Variable Reed Frog

Hyperolius concolor is a medium to large-sized member of its genus, with males measuring 24–31 mm (0.94–1.22 in) and females about 30–40 mm (1.2–1.6 in) in snout–vent length. The snout is long and pointed. The pupil is horizontal. There are two colour phases. All juveniles and many mature males display phase "J", which is normally brownish to green in colour and shows paired light dorsolateral lines or an hourglass pattern. All females, and some males, develop into phase "F" prior to the first breeding season. This phase is often colourful and variable, with uniformly green dorsum, yellow ventrum, and no dark lateral pigmentation. Also intermediate forms are found. Male advertisement call is a succession of brief, hard and non-melodic "clicks".

Hyperolius concolor is known from eastern Sierra Leone, Guinea, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, and western Cameroon (here listed from west to east).
