Résumé :
In his 1990 paper Patrice Leraut postulated the division of the "Rock Grayling" known as Hipparchia alcyone into the two species alcyone and genava based on a different number of batons in the Jullien's organ. This bispecific concept turned out to be too simple in view of the wide diversity in the larval stages obtained by breeding some batches of alcyone originating from 7 European countries. Attention is focussed upon all the evolutionary stages of 3 stocks of H. alcyone vandalusica from the Granada province and one batch of H. a. pyrenaea from the Hautes-Pyrenees, compared to those of some alcyone cultures from the Pollino and Sila massifs. The material from southern Italy corresponds with Leraut's (1990) H. genava. In expectation of results of still current examinations, the Italian batches were provisionally attached to "alcyone" in accordance with the traditional monospecific concept. This research has been completed by the first results of a genetic analysis of the Italian, French and Spanish populations of the alcyone-complex. The method of "DNA microsatellite" has revealed a marked difference between the gene pool of the south Italian populations and those from France and Andalusia
