A. bicolor is endemic to the Riviersonderend, Du Toitsberg, Elandskloof and Limietberg mountains. It has been recorded at altitudes of 300–2000 m. The atlas records are regarded as reliable but incomplete because of the difficulties in surveying mountainous areas.
This frog is associated with moss and matted vegetation found in seepages and along heavily vegetated streams, often on steep slopes. It is known from montane fynbos where the winter rainfall exceeds 750 mm.
Breeding commences during the winter rains, and continues until the seeps dry up in midsummer. Clutches of 8–10 eggs are laid in moss or similar vegetation in seepages (Channing 2001). Males may guard the eggs as they call from oviposition sites. The eggs develop directly into 4-mm froglets. Prey consists of small arthropods.
A. bicolor is relatively widespread, occurs in several large protected areas and is in no need of special conservation action. The full extent of its distribution is not yet known.
