Wavy-lined Hopper

Stonasla undulata

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Stonasla undulata faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized habitat requirements make it particularly vulnerable to environmental changes, while its small population size increases extinction risk from stochastic events. Collection pressure for the pet trade has further reduced wild populations in accessible areas.

Threat summary

Habitat

Stonasla undulata inhabits specialized microhabitats within tropical forest ecosystems, typically found in areas with specific moisture and substrate conditions.
