Występowanie i stwierdzenie zachowań rozrodczych szafranki czerwonej Crocothemis erythraea (Brulle, 1832) (Odonata: Libellulidae) w powiecie pleszewskim (południowo-wschodnia Wielkopolska)

In the years 2007 and 2008 in the Pleszew Poviat over 60 study sites were controlled against the occurrence of dragonflies Odonata. 45 species were recorded within (61,6% of the dragonfly fauna in Poland). The Scarlet Dragonfly was recorded at four study sites (all of them were clay excavations): 1) Kwileń (51º59’N, 17º51’E, UTM: XT96), in 2007 – 4 observations 1♂, and in 2008 it was noted during 9 controls: the highest numbers 10 VI – ca. 15♂♂, 3 VII and 31 VII – each ca. 10♂♂, additionally,10 VI a pair in copula was observed, and next, 1♀ laying eggs in Batrachium sp.; 2) Kowalew (51º53’N, 17º43’E, UTM: XT85), 1♂ observed 11 VI 2008; 3) Nowa Wieś (51º52’N, 17º46’E, UTM: XT95), 1♂ recorded on 18 VI 2008; 4) Lenartowice (51º55’N, 17º48’E, UTM: XT95), 2♂♂ patrolling and territorial noted on 25 VI 2008. In Poland the stable populations of the Scarlet Dragonfly have been found so far in the valley of the Upper Vistula River and in Przemyśl Upland. Clay excavations are the environments that play very important role in the existence of many dragonfly species (Tab. 1). This refers not only to the Pleszew Poviat but also to the whole south-eastern Great Poland (Wielkopolska).
