Rare and threatened geometrid moth Erannis ankeraria in Croatia: historical review, dana analysis and perspectives.

A “winter moth” Erannis ankerariais one of the most threatened geometrid moths in Europe, listed on both Annex II and Annex IV of the EU Habitats Directive and assigned as strictly protected taxa in Croatia. There is a great lack regarding distribution, population trend parameters and conservation status of this moth in Croatia. According to historical data, an Angoran Umber occurred in Pula (Istria) and Kaštel Stari (Dalmatia), and current field research in potentially suitable habitats resulted without records. Therefore, future research should focus on an active involvement of lepidopterists and foresters in long-term monitoring of the species, where beside light trapping, more successful attracting methods as pheromone traps should be used. Obtained results could lead to management guidelines proposal on sites where the Angoran Umber occurs. Management guidelines or future species action plan should focus of maintaining structure and function of Angoran Umber habitat - light Pubescent Oak and Sessile Oak forests and forest edges, in order to fulfill ecological requirements and subsistence of the species.
