Common name

Stauffer's Treefrog, Stauffer's Long-nosed Treefrog

Identification

Adult

Species description based on Savage (2002). A small treefrog with a long, pointed snout (males to 29 mm, females to 32 mm).

Dorsal

Dorsal coloration greyish or brownish, with some darker spots or blotches. The arms and legs are barred. The sides of the body are cream-colored or pale brown. The dorsal skin is tuberculate.

Ventral

Ventral coloration is dingy white.

Concealed surfaces

The rear surfaces of the thighs are brown.

Eye

The iris is brownish or bronzy.

Life history

Breeding season

Breeding occurs in temporary pools that fill with rain during the rainy season (Savage 2002). Males call from low vegetation or the ground (Savage 2002). Large numbers of individuals congregate at ponds after heavy rains (Savage 2002).

Egg

Eggs are laid in small clumps in shallow water (Savage 2002).

Tadpole

The tadpole has a small head, with a short tail and very deep tail fins (Savage 2002). The dorsal fin extends onto the upper surface of the dorsum (Savage 2002). This tadpole is very light in coloration, except for some fine, veiny lines on the tail (Savage 2002). The eye is golden (Savage 2002). Tadpoles feed on vegetation in ponds (Savage 2002).

Ecology behavior and evolution

Call

A number of short, very nasal "ah-ah-ah-ahs" (Duellman 1970, Lee 1996).
