Forest Silver-stiletto

Pandivirilia melaleuca

Unknown

Overview

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

The Forest Silver-stiletto faces significant pressure from deforestation and habitat fragmentation across its limited range in southeastern Australian forests. Urban expansion and agricultural conversion have reduced suitable eucalyptus woodland habitat, while climate change is altering the moisture regimes essential for this species' survival. Invasive plant species further degrade remaining habitat quality by outcompeting native vegetation that supports the stiletto fly's prey base.
