While the registration of dragonflies on man-made reservoirs of the Silesian Region took place, in 2006 there were recorded nu- merous males and less numerous females of Aeshna affinis. Single individuals have been reported in 1939 in Gwoździany and in 1966 in Ustroń. Since its last record Aeshna affinis has been noted again in 2005 in an old river bed of the River Odra River in Lasaki. It has been recorded on seven new sites in the next year. Most of those new sites were smali sinkhole ponds created by coal-mining. What is morę Aeshna affinis was recorded on a few natural sites too. While on natural sites there were 2-4 specimens recorded, on anthropogenic water bodies there were usu- ally about 20 individuals. Creating tandems indicated making attempts to inhabit anthropogenic water bodies by this species. There was another ąuite rare and stenothermic species - Crocothemis erythraea recorded on two sites together with Aeshna affinis. This species has been observed sińce 2002 in Odra River Valley, near the Southern bor- der of Silesian Region with Czech Republic. Nevertheless it was recorded for the first time in sinkhole ponds in 2006.

Two new localities (within 35 km) of the Scarlet Dragonfly were recorded on the clay pits in the South Wielkopolska region: 1) Odolanów (Ostrów Wielkopolski district, 51º35’ N, 17º39’ E, UTM: XT81): one ♂ on 28th May 2007; 2) Kotlin (Jarocin district, 51º54’ N, 17º40’ E, UTM: XT85): one ♂ on 23rd June 2007. Those records were made 4-48 km from localities detected by Żurawlew (2009) in Pleszew district (Fig. 1) and support his opinion about high importance of clay pits for this species. Both records came from Kartoteka Przyrodnicza Południowej Wielkopolski (Nature Database of the South Wielkopolska), the “citizen science” scheme, led by local group of the Polish Society for the Protection of Birds. The wider co-operation of the odonatologists with such groups and schemes is proposed in the article.
