PRETHODNO PRIOPĆENJE – PRELIMINARYCOMMUNICATION Šumarski list br. 7–8, CXXXV (2011), 353-360 UDK 630* 453 RAREAND THREATENED GEOMETRID MOTH Erannis ankeraria IN CROATIA: HISTORICAL REVIEW, DATAANALYSIS & PERSPECTIVES RIJETKAI UGROŽENAGRBICA HRVATSKE Erannis ankeraria – POVIJESNI PREGLED,ANALIZAI PERSPEKTIVE 12 Iva MIHOCI, Milivoj FRANJEVIĆ 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.

In category of protected taxa there are 14 but Geometridae(subfamilyEnnominae)– one of the two terflies, and in the category of strictly protected taxa most numerous lepidopteran families (Hausmann, 30 butterflies and 5 moths. Following systematic by 2001).The European fauna of Geometridae comprises Karsholt&Razowski(1996) these are:Eriogaster 957 species in total (Okyar & Mironov 2008), (Eriogaster) catax (Linnaeus 1758) (Lasiocampidae), while the number of species occurring in Croatia is Erannis ankeraria (Staudinger 1861) (Geometridae), nearly 440, representing about 45% of the overall Euro- Gortyna borelii lunata (Freyer 1839) (Noctuidae), pean geometrid faunaon approximately 0.55% of the Orthosia (Dioszeghyana) schmidti (Dioszeghy 1935) total European territory (Mihoci 2010).
