Ceriagrion tenellum (Small Red Damsel) is a mainly western-Mediterranean and western-European species, with only limited sites in northern Africa and the Balkans. In southern Europe, breeding mainly takes place on flowing water of streams but in the north-western reach of the range (e.g. The Netherlands, western Germany) Sphagnum peat bogs are preferred. In parts of Greece and the eastern Mediterranean Small Red Damsels are replaced by a very similar looking species, Turkish Red Damsel (Ceriagrion georgifreyi).
