Overview of the Jersey Tiger Moth (Euplagia quadripunctaria)
The life cycle of the Jersey tiger moth (Euplagia quadripunctaria) is closely associated with riparian forests and tall hygrophilous vegetation along riverbanks. Across Europe, rivers and their surrounding habitats have been heavily modified through channel straightening, embankments, and other hydrotechnical interventions. These changes often involve the removal of vegetation or the creation of conditions unfavourable for its regeneration, leading to a reduction of suitable habitats and a decline in the species’ conservation status. In Bulgaria, many riparian areas have been affected—riverbeds have been straightened, canalized, and deepened. Protecting these environments is essential not only for this moth species but for the entire associated ecosystem.
The Jersey tiger moth is distributed across Southwestern Asia and Europe, with the majority of its population concentrated on the Balkan Peninsula. Beyond the Balkans, the species is rare, and its occurrence in other European regions is largely the result of migration. In Bulgaria, E. quadripunctaria inhabits shaded and moist forests and river valleys.
Major Threats to the Species
- Wildfires;
- Degradation of riparian forests and alterations in hydrological regimes;
- Use of biocides and hormonal substances in agriculture and forestry;
- Urban expansion and commercial development impacting the species’ habitats.
Project Goal
The project aims to develop an Action Plan for the conservation of the Jersey tiger moth.
The main activities include:
- Preparation and approval of the technical assignment for the Action Plan;
- Collection and analysis of existing information from published sources and historical datasets;
- Two years of field surveys in different seasons and habitat types, in accordance with the species’ ecology;
- Expert meetings and stakeholder consultations;
- Drafting of the first version of the Action Plan;
- Public consultations in Sofia and Stara Zagora;
- Incorporation of comments and recommendations and finalisation of the Action Plan.
Why Is It Important?
The conservation of Euplagia quadripunctaria is of high importance, as the species serves as an indicator of the ecological condition of riparian forests and wet habitats. Protecting the species contributes to the conservation of entire ecosystems and the many threatened species that depend on them. The development of the Action Plan outlines the measures needed for the restoration and long-term preservation of the species and its habitats.
