kustwolfspin
Xerolycosa miniata
Overview
The kustwolfspin (Xerolycosa miniata) is a small, reddish-brown wolf spider endemic to coastal dune systems along the North Sea. This ground-dwelling arachnid displays distinctive miniature proportions and russet coloration that provides excellent camouflage among dried vegetation and sand particles. As an active predator, it plays a crucial role in controlling populations of small arthropods within fragile dune ecosystems.
The kustwolfspin (Xerolycosa miniata) is primarily threatened by coastal habitat destruction and fragmentation due to urban development, tourism infrastructure, and sea level rise. The species' highly specialized habitat requirements and limited distribution make it particularly vulnerable to these anthropogenic pressures.
Habitat
This species inhabits the sparse, sandy areas between marram grass tussocks in primary and secondary coastal dunes, particularly favoring zones with partial vegetation cover that provide both hunting grounds and shelter. It constructs shallow burrows in stabilized sand deposits within 500 meters of the high tide line.
