Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Silver-edged Knot-horn faces significant pressure from habitat degradation in its specialized wetland environments, where agricultural expansion and water management practices have altered natural flooding cycles. Urban development along riparian corridors has fragmented remaining suitable habitat, while invasive plant species compete with native vegetation that supports the moth's larval development. Climate change-induced shifts in precipitation patterns threaten the delicate moisture balance required for this species' survival.
Habitat
The Silver-edged Knot-horn inhabits specialized wetland environments, particularly marshy areas with dense sedge and rush vegetation along slow-moving waterways. This species requires specific moisture conditions and native plant communities that support its larval feeding requirements.
