First record of Ceriagrion fallax Ris (Odonata: Coenagrionidae) preying on small web-building spiders (Arachnida: Tetragnathidae)


In montane forest of south-western Yunnan, China, a female of Ceriagrion fallax was observed and photographed preying on a small web-building spider of the genus Leucauge. This is the first record of plucking an orb-weaver spider by a representative of the genus Ceriagrion. A brief discussion on the evolution of spider feeding behaviour in odonates is provided.
