Behavior

Activity Patterns

Black-eyed tree frogs are nocturnal, spending the day concealed in vegetation or under tree bark. At dusk, they emerge to hunt and call for mates.

Vocalizations

Male black-eyed tree frogs produce a distinctive mating call that sounds like a rhythmic "tree frog, tree frog." This call is used to attract females during breeding season.

Tree Climbing

These agile frogs are adept climbers, using their adhesive toe pads to ascend trees and vertical surfaces. They spend most of their time in the canopy, where they feed on insects and seek shelter.

Diet

Black-eyed tree frogs are insectivores and feed on a variety of small invertebrates, including:
- Crickets
- Grasshoppers
- Flies
- Moths
- Spiders
- Ants

They typically hunt at night, using their keen eyesight and quick reflexes to capture prey.

Reproduction

Mating Season

Breeding season for black-eyed tree frogs occurs in the spring and early summer, when males begin calling for mates. Females lay their eggs in small clusters on leaves or twigs overhanging water bodies.

Eggs and Tadpoles

The eggs develop into tadpoles within 5-12 days. Tadpoles metamorphose into juvenile frogs after 4-8 weeks.

Conservation Status

Black-eyed tree frogs are not considered threatened or endangered at the global level. However, population declines have been observed in some areas due to habitat loss and fragmentation, as well as pollution and disease.

Conservation Efforts

Efforts to protect and conserve black-eyed tree frogs include:
- Preserving and restoring forest habitats
- Reducing pollution
- Monitoring and managing invasive species
- Educating the public about their importance
