Overview

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

The fläckig ärtvivel faces severe population declines primarily due to intensive agricultural practices that eliminate the diverse leguminous plants it depends on for survival. Modern farming methods, including widespread pesticide use and habitat simplification, have drastically reduced suitable breeding and feeding sites. Climate change compounds these pressures by altering the distribution and phenology of its host plants, disrupting the weevil's carefully synchronized life cycle.

Threat summary

Habitat

This weevil inhabits semi-natural grasslands, field margins, and areas with diverse leguminous vegetation, particularly favoring locations with wild vetches and clovers. It requires traditional agricultural landscapes that maintain botanical diversity and avoid intensive chemical treatments.
