Tychius squamulatus

Local name: käringtandsbaljvivel

Unknown

Overview

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

Tychius squamulatus faces severe population declines primarily due to habitat loss from agricultural intensification and urban development across its European range. The species' dependence on specific leguminous host plants makes it particularly vulnerable to changes in grassland management practices, including increased mowing frequency and pesticide applications that eliminate both the weevil and its food sources.

Threat summary

Habitat

This weevil species inhabits grasslands, meadows, and field margins where its leguminous host plants grow, particularly favoring areas with Trifolium and Medicago species. It requires semi-natural grassland ecosystems with diverse plant communities and minimal disturbance from intensive management practices.
