FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXIX. 1. 1976 p. 75-85 Some terricolous Sphaeroeerids and Drosophilids from Hungary (Diptera: Sphaeroceridae and Drosophilidae) By L. PAPP (Received 1 February, 1976) Abstract: Soil traps on important method for collecting species of these families; localities and locality data of 44 Sphaerocerid and 11 Drosophilid species with remarks (description of C. (Copromyza) pseudostercorària sp. n., four Sphaerocerid species new to Hungary, Limosina meijerei Duda bona species, first record of fully winged C. (Apterina) pedestris Meig. and of male of Drosophila hexasticha L. Papp, ect.). Finally a summary is given on the terricolous life-habit of flies and on features of terricolous species. It was noticed during the identification of the Sphaerocerid material of the Zoological Department of the Hungarian Natural History Museum (HNHM) for the series of Fauna Hungáriáé that besides the obligately coprophagous species also the terricolous Sphaerocerid species are strikingly poorly represented in the collection. This fact is easily understandable if we take into consideration that these species are not colleced or collected only in very low numbers by netting or singling. At the same time among the Sphaerocerids, which were collected by Dr. Z. KASZAB in Mongolia, many new species were described from soil trap materials. Thus, I decided to begin the methodical soil trapping of flies in Hungary. The placing and the*fitting into the soil of the soil traps for collecting flies need far more care and precise work than those of the traps for collecting large-bodied beetles or other insects. The rim of the plastic pits used must be placed 2-3 cm below the ground level and then the soil around the rim of the pit must be made declivous. When collecting in forest soils, it is advisable to have the rim of the pit deeply under the upper litter layers, i.e. to the lower level of the decomposed litter. Instead of pits, plastic cups are also useful, for killing and preseving Bquid it is advisable
