Overview

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

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.

Threat summary

Habitat

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.

Why is noords kaardertje classified as Critically Endangered?
noords kaardertje is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. 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.
Where does noords kaardertje live?
noords kaardertje occurs in Austria, Belgium, Canada, Cape Verde, Estonia, and Finland (plus 10 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to noords kaardertje?
The main threats to noords kaardertje are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
