Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Dinoptera collaris faces severe population declines due to widespread deforestation and habitat fragmentation across its limited range. The species' specialized habitat requirements and small population size make it extremely vulnerable to ongoing agricultural expansion and climate-induced changes to forest ecosystems.
Key Facts
Habitat & Distribution
Occupies mature deciduous and mixed forests with dense canopy cover, particularly favoring oak and beech woodlands between 200-800m elevation. Requires dead and decaying hardwood trees for larval development, making it dependent on forests with natural succession processes.
