Its distribution has been studied essentially by the use of light traps. However its biology and habitat preferences are not sufficiently known and thus its habitats may be damaged by forest management. We suggest the beating method in order to collect larvae as an useful way to record and to survey D. schmidtii. Larvae of the species can be collected by beating branches of its host plants Quercus and Acer species in the lower canopy below 3 m . Optimal survey time would be the second half of May and the first half of June. Differences between the larvae of D. schmidtii and 16 similar moth larvae as well as Tenthredinidae Hymenoptera species living at the same time on the same trees are described and figured in a key to identification. The method described in the paper allows one to identify larvae in the field. Results are discussed. Keywords beating method Dioszeghyana schmidtii Habitats Directive 92 43 EEC larvae identification Lepido-ptera The Council of the European Communities has adopted the Directive 92 43 EEC http europa. eu scadplus leg en lvb 21 May 1992 Habitats Directive 92 43 EEC on the conservation of natural habitats and of wild fauna and flora. One of the goals of the directive is to maintain or restore at favourable conservation status fauna and flora of EU interest. Member countries of the European Union thus should study and regularly survey these species and their habitat requirements should be known. Dioszeghyana schmidtii Lepidoptera .
