Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Temnostoma angustistriatum faces severe population declines due to widespread habitat loss from deforestation and agricultural conversion of its specialized woodland environments. Climate change is altering the phenology of both the species and its host plants, disrupting critical breeding cycles. The species' narrow habitat requirements and limited dispersal ability make it particularly vulnerable to landscape fragmentation.
Key Facts
Habitat & Distribution
Deciduous and mixed woodlands with abundant dead wood and tree hollows, particularly favoring mature forest edges and clearings with flowering plants. The species requires specific microhabitats including rotting tree stumps and fallen logs where larvae develop.
Threats
