ROVARTANI KÖZLEMÉNYEK LVII 1996 pp. 291-293 Some notes on Heleomyzinae collected in Hungary (Diptera: Heleomyzidae) R. van der Weele Some notes on Heleomyzinae collected in Hungary (Diptera: Heleomyzidae) — Locality data of 11 Heleomyzinae species are given. Most of the species are rarely collected. The first female of Schroederella hungarica L. Papp et M. Carles-Tolrá, 1994, is recorded and briefly described. Some hints are given, where the development of the larvae of some species may take place. Heleomyzines are quite undistinguished looking flies. None of the flies is common. Furthermore, they have no economic significance whatsoever. This might explain why they are rather unknown and as a consequence unpopular among naturalists. Yet, they are very interesting. They are found mainly from late autumn to early spring when relatively few other flies are active, or in odd places such as caves and animal nests. Anyway, it is very unfortunate that so little is published about them. But below I will give information about those heleomyzines which I have been able to collect in recent times. Orbellia hiemalis (Loew, 1862) — It is not as rare as its congeners which are very rarely collected in Hungary. I collected this species in Budapest on several occasions during the months of November, December and January. Most specimens were caught on snow during sunny weather, but never in very high numbers. The flies I collected in Péterhalmi Forest (Péterhalmi-erdő) in Pestszentlőrinc were all caught on or in the direct neighbourhood of reeds. Also the female I collected in Nagytétény December 5th, 1994 on a factory wall was not far from the same habitat. This might give a clue where to look for its larvae which are unknown till now. Oldenbergiella seticerca L. Papp, 1980 — It is the only species of its genus which habitat is not restricted to the mountains. I do not think it is very rare in forests, though it is not often collected. As it counts for many members of the family Heleomyzidae, O. seticerca males seem to wait for females on the probable habitat where oviposition takes place; in this case droppings of large mammals. To collect them a certain care is required, because the animals are alert and escape easily, after which they are not very eager to return soon. I have in my collection specimens from Péterhalmi Forest, Budakeszi and Ocsa, but I observed them in Nagytétény as well. All specimens were collected in the period between November and March. Eccoptomera fdata Loew, 1862 — I have only one male Eccoptomera filata in my collection, captured on October 15th, 1995 in Péterhalmi Forest in Pestszentlőrinc. Because of their hidden way of life, the chance of finding species of Eccoptomera in open air is small. According to literature the larvae of E. filata develop in nests of rabbits and other small mammals (Papp 1981). Well, also my specimen was collected in a part of the
