White-snouted reed frog description
Hyperolius frontalis has a conspicuous light golden triangle adorning its snout. The rest of its body is predominately bright, translucent green, with slight mottling over a smooth back (2). Like other species within the genus, Hyperolius frontalis has expanded toe pads and fairly long legs that make it an adept climber (3) (4). The call of this species is a brief, hard buzzing, repeated two to three times (2).
- Male length: 25 – 29 mm (2)
White-snouted reed frog biology
Besides the broad ecological characteristics attributed to many species within the genus, almost nothing is known about the biology of this reed frog. In the wet season the reed frogs tend to gather near water, preferably smaller temporary water bodies, where they breed. However, very little is known of their whereabouts outside the breeding season (6). The clutch of this species comprises around 24 light green eggs in a clear jelly deposited on vegetation over water (2).Top
White-snouted reed frog range
Hyperolius frontalis occurs in the Albertine Rift, one of the richest sites for biodiversity in Africa (1) (5). Although the Albertine Rift stretches through several central African countries, this species only occurs in eastern Democratic Republic of Congo and south-western Uganda between 700 and 2,000 metres above sea level (1).Top

White-snouted reed frog status
Classified as Vulnerable (VU) on the IUCN Red List (1).Top
White-snouted reed frog threats
As with all other Hyperolius species occurring in the Albertine Rift, the distribution of Hyperolius frontalis is likely to be severely fragmented and its population, despite being reasonably abundant, is probably declining because of a decrease in the quality and extent of its habitat. Wood extraction, habitat conversion for agriculture and encroaching human settlement are thought to be the principal causes of habitat degradation in the Albertine Rift (1).Top
White-snouted reed frog conservation
There are no known conservation measures for Hyperolius frontalis but it is known to be present in at least two protected areas, Bwindi National Park in Uganda, and Virungas National Park in the Democratic Republic of Congo (1).Top
