Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Horseradish Flea Beetle faces significant pressure from agricultural intensification and habitat conversion, as its specialized feeding relationship with wild and cultivated Brassicaceae plants makes it vulnerable to changes in land use patterns. Pesticide applications targeting agricultural pests have likely contributed to population declines, while the loss of semi-natural grasslands and field margins has reduced available breeding and overwintering sites.
Habitat
This specialized beetle inhabits agricultural landscapes, field margins, and semi-natural grasslands where wild and cultivated Brassicaceae plants occur, including areas with horseradish, watercress, and related cruciferous species. It requires a mosaic of cultivated fields and natural vegetation for feeding, reproduction, and overwintering shelter.
