Kovács Tibor: A Mátra szitakötői (Odonata)

Tibor Kovács The dragonflies of the Mátra Mountains (Odonata) The first summary of dragonfly data of the Mátra mountain region was done in 1987 by Sándor Tóth. The last 20 years, as well as results of larvae and exuvia research completed in the meanwhile have justified the drafting of this paper. Our investigational range has been within the area encompassing the stream of Zagyva, Tarna, the 23

r

d Highway and the Hatvan-Füzesabon railway. Imago details apart from the above publication have been found in four articles, of which one describes the appearance of a species (Hemianax ephippiger) not yet collected from the mountain. In our country and in the Mátra the intensive investigation of larvae and exuviae linked to the evolutionary site - the concrete waterbody - began at the beginning of the 1990s. Thanks to these efforts the number of fauna species has risen by five (Cordulegaster bidentata, Anax parthenope

, Erythromma najas, Orthetrum albistylum

, Somatochlora metallica

) and the number of dragonflies detected in larvae and/or exuviae form has also seen a significant increase. Today 53 species of Odonata are known from the Mátra: 38 in larvae/ exuviae, while 49 in imago form. 108
