English. A successful copula formation between a male of Libellula fulva and a female of L. depressa was documented photographically on 23. 6. 2022 at a small stream in the Natura 2000 site Ličenca pri Poljčanah in NE Slovenia. This represents the first record of an anomalous mating attempt with copula formation between the species involved. Their distribution in Slovenia as well as syntopic and syntemporal observations in the country are presented and briefly discussed, as are the site-specific factors and aged female coloration that may have contributed to the described rare attempt of heterospecific mating.

Dne 23. 6. 2022 je bila ob manjšem potočku v Natura 2000 območju Ličenca pri Poljčanah v SV Sloveniji foto dokumentirana uspešna tvorba paritvenega koleslja med samcem črnega ploščca Libellula fulva in samico modrega ploščca L. depressa. To je prvi zapis o poskusu parjenja s tvorbo paritvenega koleslja med vpletenima vrstama. Na kratko je predstavljena in obravnavana njuna razširjenost v Sloveniji ter prostorsko in časovno prekrivajoča se opazovanja v državi, prav tako pa so obravnavani specifični dejavniki na mestu opazovanja in obarvanost postarane samice, ki bi lahko prispevali k opisanemu redkemu poskusu heterospecifičnega parjenja.
