Cacopsylla rhamnicola

Unknown

Overview

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

Cacopsylla rhamnicola faces severe population declines primarily due to the loss and fragmentation of its specialized buckthorn (Rhamnus) host plant habitats across northern Europe. Agricultural intensification and urban development have eliminated many traditional hedgerow systems where buckthorn thrives, while climate change is shifting suitable habitat ranges northward faster than the species can adapt. The psyllid's highly specialized relationship with specific Rhamnus species makes it particularly vulnerable to any disruption in host plant availability.

Threat summary

Habitat

This specialized psyllid inhabits hedgerows, woodland edges, and scrubland where its host plants, various Rhamnus (buckthorn) species, are found. It requires mature buckthorn stands in semi-natural landscapes, particularly favoring areas with diverse shrub communities that provide shelter and alternative resources.
