Hakenmaskenzikade

Oncopsis appendiculata

Unknown

Overview

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

Oncopsis appendiculata faces significant pressure from habitat degradation in its specialized wetland environments, where drainage and agricultural conversion have reduced suitable breeding sites. Climate change poses an additional threat through altered precipitation patterns that affect the moisture-dependent plant communities this leafhopper requires. The species' narrow ecological requirements and limited dispersal ability make populations particularly vulnerable to local habitat disturbances.

Threat summary

Habitat

This leafhopper species inhabits moist grasslands, wetland margins, and boggy areas where it feeds on specific grasses and sedges. It requires consistently damp conditions and is typically found in areas with high water tables or seasonal flooding.
