ROVARTANI KÖZLEMÉNYEK LIX 1998 pp. 115-119 Life-habits of the Central European species of Periscelididae (Diptera)* L. Papp Life-habits of the Central European species of Periscelididae (Diptera). - Data on the development of larvae and bionomics of adults of the species Periscelis (Myodris) annulata (Fallén, 1813) and P. (Periscelis) nigra minor, P. (Periscelis) winnertzii Egger, 1862 are collections of periscelidids are also given. There are rather little known about the details of the development of periscelidid species of the world. The "obligate" notice, that they develop in sap of trees are repeated in all handbooks, but e. g. until 1988 only one (1) specimen of authentical periscelidid larvae was known (Teskey 1976, cf. Teskey 1987; for more copies of that figure see in the "References" in Papp 1995). Recently, the larvae of Periscelis (Myodris) kabuli L. Papp (Papp 1988) from Afghanistan and of P. (M.) annulata (Papp 1995) from Hungary were described. Parallel with the hunt for adults and larvae, rather numerous data on the bionomics of Periscelis species in Hungary were collected. A summary of those data is published in this paper. The fourth species of Periscelididae (Periscelis annulipes Loew, 1958; cf. Papp 1984) in Central Europe is rare and little known, its larvae are still unknown. The morphological description of the larvae of Periscelis winnertzii and P. nigra minor will be given in a forthcoming paper. Rearing trials with larvae of Periscelis (Myodris) annulata (Fallén, 1813) 16 May, 1996 After collecting the larvae in the Halmi-erdő (forest) (Pestszentlőrinc, Budapest), nine third instar larvae were put in a 80 mm long vial of 20 mm diameter and were kept at room temperature of 24+/-2 °C. The larvae were laid on elm-tree bark cut from under oozing sap of the tree and so bark was wet. The vial was closek with a tissue paper plug and was covered by aluminium foil in order to keep larvae in dark. The bark was regularly wetted with tap water. Later (on the 2nd of June) other two third instar larvae were added but they were smaller and died in the first half of July. *This study was supported by the Hungarian National Scientific Research Fund (OTKA, No. T16892).
