In spring of 2016the quadrifasciatus De Geer, 1776 species (Diptera, ) was recorded in the Republic of Moldova. The specimens of this spe- cies were observed in 03.IV.2016 on the plants from campus of SAUM. The species is aentomological curiosity, because imago presents phenomenon of the mimicrism and is very similar to wasps. For the first time in native literature, the species was mentions in “Animal world. . 1983”: “Species widespread in the USSR, Eastern Europe and Asia Minor is “bolishegolovka 4-h polosnaia” C.quadrifasciatus”. According to the passage it goes without saying that, the species is widespread in the Republic of Moldova too. Other sources indicated that the species spreads from Europe to Siberia, and most often in Central Europe. According to the database of the Fauna Europaea, this species is re- corded in the following countries: Andorra, Austria, Belgium, Britain, Czech Repub- lic, Denmark, Finland, Switzerland, France, Germany, Hungary, Ireland, Italy, Lithua- nia, Luxembourg, Poland, Slovakia and Sweden. For Moldova is indicated as – absent, but for neighbouring states as follows: Romania – present and Ukraine – absent. Description. The adult has 10-15 mm body length, and due to long legs has a great look . The dominant color is dark brown (Fig. 1). The head is large, dark brown and with long spindly antennae. The trunk is brown at the base and the rest black. The thorax is wider than longer, the prothorax being merged through a welding with mesothorax, while metathorax having sharpened aspect on base that obviously is fixed on propodeum. Prothorax has yellow “ocellus” on the shoulders; the feet are coloured in brown-light with more yellow. The abdomen is black with four yellow prominently transversal stripes, what reminiscent of that of wasps. The tip of the abdomen is frequently thickened and pointing up as at the scorpion.The egg presents a formationas an “anchor” with which it fixed during of flightto the host abdomen.The larvae hatch from the egg and penetrate the insect abdomen where consume it content andthere occurs pupal stage. Species develops one generation per year and overwinter in the imago stage. The C.quadrifasciatus species develops one generation per year and overwinter in the imago stage. Nutritional regime. Adults feeds withflower nectar of plants from families Compos- itae, (Umbelliferae) and (Labiatae). Larva is ectoparasite of insects from the Bombus (argillaceus, fragrans, muscorum, pomorum, ruderatus, zonatus) Andrena bulgariensis, Anoplius samariensis, Xylocopa violacea. Coincidentally, those species are included in the 3rd edition of Red Book of Moldova, published in 2015. IX-th International Conference of Zoologists, 12-13 October 2016 173
