Near Threatened (IUCN 3.1)
Sections

Common name

Volcan Barba Treefrog

Caption

Isthmohyla picadoi is interesting because populations of these frogs continue to persist in areas where other amphibian populations have declined due to chytrid fungus.

Identification

Adult

Species description based on Duellman (2001) and Savage (2002). A small, rather squat treefrog: males to 32 mm, females to 35 mm.

Dorsal

Dorsal coloration ranges from yellow to orange to olive brown. Some darker markings may be present, including an indistinct brown line that runs from behind the eye along the side of the body towards the groin, a dark spot on the top of the head, and a dark bracelet at the wrist. The skin of the dorsum is covered in very small bumps.

Ventral

The venter is white and slightly bumpy in appearance.

Eye

The iris is coppery red.

Extremities

The fingers and toes are relatively short and thick, and end in large terminal discs.

Life history

Breeding season

Males call throughout the rainy season (Savage 2002). These frogs breed in bromeliads (Savage 2002).

Tadpole

The tadpole body is flattened, with a long, thin tail with low tail fins. Tadpoles are grey, with a lighter ventral surface and tail fins.

Ecology behavior and evolution

Ecology

These frogs are commonly found in bromeliads (Stuckert et al. 2009).

Call

The call has been described by Lindquist and Cossel (2007).

Behavior and communication

Although this behavior has not been directly observed, females probably feed tadpoles unfertilized eggs (Savage 2002).
