Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Dictyna major faces severe population declines due to habitat destruction from urbanization and agricultural expansion, which eliminates the specific microhabitats this specialized spider requires. Climate change and pollution further threaten remaining populations by altering the delicate ecological conditions necessary for web construction and prey availability.
Key Facts
Habitat & Distribution
This species inhabits specific microhabitats including bark crevices of mature deciduous trees, wooden structures, and stone walls in temperate regions. It constructs distinctive mesh webs in sheltered locations with appropriate humidity and temperature conditions.
