Waarneming van solitaire ei-afzetting bij de Zuidelijke keizerlibel (Anax parthenope) in de Millingerwaard

Solitary oviposition of Anax parthenope was observed on 12th July 2006 in the Millingerwaard, near Millingen aan de Rijn in the province of Gelderland. This happened in a relatively small pond, circa 100 by 20m and with a maximum depth of 1,5m. This is the first documented observation of oviposition of Anax parthenope in the Netherlands. Oviposition and reproduction in The Netherlands are discussed, as well as identification, habitat preference and the occurrence of the species in Northwestern Europe.
