an elevation range between 90 m (Ankavanana River, Masoala Peninsula) and 508 m (Vohitsivalana, RNI de Betampona).

Andreone et al. suggest that this species may also occur at other rain forest sites that fall within this elevational and latitudinal range for eastern Madagascar, such as Makira and Mananara Nord.

Andreone et al. never observed individuals outside dead fallen Dypsis phytotelmata that were lying on the forest floor or that contained rainfall.

Notes of type 2 can be short clicks consisting of a single main pulse and with a duration of 10–17 ms (n=2) or can consist of up to eight distinctly separated pulses each and then have durations of 63–86 ms, with all intermediate states occurring so that a clear distinction of further different note types is not possible.

Thus, the conservation situation for B. angolafa is potentially and negatively affected by the palms' threatened status.

The general scarcity of lentic habitats in Malagasy rain forests may have provided the conditions that favoured the evolution of this phytotelmic breeding strategy.
