SUMMARY: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.
