bredsnabelmattevever
Centromerus semiater
The bredsnabelmattevever (Centromerus semiater) is a small sheet weaver spider characterized by its distinctive broad, flattened chelicerae and matte black coloration with subtle brownish markings. This diminutive arachnid plays a crucial role in controlling populations of small arthropods in its specialized microhabitat, constructing delicate horizontal sheet webs near ground level.

Species Profile
The bredsnabelmattevever (Centromerus semiater) is a small sheet weaver spider characterized by its distinctive broad, flattened chelicerae and matte black coloration with subtle brownish markings. This diminutive arachnid plays a crucial role in controlling populations of small arthropods in its specialized microhabitat, constructing delicate horizontal sheet webs near ground level.
Centromerus semiater faces significant threats from habitat degradation and fragmentation due to agricultural intensification and urban development across its European range. Climate change poses additional risks by altering the microhabitat conditions essential for this small spider species, while pesticide use in agricultural areas directly impacts both the species and its prey base.
Key Facts
