Hypselistes jacksoni

Unknown

Overview

The fuktvorteedderkopp (Hypselistes jacksoni) is a distinctive orb weaver spider characterized by its iridescent carapace and intricate geometric web patterns featuring spiral reinforcements. This medium-sized arachnid plays a crucial role as both predator of flying insects and prey for insectivorous birds, helping maintain ecological balance in its specialized habitat.

Primary threats include habitat fragmentation from coastal development and the introduction of invasive plant species that alter the structural complexity of its web-building sites. Climate-induced changes in precipitation patterns are also disrupting the delicate moisture balance required for successful reproduction and prey capture.

Threat summary

Habitat

This species inhabits the transitional zones between coastal dune vegetation and maritime forests, specifically favoring areas with dense shrub understory that provides optimal anchor points for web construction. It requires environments with consistent humidity levels and protection from strong coastal winds, typically found 50-200 meters inland from active shorelines.

Frequently asked questions

Why is Hypselistes jacksoni classified as Endangered?
Hypselistes jacksoni is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Primary threats include habitat fragmentation from coastal development and the introduction of invasive plant species that alter the structural complexity of its web-building sites. Climate-induced changes in precipitation patterns are also disrupting the delicate moisture balance required for successful reproduction and prey capture.
Where does Hypselistes jacksoni live?
Hypselistes jacksoni occurs in Austria, Belgium, Canada, China, Denmark, and Estonia (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 Hypselistes jacksoni?
The main threats to Hypselistes jacksoni are habitat loss and human disturbance. The full IUCN-classified threat record for this species is detailed on the species page.
